2. 안전상의 주의
2.1 전기 안전
Before connecting the power cord, verify that the supply voltage is AC 220V ±10% and the frequency is 50 Hz or 60 Hz. You must use a three-prong outlet with a protective ground, and the protective ground resistance must be ≤4 Ω. Never cut or disconnect the protective ground wire, as doing so poses a risk of electric shock.
2.2 환경 안전
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 운영 절차
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. 장비 작동
3.1 전면 패널 소개
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.
