Measuring Insulation Resistance - Ideal 61-797 Manual De Instrucciones

1. Before starting the test :
(a) The circuit under test must be completely de-energized.
Check the fuse before testing.
Connecting to an energized circuit while the test is active will
blow the fuse.
See Testing the fuse later in this manual.
If the detected voltage is above 2V, ">2V" will appear on the
display.
In this condition, the test is inhibited.
(b) Short the test leads before measurement, and press the blue
button to compensate the probe resistance for <2Ω.
2. Lock mode : Press the Lock button to enter the Lock Mode.
Then press the TEST button to start the test. The test voltage will
continue to be applied until the TEST/LOCK button is pressed again.
3. The meter displays the ">" symbol and the maximum resistance for
the range when measured resistance is higher than the maximum
display range.

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 higher than the maximum
display range.
