Calibration
With these functions you can calibrate the zero and sensitivity of the analyzer using
calibration gas (see Calibration (Page 111) for menu structure).
Parameters
With these functions you can match the analyzer functions to your specific application, e.g.
by entering limits, measuring ranges, and time constants (see Parameter (Page 124) for
menu structure).
Configuration
With these functions you can define the assignments of the analyzer interfaces etc., e.g. the
assignments of relays and current outputs (see Configuration (Page 132) for menu
structure).
7.4.3.1 Code levels
The ULTRAMAT 23 is provided with two code levels to protect against unauthorized or
unintentional inputs. As soon as you call a function protected by a code for the first time, you
will be requested to enter the three-digit code.
With the introduction of firmware version 2.15.06, you can now use letters and special
characters for the code in addition to numbers.
Note
You should change the factory-set codes once you have become acquainted with operation
of the ULTRAMAT 23 (see section Configuration: Special functions: Changing the
codes/language (Page 143)).
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:
● The dialogs "Logbook/faults" and "Maintenance requests" in the menu "Analyzer status",
submenu "Status",
● the menu "Calibration" ,
and
● the menu "Parameters".
The following is protected by code level 2:
● The menu "Configuration".
Note
If the analyzer requests that you enter code level 1, you can enter the code for level 2
instead to release this level. Level 1 is then enabled simultaneously. Level 1 is automatically
enabled as soon as the higher code level 2 has been enabled.
