Calibration Commands

For an overview of the calibration features of the instrument, refer to “Calibration Overview” in chapter 4 starting on page 155. For a more detailed discussion of the instrument’s calibration procedures,

see chapter 4 in the Ud :>EC7N gzxz Tyz

.

CALibration?

Perform a calibration of the instrument using the specified calibration value (CALibration:VALue command). Before you can calibrate the instrument, you must unsecure it by entering the correct security code. Returns “0” (PASS) or “1” (FAIL).

CALibration:COUNt?

Query the instrument to determine the number of times it has been calibrated. Note that your instrument was calibrated before it left the factory. When you receive your instrument, read the count to determine

its initial value. The calibration count is stored in vmemory in the mainframe. The calibration count increments up to a maximum of 65,535 after which it rolls over to “0”. Since the value increments by one for each calibration point, a complete calibration may increase the value by many counts. The calibration count is also incremented by calibrations of the DAC channels on the multifunction module.

CALibration:SECure:CODE <txyz

>

Enter a new security code. To change the security code, you must first unsecure the instrument using the old security code, and then enter a new code. The security code is set to “HP034970” when the instrument is shipped from the factory. The security code is stored in v

memory in the mainframe. The security code may contain up to 12

alphanumeric characters. The first character be a letter, but the remaining characters can be letters, numbers, or an underscore ( _ ). You do not have to use all 12 characters but the first character must always be a letter.
