Syntax

CALibration:SECure:STATe <state>,<code>

CALibration:SECure:STATe?

Description

This command unsecures or secures the instrument for calibration. This feature requires you to provide a security code to prevent accidental or unauthorized calibrations of the instrument. Before you can calibrate the instrument, you must unsecure it by entering the correct security 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

<state> Boolean {OFF|0|ON|1} ON

<code> 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.

Name	Type	Range of Values	Default Value
<state>	Boolean	{OFF\|0\|ON\|1}	ON
<code>	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

When you first receive your instrument, it is secured, and the security code is set to "HP034970" or "AT034972", depending on the product number. Note that the third character of the security code is a zero (0) and not a capital O.
Once you enter a security code, that code must be used for both front-panel and remote operation. For example, if you secure the instrument from the front panel, you must use that same code to unsecure it from the remote interface.
Unsecuring the instrument using this command enables the internal DMM to be calibrated.
To calibrate the internal DMM, use the CALibration? command.
The calibration security setting 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).

Return Format

The query returns 0 (OFF) or 1 (ON), indicating the current calibration security setting.

Examples

The following command unsecures the instrument. Note that the "HP034970" string applies to the 34970A; the "AT034972" string applies to the 34972A.

CAL:SEC:STAT OFF,HP034970

The following query returns the current calibration security setting. In this case, it is OFF.
