Move the cursor to the frequency domain. The following soft keys appear in the soft key area on the screen.

↑(++)

This soft key is used for coarse adjustment of the frequency.

(+)

This soft key is used to fine-tune the frequency. Each time you press this key, the frequency increases to the next higher frequency point.

(-)

This soft key is used for fine-tuning the frequency downward. Each time you press this key, the frequency decreases to the next lower frequency point.

↓(–)

This soft key is used for coarse adjustment to decrease the frequency.

Method 2 for Setting the Frequency:

You can select or set the test frequency using soft keys or the numeric keys. When you enter the desired frequency value using the numeric keys, the soft keys display the currently available frequency units (Hz, kHz, and MHz). You can use these unit soft keys to select the unit and enter the data. When you use the [ENTER] key to enter a frequency, the frequency unit defaults to Hz.

Special Note: Frequency combinations vary depending on the instrument model, but the setup is generally similar.

5.1.3 مستويات الاختبار

The instrument’s test level is set based on the root mean square (RMS) value of the test sine wave signal. The frequency of the sine wave signal is the test frequency, which is generated by the instrument’s internal oscillator. You can set either the test voltage or the test current.

Special Note: The test current set on the instrument is the output current value when the test terminals are short-circuited. The test voltage set on the instrument is the output voltage value when the test terminals are open-circuited.

Steps for Setting the Test Level:

There are two ways to set the test signal source level on the instrument. One is to use the soft keys, and the other is to use the numeric input keys.

Use the arrow keys to move the cursor to the level field. The soft-key area on the screen will display the following soft keys.

(++)

Press this soft key to increase the signal source output level.

(+)

Press this soft key to increase the signal source output level.

(-)

Press this soft key to reduce the signal source’s output level.

(-)

Press this soft key to reduce the signal source’s output level.

You can select or set the test level using soft keys or the numeric keys. When you enter the desired level value using the numeric keys, the soft key area displays the currently available level units (mV, V, µA, mA, and A). You can use these unit soft keys to enter both the unit and the data. When you use the [ENTER] key to enter a level value, the unit defaults to V or A.

Special Note: When you need to switch the test level between current and voltage, you must use the numeric keys in combination with the unit soft keys.

5.1.4 Test Range

You can select the appropriate range based on the impedance value of the LCR component being tested.

The instrument has 9 AC test ranges: 10 Ω, 30 Ω, 100 Ω, 300 Ω, 1 kΩ, 3 kΩ, 10 kΩ, 30 kΩ, and 100 kΩ.

Steps for Setting the Test Range:

Use the arrow keys to move the cursor to the range field. The screen will display the following soft keys.

AUTO: This soft key is used to set the range to AUTO mode.

HOLD This soft key is used to switch the range from AUTO mode to HOLD mode. When the range is set to HOLD mode, the range is locked to the current test range. The current test range is displayed in the range field on the screen.

(+) This soft key is used to increase the range in range lock (HOLD) mode.

(-) This soft key is used to decrease the range in range lock (HOLD) mode.

5.1.5 سرعة الاختبار

The test speed of an instrument is primarily determined by the following factors:

Integration Time (A/D Conversion)

Average Number of Measurements (Average number of measurements per session)

Measurement Delay (Time from Startup to Start of Measurement)

Time when measurement results were displayed

You can choose from three test speeds: FAST, MED, and SLOW.

Special Note: Generally speaking, test results are more stable and accurate when measurements are taken at a slower speed.

Use the arrow keys to move the cursor to the Speed zone; the soft-key area on the screen will display the following soft keys.

FAST Set the test speed to Fast mode

MED Set the test speed to medium mode

SLOW Set the test speed to slow mode

5.1.6 Triggering Methods

Trigger Mode: This field is used to select the instrument’s trigger mode—that is, whether the instrument is set to INT, MAN, AUTO, or EXT trigger. Move the cursor to the Trigger Mode field, and the following soft keys will appear:

MAN Set the trigger mode to manual

INT Set the trigger mode to internal trigger

AUTO Set the trigger mode to automatic

EXT Set the trigger mode to “External Trigger”

When the trigger mode is set to MAN, each press of the [TRIGGER] button on the front panel causes the instrument to perform one test.

When the trigger mode is set to INT, the instrument performs continuous, repeated tests.

When the trigger mode is set to AUTO, the instrument will automatically perform one test when the product under test is connected to the test terminals.

