Verification Procedure
Constant Voltage Tests
NOTE
Test each output channel individually. Refer to the appropriate test
record form for the instrument settings of the model you are checking.
Voltage Programming and Readback Accuracy
Test category = performance, calibration
This test verifies that the voltage programming and measurement
functions are within specifications.
1 Turn off the solar array simulator and connect a
DMM directly across
the sense terminals (see Test Setup figure A). Do not connect a load.
2 Turn on the solar array simulator and program the instrument as
indicated in the test record form under “Voltage Programming &
Readback, Min Voltage” with the load off. The CV annunciator
should be on and the output current should be close to zero.
3 Record the output voltage reading from the DMM and the voltage
measured over the interface. The readings should be within the
limits specified in the test record form under “Voltage measured
over interface” for Min Voltage.
4 Program the instrument as described in the test record form under
“Voltage Programming & Readback, High Voltage”.
5 Record the output voltage reading from the DMM and the voltage
measured over the interface. The readings should be within the
limits specified in the test record form under “Voltage measured
over interface” for High Voltage.
