Measuring Insulation Resistance
=
1. Before starting the test :
The circuit under test must be completely de-energized.
If the voltage detected is above 30V, ">30V" will appear on
the display. In this condition, the test is inhibited.
2. Press the blue button to display insulation resistance or
Leakage current during the test or when the test stops.
3. Lock mode: Press the Lock button to enter the Lock Mode.
Then press TEST button to start the test. The test voltage
will continue to be applied until the TEST/LOCK button is
pressed again.
4. Release the TEST button before removing the test leads
(to enable the tester to discharge capacitive circuits).
If the screen displays volts, wait until it reaches zero.
5. The meter displays the "＞" symbol and the maximum
resistance for the range when measured resistance is