When the trigger mode is set to EXT, the instrument performs a test each time the HANDLER interface receives a pulse trigger signal.

When the trigger mode is set to BUS mode, the instrument performs a test each time the instrument interface (such as IEEE 488) receives a “TRIGGER” command.

If the instrument receives a trigger signal while a test is in progress, that trigger signal will be ignored. Therefore, the trigger signal must be sent after the instrument has completed the test.

When you need to trigger the instrument from the optional HANDLER interface, set the trigger mode to EXT.

Special Note: The BUS trigger mode cannot be configured on the instrument’s front panel. To set the instrument to BUS trigger mode, you must send the “TRIGger: SOURce BUS” command to the instrument via an external interface (such as IEEE 488).

5.1.7 Average Frequency

The instrument’s “Average Count” function calculates the average of the results from two or more tests. The average count range can be set from 1 to 255, in increments of 1.

Move the cursor to the Average field. The following soft keys appear in the soft key area on the screen.

↑ (+) This soft key is used to increase the number of measurement averages.

↓ (-) This soft key is used to decrease the number of measurement averages

Users can also enter the average number of times directly using the number keys.

5.1.8 Open-Circuit Calibration

The instrument’s open-circuit calibration function eliminates errors caused by stray admittances (G, B) in parallel with the component under test. See Figure 5-2. Open-circuit calibration includes full-frequency open-circuit calibration using the insertion method and single-frequency open-circuit calibration performed at specified frequency points. For single-frequency open-circuit calibration, please refer to the schematic diagram in Figure 4-2.

Press the soft key to perform a full-frequency short-circuit calibration; the instrument will measure the short-circuit parasitic impedance (resistance and reactance) at all testable frequency points. The full-frequency short-circuit calibration takes approximately 15 seconds. During the full-frequency short-circuit calibration, the screen displays the following soft keys.

يستسلم

This soft key stops the current short-circuit calibration test. The original short-circuit calibration data remains unchanged.

Press this soft key to perform a short-circuit full-range reset, turn off the short-circuit calibration function, or turn on the short-circuit calibration function.

Figure 5-5: Schematic Diagram of the Short-Circuit Calibration Function

5.1.10 Delay Time

Instrument trigger delay refers to the time interval between when the instrument is triggered and when measurement begins. The delay function allows you to set the trigger delay time. The trigger delay can be set within a range of 0 s to 60 s, in 1-millisecond increments.

The procedure for setting the trigger delay is as follows:

Move the cursor to the time domain.

Use the number keys to enter the delay time. After pressing a number key, the following unit soft keys appear in the soft key area on the screen:

msec Press this soft key to set the default input unit to milliseconds

sec Press this soft key to set the default unit of measurement to seconds

Users can also press [ENTER] to finish entering numbers.

Special Note: The trigger delay function is particularly useful when the instrument is used in an automated test system. After the instrument is triggered via the HANDLER interface, the trigger delay ensures that the device under test makes reliable contact with the test terminals.

5.1.11 Output Resistance (Internal Resistance)

The instrument offers up to four selectable signal source impedance modes: 30 Ω and 100 Ω. To ensure data comparability with other tester models when testing inductors and MLCC capacitors, it is essential to use the same signal source impedance mode as those models.

30 Ω is comparable to: 107X/GR1689

100 Ω is comparable to: HP4284A/E4980/chroma3250

Move the cursor to the internal resistance field. The following soft keys appear in the soft key area on the screen.

30 Ω Set the output resistance to 30 Ω

100 Ω Set the output resistance to 100 Ω

Special Note: For detailed information, please refer to the instrument specifications; the internal resistance mode varies depending on the model.

5.1.12 Compensation Function

Because the parameters of the device under test vary with conditions such as temperature and frequency, it may sometimes be necessary to compensate for the test results. The compensation function can be applied to primary parameters, secondary parameters, or both primary and secondary parameters simultaneously.

The process for setting the compensation value is as follows:

Move the cursor to the Compensation A or Compensation B field: Use the numeric keypad to enter the value for Compensation A (primary parameter) or Compensation B (secondary parameter) directly.

If the value of compensation A or compensation B is not zero, the result displayed will be the measured value minus the compensation value.

Move the cursor to the compensation settings field and use the numeric keys to enter the values for Compensation A and Compensation B.

