Calibration Procedures 3
34980A Service Guide 47
Time Required for Calibration
The 34980A can be automatically calibrated under computer control.
With computer control you can perform the complete calibration procedure and
performance verification tests in less than 30 minutes once the instrument is warmed-up
(see “DMM Test Considerations" on page 55).
Automating Calibration Procedures
You can automate the complete verification and adjustment procedures outlined in this
manual. You can program the instrument configurations specified for each test over the
remote interface. You can then enter readback verification data into a test program and
compare the results to the appropriate test limit values.
You must adjust the instrument using the remote interface. Adjustment cannot be
performed from the local front-panel. The instrument must be unsecured prior to
initiating the calibration procedure (see “Calibration Security" on page 49).
For further information on programming the instrument, see Chapter 2 in the 34980A
User's Guide.
For information about errors that may occur during the calibration procedure, see
“Calibration Errors" on page 86.
