Appendix B.
Remote calibration procedure
Step 1. Prepare the Model 2500 for calibration
1. With the power off, connect the Model 2500 to the controller IEEE-488 interface or
RS-232 port using a shielded interface cable.
2. Turn on the Model 2500 and the test equipment, and allow them to warm up for at
least one hour before performing calibration.
3. If you are using the IEEE-488 interface, make sure the primary address of the
Model 2500 is the same as the address specified in the program you will be using to
send commands. (Use the MENU key and the COMMUNICATION menu to
access the IEEE-488 address.)
