Insulation Tester
Insulation Test
XW
Warning
To prevent possible electric shock or personal injury:
• Before and after tests, do a voltage test to conrm that the Tester does
not detect the presence of hazardous voltage. See
Table 3
.
• If the Tester beeps continuously before the insulation test starts and
there is hazardous voltage, disconnect test leads and remove power
from the circuit under test.
3. Push
to select 250 V, 500 V, 1000 V, or 2500 V.
4. Push
for 1 second to start the insulation test.
The Tester makes three beeps as the test begins, and
X
ashes on the display
to indicate potentially hazardous voltages may be present on the test terminals.
The display shows the insulation resistance after the circuit stabilizes. The bar
graph shows this value continuously (in real time) as a trend. See
Table 5
.
