You can calibrate the zero and sensitivity of the analyzer using
calibration gas (see Fig. 5-5 for menu structure).
You can match the analyzer functions to your specific application, e.g.
by entering limits, measuring ranges and time constants (see Fig. 5-6
for menu structure).
You can define the assignments of the analyzer interfaces etc., e.g. the
assignments of relays and current outputs (see Fig. 5-9 for menu
structure).
The ULTRAMAT 23 is provided with two code levels to protect against
unauthorized or unintentional inputs. As soon as you call a protected
function for the first time, you will be requested to enter the defined
three-digit code number.
Notice
You should change the codes once you have become acquainted with
operation of the ULTRAMAT 23 (see Section 5.10.2.1).
The lowest code level (level 1) is factory-set to "111", and the higher
level (level 2) to "222".
The following are protected by code level 1:
S
The dialogs "Logbook/faults" and "Maintenance requests" in the
menu "Analyzer status", submenu "Status",
S
the menu "Calibration" and
S
the menu "Parameters".
The following is protected by code level 2:
S
The menu "Configuration".
Notice
If the analyzer requests you to enter code level 1, you can enter level 2
instead. Level 1 is then enabled simultaneously. Level 1 is
automatically enabled as soon as the higher code level 2 has been
enabled.
