As the current passes, the caliper clamp 407 monitors the current fluctuation state through the current sensor in the clamping detection ring 406, and feeds back on the display screen 408. The voltage sensor monitors and feeds back on the flashing light 602. As the main screen 707 displays numbers, the first sub-meter 710 and the second sub-meter 712 rotate clockwise and counterclockwise through the pointer, one counts clockwise and the other counts counterclockwise, to monitor the stability of the meter current. When a disturbance error occurs, the feedback is fed back to the signal device through the antenna 702 for timely transmission.

As the main screen 707 displays numbers, the first sub-meter 710 and the second sub-meter 712 rotate clockwise and counterclockwise through the pointer, one counts clockwise and the other counts counterclockwise, to monitor the stability of the meter current. When a disturbance error occurs, it is fed back to the signal device for timely transmission through the antenna 702, thereby improving the overall anti-theft performance.
