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.
(As shown)
Press ‘NEXT’ to switch to the Quick Charge Recognition Interface.
