Section 4: Using the Model 9100: Insulation/Continuity Function (Option 135) 4.18-11
2. Select the desired resistance value on the 9100 screen, using either the Direct or Digit
Edit method.
3. Turn the 9100 output ON. The unit will beep for a few seconds before switching on
to indicate that high voltages may be present across the terminals.
4. Taking care not to touch any connections, push the test button on the UUT and note
the reading. Many insulation testers take several seconds to settle, especially on high
resistance values (above 10MΩ). Release the test button immediately after you have
performed the test.
You may adjust the Percentage Deviation and Offset fields or the absolute value of
resistance output while the UUT is on. However, always be aware of the settling time of
the UUT.