Figure 5-6: Schematic Interface of the Compensation Function

5.1.14 Auxiliary Tools (Tools)

5.1.13 إدارة الملفات (الملفات)

Please refer to Section 4.3, “File Management (Files).”

5.2 < Limit List Settings> Page

The instrument can sort items into up to five categories: three “pass” categories, one “fail” category, and one additional category.

Press the [Settings] menu key, then press the “Limit Settings” soft key to enter the < Limit List Settings> page, as shown in Figure 5-7.

Set the upper and lower limits for the channel comparison, select the comparison method (%), ABS, or direct reading, and turn on the channel comparison switch.

Figure 5-7: < Limit List Settings> Page

The instrument can be configured with three limit ranges for primary parameters and one limit range for a secondary parameter. Test results can be sorted into up to five bins (BIN1 through BIN3, BIN OUT, or an auxiliary bin). If a test piece’s primary parameters fall within the limit ranges for BIN1 through BIN3, but its secondary parameters do not, the test piece is sorted into the auxiliary bin. On the < Limit List Settings> page, you can configure the limit parameters for the following comparison functions:

Special Note: When the instrument is used with the HANDLER interface as part of an automated test and sorting system, its comparison function truly demonstrates its superiority.

5.2.1 Swapping Parameters

The parameter swap function allows users to swap the primary and secondary parameters in the parameter field, providing greater flexibility in using the instrument. For example: When the test parameters are Cp-Q, the parameter swap function changes the test parameters to Q-Cp. In this case, three pairs of comparison limit values can be set for Q, while only one pair of comparison limit values can be set for Cp.

Move the cursor to the parameter field, and the on-screen soft-key area will display the following soft keys:

Swap Parameters: Press this soft key to swap the primary and secondary parameters.

5.2.2 Sorting Methods

It includes three sorting methods: Direct Reading (DIR), ABS, and %.

Direct reading: The actual test results are set as the limit values.

ABS: The deviation value of (measured result – nominal value) is set as the limit value.

%: The deviation value, calculated as (measured result – nominal value) / nominal value, is set as the limit value.

Special Note: If upper and lower limits have already been set, you must first clear the limit list before changing the limit mode.

In tolerance mode, the setting of limit values is relatively flexible; the lower limit does not necessarily have to be less than the nominal value, and the upper limit does not necessarily have to be greater than the nominal value. The limit ranges for each range may be discontinuous or may overlap.

When the limit value is set to tolerance mode, the error ranges should be set in ascending order whenever possible. If the error range set for BIN 1 is the largest, all test pieces will be sorted into BIN 1, which is not conducive to detailed data categorization.

5.2.3 Auxiliary File ON/OFF (Auxiliary)

When you need to filter secondary parameters, you can set their limit values in the upper and lower bound settings for “2nd.”

There are three scenarios regarding the sorting of secondary parameters, as described below:

On the < Advanced List Settings> page, if no upper and lower limits are set for the secondary parameters, no sorting based on those parameters will be performed.

On the < Extreme List Settings> page, the upper and lower limits for the secondary parameters have already been set. However, the “Attachment” feature is set to OFF.

At this point, only devices that meet the secondary parameter requirements will have their primary parameters sorted according to the sorting limits. If the secondary parameters do not meet the requirements, all such devices will be sorted into the BIN OUT category, even if their primary parameters fall within the set limits.

On the < Extreme List Settings> page, the upper and lower limits for the secondary parameters have already been set. Additionally, the “Attachment” feature is set to ON.

If the primary parameter is outside the set tolerance range, the part will be sorted into the BIN OUT category. If the primary parameter of the part under test is within the tolerance range but its secondary parameter is not, the part will be sorted into the secondary category.

Special Note: When only the lower limit value is set for the secondary parameter and the auxiliary grade is set to ON, if the main parameter of the workpiece falls within the limit range but the secondary parameter value is less than or equal to the lower limit value of the secondary parameter, the workpiece is sorted into the auxiliary grade. Similarly, when only the upper limit value is set for the secondary parameter and the “Supplementary Class” setting is ON, if the main parameter of the test piece falls within the set limit range and the secondary parameter value is greater than or equal to the upper limit value of the secondary parameter, the test piece is sorted into the supplementary class.

