Chapter 4 Features and Functions

Calibration Overview

To Secure Against Calibration You can secure the instrument either from the front panel or over the remote interface. The instrument is secured when shipped from the factory and the security code is set to “HP034970”.

•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.

•Front-Panel Operation:

SECURE CAL

When you enter the Utility menu, the calibration entries toggle between CAL UNSECURED and SECURE CAL. To secure the

instrument, select SECURE CAL and press

. After entering the

desired security code, press

again. When you return to the menu,

you will see new choices CAL SECURED and UNSECURE CAL.

•Remote Interface Operation: To secure the instrument, send the following command with the desired security code.

CAL:SECURE:STATE ON,HP034970

To Change the Security Code To change the security code, you must first unsecure the instrument, and then enter a new code. Make sure you have read the security code rules described on page 155 before attempting to change the security code.

•Front-Panel Operation: To change the security code, first make sure

that the instrument is unsecured. Go to the SECURE CAL entry, enter

the new security code, and press (the instrument is now secured with the new code). Changing the code from the front panel also changes the code as seen from the remote interface.

•Remote Interface Operation: To change the security code, first unsecure the instrument using the old security code. Then, enter the new code as shown below.
