group 0 as shown in the pic middle right)
Ah/Wh Recording Group(s):
1. Totally 6 recording groups available, indicated by number from 0 to 5.
2. To shift among the recording groups, Press and Hold the button for 2
seconds and release once the group number changed.
3. To clear the Ah data of current recording group, Press and Hold the button
for 5 seconds and release once the Ah data being zeroed.
Mode 2 To test Voltage, Current, Power, Resistance and Temperature of Current Ah/Wh recording group
(currently group 0 as shown in the pic middle right)
Power of Load and Equivalent load resistance:
1. Totally 6 testing groups available, indicated by number from 0 to 5.
2. To shift among the testing groups, Press and Hold the button for 2 seconds
and release once the group number changed.
Mode 3 To test Micro Resistance value and voltage drop through charging cable

Testing Group
Current
Reference Voltage and Current Value
Resistance, and voltage drop
Current Recognition Type
Testing Method:
1. Connect the meter between the adapter/power bank and the constant current load, so as to get the Reference
Voltage and Current Value
2. Keep the constant current load on meter, unplug the meter and load combo from the adapter/power bank,
connect the target testing cable(micro USB type) between the adapter/power bank and the meter and load