5.2.4 Comparator Function ON/OFF (Comparison)

Move the cursor to the comparator function area, and the following soft keys will appear in the soft key display area on the screen:

ON Press this button to enable the comparison feature

OFF Press this button to turn off the comparison feature

The instrument can be configured with three limit ranges for primary parameters and one limit range for a secondary parameter. Test results can be sorted into up to four bins (BIN1 through BIN3 and BIN OUT). If a test piece’s primary parameters fall within the limits of BIN1 through BIN3 but its secondary parameters do not, the test piece is sorted into the auxiliary bin.

Special Note: When the instrument is used with the HANDLER interface as part of an automated test and sorting system, its comparison function truly demonstrates its superiority.

5.2.5 Upper and Lower Limits for Each Range

The instrument allows you to set the bin limits for three primary parameters and one secondary parameter. Test results can be sorted into up to four bins (BIN1 through BIN3 and BIN OUT). The upper and lower limits for these primary parameters can be set within the upper and lower limit setting ranges for BIN1 through BIN3. The upper and lower limits for the secondary parameter can be set within the upper and lower limit setting range for “2nd.”

The process for setting the upper and lower limits is as follows:

Move the cursor to the tool field and press the soft key to clear the currently set file limits. If no upper or lower limits have been set, you can skip this step.

Set the test parameters for the comparison function, the nominal values, and the limit modes for the main parameters.

Use the numeric keys in the lower limit setting area for Range 1 to enter the lower limit value for Range 1. After entering the data, you can use the subscript soft keys (p, n, µ, m, k, M, *1) to enter limit values instead of the [ENTER] key. When using the [ENTER] key to enter limit values, the unit defaults to the same unit as the last limit entry. When you press soft key *1, the default units for limit values are F, H, or Ω. After entering the limit values for Range 1 in the lower limit field, the lower limit for Range 1 is automatically set to – (absolute limit), and the upper limit for Range 1 is automatically set to + (absolute limit).

The cursor automatically moves to the lower limit setting field for Channel 2. Repeat Step 1 until you have entered the limit values for Channel 9. The cursor will then automatically move to the lower limit setting field for Channel 2.

After entering the lower limit for the secondary parameter, the cursor will automatically move to the upper limit input field for “2nd.”

Enter the upper limit for the secondary parameter.

7. Remote Control User Guide

The instrument includes a total of five external interfaces: RS232C, GPIB (optional), USBTMC, USBCDC, and USBHID. The instrument can be controlled remotely using any of these external interfaces.

7.1 RS Interface Description

The RS-232 serial communication standard, also known as the asynchronous serial communication standard, where “RS” stands for “Recommended Standard” and “232” is the standard number, is a standard published by the U. S. Electronic Industries Association (IEA). It specifies the transmission of one bit at a time over a single data line. RS-232 interfaces typically come in 9-pin (DB-9) or 25-pin (DB-25) configurations, with the DB-9 being the more commonly used type. Its pin definitions are shown in Table 7-1.

The connection between the host PC and the instrument is shown in Figure 7-1.

Figure 7-1: Diagram of the Connection Between the PC and the Instrument

The instrument’s RS-232 interface offers a variety of baud rates ranging from 9600 to 115200, with no parity, 8 data bits, and 1 stop bit.

The instrument’s commands (for details, refer to the section on commands) comply with the SCPI standard. After a command string is sent to the instrument, an LF (hexadecimal: 0AH, ASCII: 10) must be sent as the terminating character. The instrument can accept a maximum of 2048 bytes in a single SCPI command string.

7.2 GPIB Interface Description

The IEEE 488 (GPIB) General-Purpose Interconnect Bus is an internationally recognized bus interface for intelligent instruments. IEEE stands for the Institute of Electrical and Electronics Engineers, and 488 is the standard designation. GPIB is an interface standard used to connect computers to peripheral devices that comply with the international standards IEEE 488.1, IEC 625, IEEE 488.2, and JIS C 1901.

A single computer, equipped with a GPIB control card, can perform data acquisition, data transmission, and control functions for one or more instruments, forming an instrument system that makes our testing and measurement work fast, simple, accurate, and efficient. By connecting via GPIB cables, it is easy to configure star, daisy-chain, or hybrid configurations.

The instrument complies with the IEEE 488.2 standard, and the interface board can be inserted into any of the three expansion slots. The control command system is open; users can either use the computer interface provided with the product or write their own programs based on this control command system to achieve their objectives. The control command system supports all instrument functions, meaning that the full range of instrument operations can be performed on the control computer to enable remote control of the instrument.

