4. After leads are configured, push
to start the R
INS
(2) measurement.
Note
The high voltage icon and dashes show during the measurement.
When complete the test results show on the display:
R
INS
(2): measured insulation resistance
V
INS
: applied test voltage during the insulation test
Passed:
and a short beep noise indicates the test passed when the results are greater
than the preset limits.
Failed:
and multiple beeps indicates the test failed when the results are less than the
preset limits.
5. Push
to save the results to memory.
A confirmation message with ID number shows on the display and then returns to the test
screen.
Note
If the resistance is outside an acceptable threshold from the R
INS
test (1 or 2), use the
Continuous test to find the exact location on the insulation where the resistance is
failing. See Continuous Measurement.
Continuous Measurement
You can measure R
INS
between any two measurement points in the PV system. This
measurement helps to troubleshoot insulation faults on the wiring cables. Fluke recommends
that you remove the solar modules for this test as they can influence the result.
To m e a s u re :
1. Turn the rotary switch on the PV Analyzer to R
INS
.
2. Push
to enter the R
INS
Continuous mode.
3. Use
to select the nominal test voltage (V
N
selection=50/100/250/500/1000 V).
This value will trigger the limit values.
Tip: Push
to see a connection diagram.
4. After you connect the leads, push
>1 s. to start the R
INS
Continuous measurement.
