Remote calibration
Follow the steps in this section to perform comprehensive procedures via remote. See
Appendix G
When sending calibration commands, be sure that the Model 2790 completes each step
before sending the next command. You can do so either by observing the front panel
CALIBRATING message or by detecting the completion of each step over the bus.

As with front panel calibration, you can choose to perform comprehensive,
DC-only, or AC-only calibration. Be sure to include a space character between
each command and parameter.
Connect the Model 2790 to the IEEE-488 bus of the computer using a shielded
IEEE-488 cable, such as the Keithley Model 7007, or connect the unit to a com-
puter through the RS-232 port using a straight-through 9-pin to 9-pin cable (use a
9-25-pin adapter if necessary).
Turn on the Model 2790 and allow it to warm up for at least two hours before per-
forming calibration.
Make sure the primary address of the Model 2790 is the same as the address speci-
fied in the program that you will be using to send commands. (Use the GPIB key.)
