3. Change temperature compensation from automatic to manual and enter a manual compensation temperature
4. View diagnostic variables.
Level 2: A level 2 user can
1. Do everything a level 1 user can do
2. Change alarm setpoints
3. Rerange the 4-20 mA outputs
4. Manually test both outputs and all four alarm relays.
Level 3: A level 3 user has access to every menu item. Only a level 3 user can change passwords.

the main display. Entering the "lock all" password allows the user access to
all Level 1 functions.

access to all Level 2 functions.
Lock config: Entering the "lock config" password allows the user access to
all Level 3 functions.
The analyzer will accept a higher level security code at a lower level securi-
ty gate. For example, the analyzer will accept a level 2 password at a level 1
gate.
