A warning shows on the display if the PV Analyzer detects reverse polarity at the start
of the test. Push
When the test is complete, the test results show in the I-V Curve Table:
STC column shows values
Pass/Fail indicators show for each row
MEAS (measured) column shows values
7. Push
to view a Graph display the of measured curve and STC curve on top of the NOM
area curve.
8. Use
to toggle between the two table and graph views:
Advanced Table View with an additional column that shows the measured values
Advanced Graph View shows the measured values as the black line
9. Push
to save the results to memory.
A confirmation message with ID number shows on the display and then returns to the test
screen with blank STC and MEAS data.
A question-mark shows on the PV model tab as a reminder to update the PV model
data if necessary.
Additional Tests
Diode tests are available to meet IEC 62446-1 Clause 8.2 requirements.
Bypass Diode Test
Bypass Diodes prevent the current flowing from good, well-exposed-to-sunlight solar cells
overheating and burning out weaker or partially shaded solar cells by providing a current path
around the bad cell.
To set:
1. Turn the rotary switch on the PV Analyzer to
