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 53).
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 47).
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.
