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 pass-
word.
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 7-C-4).
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 authori-
zation to change menu items at certain password levels.
Changing the
Password
Changing the password is described in Chapter 7 “Gas Analyzer Configuration”.
