Password Protection,
continued
Viewing Menu Items
All users can view all menu items, regardless of password level, without entering a
password.
Changing Menu Items
All users can execute all password level 0 menu items without entering a password.
Password level 1, 2 and 3 menu items can only be changed if the user belongs to the
group authorized for that level and after the user’s password has been entered.
Note
Entering the main menu and thus switching to the menu mode can be password
protected (see the “Inhibit Operation” section, page 79).
Change Privilege
After entering the password the user is authorized to change any menu items
accessible at the user’s level.
Duration of the Change
Privilege
The change privilege remains in effect until:
•
The analyzer automatically switches to measurement mode if the user has not
pressed a key for more than about 5 minutes (time out).
•
Or the user presses the “Meas” key twice in succession.
The change privilege remains in effect if the user presses the “Meas” key only once to
return to measurement mode. This is indicated by the “Password active” status
message.
In this manner the user does not have to re-enter a password to change a menu item if
he or she returns to the menu mode within approximately 5 minutes.
Note
The change privilege thus refers to a temporary authorization to change menu items.
In contrast, the access privilege refers to a fundamental and configurable authorization
to change menu items at certain password levels.
