Press and hold the ‘NEXT’ button to switch Data Group. The USB tester can provide a total of 10
groups of data to save and view. These are numbered 0-9.
With Data Groups 1-9 selected the current
mAh and mWh are saved after power off.
They will continue accumulating the next time
the tester is powered on. When the data
group selected is 0 then the current value of
mAh and mWh will be temporarily saved at
power off. When the device is next powered
on these values will be recalled and will begin flashing. When the accumulated mAh exceeds 1
mAh, the previous data will be cleared and accumulation will restart.
With a Data Group selected, press and hold the ‘PREV’ button to clear the mAh and mWh.
