 Operating Instructions 

 

Please check if any product component is damaged before use. Do 

not use if damaged component is found. 

Install battery according to the user manual. 

 

1. Power On/Off the Primary High-Voltage Clamp Sensor 

When “

” is pressed, the

 

high-voltage clamp sensor is powered on (with the indicator light “

” lit 

up) and it starts automatic testing. The testing results (current, pulse and others of the high-voltage 
end) are sent to the tester via wireless transmission. The indicator light “

” flashes continuously 

15 minutes after the clamp sensor is powered on, to indicate auto power off. After the indicator light 

” flashes continuously for about 30 seconds, the clamp sensor powers off automatically to save 

battery power. If “

” is pressed when the POWER indicator light flashes continuously, the clamp 

sensor can continue working. Press “

” to power off the clamp sensor. 

2. Power On/Off the Tester 

When “

” is pressed, the tester powers on and then enters receiving mode (picture below). The 

primary current is the testing data of the high-voltage end, the secondary current is the testing data
