 Operating Instructions 

 

Please carefully check before use if any component of the detector/receiver 

is damaged, do not use if any damage is found. 

Install battery according to the instructions in the user manual. 

1. Operate the detector 
1) Power on/off 

With the pressing of the button “

”, the detector powers on with indicator light lit up, then 

enters general testing mode. The detector powers off automatically about 15 minutes after it 
is powered on. 

2) General testing 

 

High voltage! Extremely dangerous! The operation must be performed by 

authorized trained personnel. The operator must follow the safety 

information strictly, otherwise it may present a risk of electric shock, which 

can cause personal injury or death. 

Danger! It is forbidden to test bare conductor or bus bar with voltage over 

110kV, otherwise it may present a risk of electric shock, which can cause 

personal injury or equipment damage. 

 

 

For high voltage testing, please connect the hot stick and fully extend it, and 

hold the protective end of hot stick by hand. 

Use the supplied dedicated hot stick only. 

Power on the detector, then use the hot stick to push the detector to approach the measured 
conductor, as shown in Figure A. Center the conductor at the bottom of the clamp jaws, as 
close as possible to ensure measurement accuracy, as shown in Figure B. Pull back the 
detector to remove form the conductor, as shown in Figure C.
