Change the Admin/Calibration Password
The password must be numeric, and can be up to 15 digits in length.
After it has been changed, you can only enter the calibration mode by
providing the correct password.
If the password is lost or forgotten, access can be restored by setting an
internal switch that resets the password to “0” (zero) (refer to “Accessing
the Calibration switch” in chapter 4). Once you have set the password to
“0” (zero) with the switch, you can enter a new password using
Administrative Tools menu or using the CAL:PASS command. The new
password will become active when you log out of the Admin Menu or
send CAL:STAT OFF. After you have returned the switches to the normal
position, you can access the Administrative Tools menu with the new
password.
Front Panel: SCPI Command:
Press [Menu], then select Utilities,
Administrative Tools, Administrator
Login.
Enter the original password (or zero
if the switches have been set) in the
Password field and press Select.
In the Administrative Tools menu,

new password in the PIN field and

NOTE
If the message “Locked out by internal switch setting” or “Calibration is
inhibited by switch setting” appears, the internal switch is set to prevent
the password from being changed (refer to “Accessing the Calibration
switch” in chapter 4).
