discharge is completed according to the discharge indication.
2
Do not remove the wiring during the measurement.

If the charging progress strip and the current display value stand still for a long time, it
indicates that the value of the resistance value to be measured is probably beyond the
measuring scope of the current, so it is not able to reach its set value. At this time, press the
“Exit” button to return and reselect the current to retry.
