shows how make the measurement setup better. Connect the Guard
terminal to the unused wire and attach it to the inner insulation. This ensures that
the Tester measures the leakage between the selected conductor and the outer
shield, but removes the leakage path between conductors.

Preset Test Voltage Selection
To make a preset test voltage selection:
1. Turn on the Tester.
2. Push
to scroll through the preset test voltage options (250 V, 500 V, 1000 V,
2500 V).
The test voltage selection shows on the display.
Note
The actual test voltage can be up to 10 % higher than the selected
test voltage.
Program a Test Voltage (1537/1537-II only)
To set a test voltage in between the preset test voltages, proceed as follows:
1. Turn on the Tester.
2. Push
to select the test voltage.
3. Continue to push
to scroll through the preset test voltage options (250 V,
500 V, 1000 V, 2500 V). Select the voltage closest to the level required.
The test voltage selection shows on the display.
4. Push
or to increase and decrease the voltage in 100 V steps until the
correct voltage level shows.
