Multifunction Electrical Tester Calibrator
Calibrate Insulation Resistance Testers
169
To do an Insulation Resistance calibration:
1. Push .
2. Using Figures 33, 34, or 35, connect the DUT to the Product’s HI Ω OUTPUT
HI and LO terminals.
3. Push the Mode softkey. Then, using the cursor keys or rotary knob, highlight
Resistance and select it by pushing the Select softkey or pushing in the
rotary knob.
4. Adjust the resistance value for the desired resistance.
W Caution
To avoid an overload condition, ensure the DUT test voltage is
below the Product’s allowed voltage limit before adjusting the
resistance value.
1. Set the test voltage on the DUT.
2. Push .
3. Activate the measurement on the DUT by pushing its start or test button.
The test voltage generated by the DUT is measured by the Product and
displayed in the PARAMETERS area of the display.
4. Compare the DUT reading with the resistance value in the OUTPUT area
of the display.
5. Stop the test by releasing the appropriate test button on the DUT.
6. Push to disconnect the output terminals from the DUT.
