Calibration Security
This section describes the instrument's calibration security system. If you forget the security code, you can override
calibration security.

front panel, use that same code to unsecure it from the remote interface.

l Security code rules:
Unquoted string up to 12 characters
Must start with letter (A-Z)
May contain letters, numbers (0-9) and underscores
