Power Supply 

 

The  meter can continuously  work for above 6 hours 

with a built-in  3.6V/2.1AH  Ni-MH battery. When the 

battery  voltage drops below 3.2 V, to remind the 

customer that the battery should be charged, the battery 

indicator  “

”  displays  on the top of the screen. 

Please power off the meter and charge it with the 

attached charger for 10~12 hours. 

 

 

 

1.The meter will automatically shut off 

and can’t be power on when the 

voltage of the built-in battery is lower 

than 3.1V to protect the battery from 

damage. 

     2.Be sure to charge the meter with the 

attached charger, otherwise it may 

cause damage. The company wouldn’t 

compensate any loss caused by 

incorrect charging.
