Calibration and Passwords
Calibration is not required after the mainframe has been repaired. All calibration information is
module-specific and resides in each power module.
However, if the A5 board that contains the calibration switches has been replaced, any calibration
password that has been set will be lost. Passwords that are used to prevent access to the front panel
Admin menu will also be lost.
The calibration password will automatically be reset to the factory default, which is zero (0). Front
panel access to the Admin menu will be unrestricted unless a password is set.
Refer to Password Protection for information on setting the calibration password as well as the Admin
menu password.
