Verification and Calibration 109
Front Panel Calibration
Eight shifted keys and the Entry keypad are used for calibration functions (see chapter 5 - Front Panel Operation for
explanations of shifted keys and the Entry keypad). The following procedures assume you understand how to operate front
panel keys.

Entering the Calibration Values
Follow the steps in Table B-5 for entering calibration values.
Saving the Calibration Constants
Storing calibration constants overwrites the existing ones in nonvolatile memory. If you are not
absolutely sure you want to permanently store the new constants, omit this step. The Agilent SAS
calibration will then remain unchanged.

calibration will then remain unchanged.
To replace any existing calibration constants with ones you have just entered, press
.
CAL SAVED then appears on the display.
Disabling the Calibration Mode
To disable the calibration mode, press
. The display will return to meter mode with the Cal annunciator off.
Changing the Calibration Password
The factory default password is the model number of your supply, such as 4350. You can change the calibration password
only when the Agilent SAS is in the calibration mode (which requires you to enter the existing password). Proceed as
follows:

2. Enter the new password from the keypad. (You can use up to 6 integers and an optional decimal point.) If you want
to operate without requiring any password, change the password to 0 (zero).
3. AGAIN will appear on the display. Enter the password a second time.
4. When OK is displayed, the new password has been accepted.