System Scale That Can Be Achieved with GPIB:

A single GPIB system can connect up to 15 devices.

The connection configuration can be star, linear, or a combination of the two, but a ring configuration is not permitted.

The length of the cables connecting the devices must not exceed 4 m. In a single GPIB system, the total cable length must not exceed 2 m multiplied by the number of connected devices (including the controller), and the total cable length in the system must not exceed 20 m.

The number of connectors connected to a single device must not exceed four; exceeding this limit will subject the connection points to excessive external force, which may cause a malfunction.

7.2.1 GPIB Interface Functions

The GPIB interface provides access to the test instrument’s various functions; the instrument can transmit, receive, and process data and commands via the bus. The functions of this interface are shown in Table 7-3:

7.2.2 GPIB Bus Address

The address range for the instrument’s GPIB parallel communication interface bus mode is 1–31. For information on setting the address, refer to Section 6.1.5, “Bus Address Settings.”

7.2.3 GPIB Bus Functions

The bus functions of the instrument’s parallel communication interface are implemented by the following commands.

ABORT I/O (IFC) is used to suspend all bus activity, stop receiving messages from the tester, and reset the interface to an idle state.

CLEAR LOCKOUT/SET LOCAL is used to control the instrument, enabling it to enter remote operation mode.

DEVICE CLEAR (SDC or DCL) resets the selected instrument or resets all instruments.

LOCAL (GTL) returns control to the local system, allowing a remote control device—which is acting as a listener—to return to local control.

LOCAL LOCKOUT (LLO) blocks local commands. When this command is executed, the remotely controlled instrument will block local messages upon receiving it.

REMOTE is used to set the instrument to remote control mode.

The SPOLL serial polling command is used to configure the bus address status byte. An 8-bit byte is used to mask and read data to determine the instrument’s operating status.

طلب الخدمة

When the instrument’s controller is executing a task, the instrument can send an SRQ (Service Request) control signal. The SRQ signal can be considered an interrupt; it notifies the controller that the instrument is ready to transmit information or that an error has occurred. When the instrument sends the SRQ signal, it also sets the status byte to 6 bits. Bit 6 is the RQS (Request Service) bit, which sometimes functions as a status bit during roll call connections. When the instrument is in serial roll call mode, it clears the RQS bit and the SRQ line. Each bit of the status byte can trigger an SRQ service request. Users can mask the status byte to determine which bit caused the instrument to set the SRQ line. For details, see “Status Byte.”

TRIGGER (GET) triggers a bus command. This command can be sent to the selected instrument or to all instruments designated as listeners. The instrument must first be designated as a listener, and then the bus trigger mode must be set to trigger mode before sending the trigger message.

7.3 USBCDC Interface

7.3.1 USBCDC Interface Configuration and Installation

When the bus mode is set to USBCDC bus (see Section 6.1.4), the USB DEVICE is emulated as a serial port (Vcom), allowing users to communicate with the instrument via the USB interface using an RS-232-like communication format. This resolves the issue where some computers, lacking a serial port, cannot communicate with the instrument using the RS-232 communication protocol.

USBCDC Interface Installation Instructions: Use a dedicated USB cable to connect the USB DEVICE port on the rear panel of the instrument to the USB port on your computer.

7.3.2 Installing the USBCDC Driver

If you are using the USB DC interface and connecting to a computer with a dedicated USB cable, the driver installation wizard will appear the first time you connect to the computer. Select “Install from a list or specific location,” as shown in Figure 7-4.

Figure 7-4 Driver Installation Wizard

You need to install the Vcom.inf driver file provided by the manufacturer. Select “Include this location in the search” to locate the path where the Vcom.inf file is located, as shown in Figure 7-5.

Figure 75: Specifying the Driver File Path

Figure 76: USBCDC Driver Installation Complete

Once the driver is installed, users will see “LS2786 USB VCom Port” in the computer’s Device Manager. As shown in Figure 7-7:

Figure 77: Device Manager showing the LS2786 USB VCom Port

In this case, the LS2786 USB VCom Port functions as a serial port. When a PC does not have a serial port, users can use their existing serial-based communication software in this mode, just as they would with a virtual serial port connected via USB.

7.4 USBTMC Interface

USBTMC stands for USB Test & Measurement Class. USBTMC is a communication protocol built on top of USB. With USBTMC, you can control your USB-connected instruments just as you would control GPIB-connected instruments; from the user’s perspective, controlling USBTMC-based USB instruments is identical to controlling GPIB-based instruments.

