4.3.3 Password Protection

can be done only after the password is entered: span and zero settings,
alarm setpoints, analysis range definitions, switching between autoranging
and manual override, setting up an auto-cal, and assigning a new password.
However, the instrument can still be used for analysis or for initiating a self-
