5.5.3 Using the ESC key
You can trigger two different functions by pressing the ESC key:
Firstly, you can cancel a commenced procedure, e.g.:
S
The input of a number
S
A calibration procedure with calibration gas
S
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 one level higher in
submenus (”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 .
In this manner, you enter the first submenu. 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.
