Before an Insulation Test
The Tester includes features and functions that let you adapt the test
to your requirements. These features let you:
•
define a test voltage
•
make a ramp test selection
•
set a time limit (duration) for the test
•
measure polarization index (PI)
•
measure dielectric absorption ratio (DAR or DAR[CN])
•
measure capacitance
Use these alone or in combination. Set, clear, or account for (as
appropriate) each feature before you start an insulation test. The
features are discussed in this section.
Preset Test Voltage Selection
To make a preset test voltage selection:
1.
With the Tester turned on, push to select TEST VOLTAGE.
2.
Push or to scroll through the preset test voltage options
(250 V, 500 V, 1000 V, 2500 V, 5000 V, and 10 000 V).
The test voltage selection shows in the upper-right of the
display.
Note
The actual test voltage can be up to 10 % higher than the
selected test voltage.
Program a Test Voltage
To set a test voltage in between the preset test voltages:
1.
Push or to scroll through the preset test voltage options
(250 V, 500 V, 1000 V, 2500 V, 5000 V, and 10 000 V). Select the
voltage closest to the level required.
2.
The selected test voltage appears in the upper-right of the
display.
3.
Push .
TV=xxxxV flashes in the lower-left of the display.
4.
Push or to increment and decrement the voltage.
5.
When the correct voltage level shows, push to go to the
function menu.
Do not push
. Doing so will return the test voltage to a
preset voltage selection.
Note
The test voltage can be up to 10 % higher than the test
voltage you select.