The instrument’s USBTMC interface is compatible with USB 2.0, USBTMC 1.0, and the USBTMC-USB488 protocol; users can control and operate the instrument via the USBTMC interface.

7.4.1 USBTMC Interface Configuration and Installation

When the bus mode is set to USBTMC bus (see Section 6.1.4), the USB DEVICE is configured as a USBTMC interface.

USBTMC Installation Instructions: Use a dedicated USB cable to connect the USB DEVICE port on the rear panel of the instrument to the USB port on your computer.

7.4.2 Installing the USBTMC Driver

Important Note: Before installing the USBTMC driver, you must first install the VISA software provided by LISUN.

If you are using the USBTMC interface and connecting it to the computer with a dedicated USB cable, the driver installation wizard will pop up the first time you connect to the computer. Select “Install the software automatically,” click “Next,” and the driver will be installed automatically, as shown in Figures 7-8.

Figure 7-8 USBTMC Driver Installation Wizard

Figure 7-9 USBTMC Driver Installation Successful

Once the driver is installed, users will see “USB Test and Measurement Device” in the computer’s Device Manager, as shown in Figure 7-10:

Figure 710: The USBTMC interface displayed in Device Manager

8. دليل مستخدم واجهة المعالج

The instrument provides users with a Handler interface, which allows for the convenient construction of automated component sorting systems. When the instrument is used in an automated component sorting and testing system, this interface provides interaction signals with the system and output signals for sorting results. The instrument’s Handler interface offers two sorting modes: Upon startup, the default settings are P3 (3-bin sorting, with three primary parameters and one secondary parameter) and P1 (1-bin sorting, with one primary parameter and one secondary parameter). For specific configuration details, refer to Section 6.2.6, “Bin Sorting (Sorting Mode) Settings.”

The instrument’s operating sequence is shown in Figure 8-5 below:

Figure 8-5: Instrument Timing Diagram

T1: The duration of the START signal must be greater than 2.5 ms. The instrument begins measurement when the STARTU signal transitions from high to low; the signal must be removed before T2 returns to low, otherwise another measurement may be triggered unintentionally. If no external START signal is present, pressing the START button on the instrument’s front panel will also generate a start signal.

T2: وقت القياس والحساب للجهاز؛ في نهاية T2، يتم إرسال نتائج الفرز إلى واجهة المعالج.

T3: The waiting time from when WAIT is inactive to when START is active. Determined by the mechanical transmission mechanism.

T4: زمن تحويل الإشارة التناظرية إلى الرقمية للأجهزة.

As shown in Figure 8-5, the valid measurement interval for the output of each component’s measurement and sorting results is the period from the end of the current T2 to the end of the next T2.

Steps for Comparing and Configuring the HANDLER Interface Limit Lists

Press the [System] key on the instrument to enter the system settings screen. Then, press the “Test Configuration” key on the soft keyboard to enter the test settings screen. Move the cursor to the “Bin Sorting” setting field and select “3 BIN” (three-bin sorting) or “1 BIN” (one-bin sorting). For more information, refer to Section 6.2.6.

Press the instrument’s [Settings] main button to enter the < Measurement Settings> screen, then press the “Limit Settings” soft key to enter the < Limit List Settings> page.

On the < Limit List Settings> page, configure the nominal value, upper limit, and lower limit. For detailed configuration information, refer to Section 5.3, “< Limit List Settings> Page.”

On the < Advanced List Settings> page, move the cursor to the comparison settings field. The soft key display area will show the ON and OFF soft keys. Press the ON soft key to enable the comparison function.

Switch to the < File Number Display> or < File Count Display> screen to perform the measurement.

Finally, configure the HANDLER interface to enable the OUTPUT/INPUT signals.

Special Note: The < File Count Display> also allows you to configure some additional features.

8.3 Methods for Improving Measurement Speed and Efficiency

When using the HANDLER interface to build an automated sorting system, measurement speed and efficiency are critical. With this in mind, users can employ the following two methods to improve test speed and efficiency:

Set the range to the highest inductance value you are likely to measure. For example, if the highest value you might measure is 20 mH, first let the instrument automatically select the range for 20 mH, and then lock the range at that value.

Test it on the < Component Measurement Display> page
