5.4.2 Access Levels
Access levels can be used to prevent changes
to parameters by unauthorised personnel.
The X-STREAM menu system supports four
prioritized access levels which can be acti-
vated and deactivated separately, and should
be supplied with their own access codes.
Level four has the highest priority and is
used for factory settings — only qualied
EMERSON service personnel have access
to this level.
Level three allows access to system admin
parameters, e.g. for data capture and proces-
sing systems.
Level two covers the expert settings, e.g.
basic settings for calibration.
Level one is the user level and includes
parameters which should be set by trained
personnel.
Any menus not assigned to one of these levels
are not editable or are of minor relevance.
In this chapter, the descriptions of the indi-
vidual menus also indicate which level the
menus are in. These assignments cannot be
changed.
Access codes for levels 1 to 3 can be de-
ned, activated and deactivated by the client.
The analyzer is delivered with the following
settings:
Level Access code Status
1 00000001 Off
2 00000002 Off
3 00000003 Off
Note!
If a lower level is locked (i.e. its code acti-
vated), all higher levels will also be locked.
If a higher level is unlocked (i.e. its code
deactivated), all lower levels will also be au-
tomatically unlocked.

any parameter will only effect this one chan-
nel.
A multi-channel analyzer requires that a
channel must be selected before its parame-
ters can be changed. When this selection is
necessary, a menu is automatically displayed;
