Figure 6. 9-GΩ Resistor Verification
The following test verifies the minimum insulation resistance accuracy, of the 50 V
range, using a separate 50-kΩ resistor.
1. Connect a 50-kΩ, +-0.1%, 0.25 W, 25 PPM resistor to the UUT
and terminals.

2. Turn the UUT rotary function switch to the 50 V insulation range.
3. Press the UUT T key.
4. Verify that the Meter display reading is within the Limits of 0.00 and 0.10.
The following test verifies that the Meter will sense a voltage >30 V when present on the
circuit under test.
1. Connect the UUT
voltage output terminals.
2. Turn the UUT rotary function switch to an insulation function.
3. Apply 35 V, 50 Hz to the UUT.
4. Verify that the UUT displays >30 V in the primary display, and the red LED
lightning bolt comes on.
