. Measurement of DC voltage: Before measurement, adjust the gear knob of the clamp meter to the DC voltage gear, and connect the test lead of the clamp meter to the voltage of the device to be measured. Note that the red test lead is connected to the positive voltage of the voltage, and the black The test lead is connected to the negative pole of the voltage.
2. AC voltage measurement: Before measuring, adjust the gear knob of the clamp meter to the AC voltage gear, and connect the test lead of the clamp meter to the device that needs to measure the AC voltage. There is no need to distinguish positive and negative for AC voltage measurement. pole.
