2. احتياطات السلامة
2.1 السلامة الكهربائية
قبل توصيل سلك الطاقة، تأكد من أن جهد التيار الكهربائي هو ٢٢٠ فولت تيار متردد ±١٠٪، وأن التردد ٥٠ هرتز أو ٦٠ هرتز. يجب استخدام مقبس ثلاثي الأطراف مزود بتأريض وقائي، ويجب ألا تتجاوز مقاومة التأريض الوقائي ٤ أوم. لا تقم أبدًا بقطع أو فصل سلك التأريض الوقائي، لأن ذلك يُعرّضك لخطر الصعق الكهربائي.
2.2 السلامة البيئية
Do not use in environments with flammable or explosive materials, strong electromagnetic interference, high temperatures and humidity, or excessive dust levels. Operating environment: Temperature 5°C to 35°C, relative humidity ≤ 65% RH.
2.3 إجراءات التشغيل
Before connecting the wires, the power supply to the sample load must be disconnected; do not connect wires while the circuit is energized. Connect voltage leads in parallel and current leads in series; under no circumstances should a current circuit be connected to a voltage terminal or a voltage circuit to a current terminal. Pay attention to the positive and negative polarities when performing DC measurements. After connecting the wires, tighten the terminals and ensure that no bare wires are exposed to prevent short circuits or electric shock.
When measuring high-frequency signals, keep the wiring as short as possible and use thick, multi-strand wire; route the wiring away from the metal casing of the equipment to minimize interference from distributed capacitance.

3.1 مقدمة عن اللوحة الأمامية
See Figure 3-1. Note: Using the desktop software makes operation more convenient and eliminates the need to use the front panel of the device; if you need to print a test report, you must also do so through the software. If you use the software, you only need to operate the power switch and load switch on the front panel.
