CALibration:SECure:CODE
CALibration:SECure:CODE
Syntax
CALibration:SECure:CODE <new_code>
Description
This command allows you to enter a new security code to prevent accidental or unauthorized calibrations. The specified code is used to unsecure the mainframe and all installed modules. To change the security code, you must first unsecure the instrument using the old security code, and then enter a new code.
For a more detailed discussion of the calibration procedures, see the Keysight 34970A/34972A Service Guide. Please refer to that guide before attempting to calibrate the instrument as improper use of the CALibration commands can adversely affect the accuracy and reliability of the instrument.
Used With:
- Internal DMM
Parameters
Name Type Range of Values Default Value <new_code> ASCII String A string of up to 12 characters. You do not have to use all 12 characters but the first character must always be a letter (A-Z). The remaining 11 characters can be letters, numbers (0-9), or the underscore character ("_"). Blank spaces are not allowed. This is a required parameter.
Remarks
- The security code is set to "HP034970" or "AT034972", depending on the product number, when the instrument is shipped from the factory. Note that the third character of the security code is a zero (0) and not a capital O.
- If you forget your security code, you can override the security feature. See the Keysight 34970A/34972A Service Guide for more information.
- The security code is stored in non-volatile memory, and does not change when power has been off, after a Factory Reset (*RST command), or after an Instrument Preset (SYSTem:PRESet command).
Example
The following command sets a new calibration security code (the instrument must be unsecured).
CAL:SEC:CODE T3ST_DUT165
