Technical Indicators:

4. Current Measurement
Measurement Range: 0~200mA~2A~20A (Basic range 200mA~20A)
Accuracy: ±(Reading ×1%+2 digits)
5. Power Supply and Test Power Source
Instrument Power Supply: AC 220V±10% 50Hz
Instrument Test Power Source: AC 30V±10%/20A 50Hz
Precautions:
1. Test Voltage: If the impedance of the test object is unknown, you can first test with 2V. If the test current is less than 1A, you can switch to 30V for measurement.
2. Current Detection: Clamp the CT around the part where current needs to be measured. For example, it can be clamped onto the lead wire connecting the capacitor, not necessarily the capacitor bushing. If measuring total current, you can also directly clamp onto the voltage lead wire.
3. Clamp CT Orientation: The front of the current clamp should face the red clip (i.e., 2V or 20V) direction. At this time, the instrument automatically distinguishes between capacitance, inductance, or resistance.
4. Magnetic Field Interference: It is recommended to keep the clamp CT at least 1 meter away from the instrument. If measuring an inductor with severe magnetic flux leakage, it is recommended to keep at least 1 meter away from the inductor.
