Once you have carried out the above sequence on the analyzer, you are already acquainted
with the important points for operation of the ULTRAMAT 23.
7.4.3.3 The ESC key
You can trigger two different functions by pressing the <ESC> key:
● Firstly, you can cancel a commenced procedure, e.g.:
–
The input of a number
– A calibration procedure with calibration gas
– Any function if a fault occurs, e.g. if the flow of sample gas to the analyzer is missing.
● Secondly, you can use the <ESC> key to move to the next higher level in menu structure
("scroll back"). This procedure is the opposite to selection of a submenu using the
<ENTER> key ("scroll forwards"). If you repeatedly press the <ESC> key, you return back
to the main menu step-by-step. If you press the <ESC> key again in the main menu, the
analyzer switches over from input to measuring mode. All inputs are imported at the
same time. However, you will not be asked to confirm the inputs.
An example will clarify this:
The analyzer is in measuring mode and is uncoded.
Switch from measuring mode to input mode using
<ENTER>, select the menu item "Parameters" using the
< ↑ > or < ↓ > key, and press <ENTER> to confirm.
In this manner, you enter the first submenu.
Now press <ESC> and then
<ENTER> again. You have returned by one level and then
moved forwards by one level again; you are therefore in the
same menu again.
Press the <ESC> key twice, you are back in measuring
mode again.
7.4.3.4 The CAL key
If the analyzer is in measuring mode, pressing the <CAL> key triggers a single, automatic
calibration with ambient air or nitrogen (AUTOCAL).
