Additional Tests; Bypass Diode Test - Fluke SMFT-1000 User Manual

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
The display shows the Bypass Diode test mode. Push
does not show.
2. Use  to set the pass/fail limit for the bypass diode voltage measurement.
