Models 2510 and 2510-AT Calibration 2-21
Remote calibration procedure
Step 1: Prepare the Model 2510 for calibration
1. With the power off, connect the Model 2510 to the controller IEEE-488 interface or
RS-232 port using a shielded interface cable.
2. Turn on the Model 2510 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 2510 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.)
4. Send the following command to unlock calibration:
:CAL:PROT:CODE ‘KI002510’
5. Table 2-6 summarizes the various calibration steps and associated commands, which
are covered in more detail throughout the procedure.
