When the voltage of the battery pack or the voltage of a single battery is less than the set voltage lower limit, or the set discharge duration or set discharge capacity has been reached during discharge, the tester will automatically stop discharging and record the discharge Real-time data of all valuable and continuous processes in the process.

Common faults and methods:

No.

Fault

Solution

1

The discharge current is abnormal.

Switch on the air circuit breaker. Make sure the discharge PCB is connected, the battery capacity is not small and the discharge current is not small.

2

Overtemperature

Inspect and make sure the tester is correctly placed and inspect the ventilation and the heat flow direction.

3

There is a current after the air switch is switched on following power-on.

Send the discharge PCB to its manufacturer to be repaired because it is possible that it is burned.

4

Failure of data saving

Restart the tester. Do not switch between internal storage and external storage during discharge.
