The calibration security code must begin with a letter, and can contain letters, digits, and underscores. Lower case letters are converted to upper case.

The calibration code is shared by both channels. It does not matter which channel is specified (if any), the same code is shared by both and gives access to calibrate either.

If calibration security has not been previously disabled by

CALibration[<chan>]:SECure:STATe OFF, the HP E1429 generates the error 311,"Calibration security on". To disable the calibration security requires knowledge of the previous security code.

Before shipping, the factory sets the calibration security code to E1429. You should change it before you use your HP E1429 to prevent unauthorized calibration. Record the new security code and store in a secure place. If you forget the new code, defeating the security involves instrument disassembly.

The HP E1429 stores the security code in its non-volatile calibration memory which remains intact even with power off.
