4.2.2 Compensation of test leads resistance

In order to eliminate the impact of the resistance of test leads on measurement result R

In order to remove the compensation of the leads resistance (return to default cal-
ibration), perform the above-mentioned activities with test leads open, instead of
test results, the display will show message oFF (compensation of test leads is
