Insulation Function, External Sense

The following test verifies that the UUT will sense a voltage > 30 V when present on
the circuit under test.
1. Connect the UUT INSULATION output terminals to the calibrator voltage output
terminals.
2. Turn the rotary switch to the INSULATION function.
3. Apply 35 V, 50 Hz to the UUT.
4. Verify that the UUT displays > 30 V in the primary display.
