F-Gas Detector Instructions
Now, the user is able to set the desired concentration value of the output signal by using the
UP and DOWN keys. For this, the relevant set value can be monitored live at the analogue
output.
Pressing the UP or DOWN keys for longer will lead to an auto-repeat. This feature is helpful
for the adjustment for a larger range.
It is possible to exit the SPAN-calibration at any time by pressing SPAN for 3 seconds.
Keep SPAN pressed for 3 seconds.
If the action was successful, the STATUS-LED will change from flashing yellow to flashing
green for 3 seconds, subsequently changing to lighting up yellow (one is still in level 1 of
maintenance mode and is still able to carry out system changes.
In the case of an error in connection with the SPAN-calibration, the STATUS-LED will
change from flashing yellow to flashing red for 3 seconds, subsequently changing to a
steady yellow (one is still in level 1 of maintenance mode). The changed calibration values
were not taken over. This process has to be repeated.
Caution
: The changes only become effective when the maintenance mode has been exited
as described in chapter 4.7. Without this process, for instance when severing the operating
voltage, all changes will be lost.
