Function Introduction

Charge

Two channels can work independently and serve two intelligent batteries separately. Active, pre-charge,

constant current and constant voltage are the stages of charging mode. The initial charging mode depends

on the battery voltage, so active and pre-charge don't happen to every batteries.

Test

Testing time is 30 seconds and the purpose is to check both the charging and discharging performances.

After finishing test, LED flickers with green colour and LCD reports the test result.

Normal:

Test OK

Shown on LCD

Abnormal:

Test NG

Shown on LCD

Possible causes and solutions for the abnormal:

1) Cause: battery voltage is too low to discharge

Solution: try to charge the battery to raise voltage

2) Cause: remaining capacity is too full to charge any more

Solution: try to discharge the battery to reduce the remaining capacity

3) Bad contact of battery connecting wires

4) Damaged battery

5) Tester trouble
