3. OPERATION

3.1 General

If the magnitude of a parameter to be measured is uncertain, but
known to be within the maximum safe limits of the electrical tester,
manually set the range to maximum. E.g. If measuring AC voltage
and the voltage magnitude is unknown, set the range to 600V, then
if required select the correct range for a satisfactory reading.
If the electrical tester displays OL or -OL then the measurement
limits of the range have been exceeded.
