Page 16: Measuring Low Resistance
4. Making Measurements 4.3. Measuring Low Resistance: The circuit under test must be completely de-energized. Check the fuse before testing. See Testing the fuse section later in this manual. Connecting the tester to an energized circuit while the test is active will blow the fuse.
Page 17: Measuring Insulation Resistance
4. Making Measurements 4.4. Measuring Insulation Resistance: The circuit under test must be completely de-energized before testing. Turn the rotary switch to the desired test voltage. Connect the probes to the circuit to be measured. The Tester automatically detects if the circuit is energized. If the detected voltage is above 30V, " > 30V "...
Page 18: Measuring Pi / Dar
4. Making Measurements 4.5. Measuring PI / DAR: Polarization Index (PI) is the ratio of the 10-minute insulation resistance to the 1 -minute insulation resistance. Dielectric Absorption Ratio (DAR) is the ratio of the 1-minute insulation resistance to the 30 second insulation resistance. Turn the rotary switch to the desired test voltage.
