7.3.3 Key assignments
Eight keys are available for operating the ULTRAMAT 23. These keys have the following
meanings:
No. Designation Description Function
1* MEAS Measure Measure; abort input operations;
leave input mode (from any menu level);
switch from input mode to measuring mode and
code analyzer again
2 CAL AUTOCAL Automatic calibration: activation of calibration with ambient air or nitrogen
3* PUMP Pump Switch internal sample gas pump on/off
4 ESC Escape In input mode: return by one menu level or cancel current input or cancel calibration*
5 ↑ Up arrow Increase selected digit;
select previous menu item
6 ↓ Down arrow Reduce selected digit;
select next menu item
7 → Right arrow Move input cursor by one position to right (cyclic, i.e. the cursor is set to the left edge
when the right edge has been reached)
8 ENTER Enter In measuring mode: switch over to input mode;
in input mode: import entered parameters or
call a menu item
* The input is suppressed if certain conditions are fulfilled.
A corresponding message is then output briefly on the display.
You can use the arrow keys to modify numerical values by increasing or decreasing the digit
at which the cursor is located. The digits are modified continuously, i.e. 0 follows again after
digit 9. You can also decrement to 9, 8... following digit 0. The analyzer outputs the value
FFF... if incorrect numbers are entered.
Use of the <MEAS>, <ESC>, and <ENTER> keys is described using examples in section
Key operations step by step (Page 98). Use of the <CAL> key is described in section The
CAL key (Page 101), use of the <PUMP> key in section The PUMP key (Page 102).
7.4 Operating modes
During operation, the analyzer is always in one of following operating modes:
● In the warm-up phase (see section Warm-up phase (Page 95))
● In measuring mode (see section Measuring mode (Page 96))
● In input mode (see section Input mode (Page 96))
