NI PXI-4130 Calibration Procedure
Verification
This section provides instructions for verifying the NI 4130 specifications.
Verification consists of generating and measuring a series of outputs using the NI 4130,
verifying the accuracy with the DMM, and comparing the results to the calibration test limits.
If the results fall within the test limits, the NI 4130 meets its published specifications, and
adjustment is optional. If the results fall outside of the test limits, you must adjust the NI 4130.
Verification tests the following NI 4130 specifications:
•
Voltage programming accuracy
•
Voltage measurement accuracy
•
Current programming accuracy
•
Current measurement accuracy
•
Voltage load regulation
•
