CALibration[<
chan
>]
The CALibration command subsystem is used in the calibration of the HP E1429.
The HP E1429 has commands to prevent and detect accidental or unauthorized
calibration of the instrument. The CALibration subsystem includes both these
security-related commands and the actual calibration commands.

:COUNt?
CALibration[<chan >]:COUNt? returns a number that shows how often the
HP E1429 has been calibrated. Since executing the CAL:GAIN, CAL:ZERO, or
CAL:STORe commands increments the number, the CALibration:COUNt?
command detects any accidental or unauthorized HP E1429 calibration.

Comments • Executable when initiated: Yes
• Coupled Command: No
• Your HP E1429 was calibrated before it left the factory. Before using, read the
calibration count to determine its initial value.
• Both channels share the same counter, so it does not matter whether channel 1 or
channel 2 is specified; the same answer is returned for either.
• The HP E1429 stores the calibration number in its non-volatile calibration
memory which remains intact even with power off.
