AC current measurement:
Grasp the trigger, open the pliers, and clamp a wire of the tested circuit in the pliers for measurement. Non contact is safer
The instrument clamp can be opened up to 30mm, with a wider range of measuring currents, suitable for various wires
When AC voltage is detected, the LED red light will flash and an alarm beep will sound, indicating that the closer to
 the power supply, the more urgent the alarm will be
Automatic shutdown function: If there is no operation within 10 minutes, it will automatically shut down
