Insulation Tester
Measurements
13
XW Warning
Before and after a test, confirm that the Product does
not indicate the presence of a hazardous voltage. See
Table 5. If the Product beeps continuously and a
hazardous voltage is shown on the display, disconnect
test leads and remove power from the circuit under
test.
3.
Push for 1 second to start the insulation test.
The Tester beeps three times as the test begins, and X
flashes on the display to indicate potentially hazardous
voltages may be present on the test terminals.
The display indicates the measured insulation resistance after
the circuit has stabilized. The bar graph displays this value
continuously (in real time) as a trend, see Table 7.
Any of these conditions terminate an insulation test:
•
User stop (push )
•
Timer limit reached
•
Interference on the test circuit
•
Breakdown occurs with ramp test enabled
•
Battery depleted
If breakdown occurs with ramp test enabled, push
before
going to step 4.
After the termination of an insulation test, the Tester beeps
when a potentially hazardous voltage remains on the test
terminals due to charged-circuit capacitance or from the
presence of an external voltage.
4.
When the test is terminated, STORE RESULT? shows on the
display. If appropriate, store the test results. See Store Test
Results. Or, push to terminate the STORE RESULT?
prompt. The results are not stored.
Store Test Results
When the insulation test is complete, the Tester shows
STORE RESULT? as a prompt to save the measurement results for
future use. The Tester includes enough memory to store the results of
99 insulation tests.
To store the results of an insulation test:
1.
Push to save the measurement results. The Tester will
assign and display a sequential tag number (00 to 99) to identify
the measurement.
2.
If the tag number is acceptable, push again to store the
data. If a different tagging convention is required, proceed as
follows to provide a custom 4-character tag.
Notice that * is blinking on the display. This is the first of the four
characters available for tagging the test results.
3.
Repeatedly push to cycle through the character positions.
