Executing calibration
Calibration*: In the “normal display view”, push and hold the
button for 10 seconds:
a. When the asterisk (*) in the upper right corner of the display
is lit, push the button shortly. Repeat this five times in a row
to enter the Calibration mode. For each correct push of the
button, a dot will be lit in the lower left corner. If an incorrect
push happens, the procedure starts over again. The reason
for this advanced way to enter the Calibration is to avoid
unintentional calibration.
b. If no further actions is performed for 1 minute, in Calibration
mode, the O2 Sensor will go back to Service Mode One.
c. The instructions in the display will say Push the button to
start the calibration. Push the button short and a 90 second
timer starts counting down. If the calibration is successful,
the display will show “Calibration OK” and go back to Service
Mode One, for 30 seconds, and then go to “normal view”.
If the display says “Calibration Error”, try to ventilate the room
more and make a new calibration. If the calibration still fails,
replace the O2-sensor.
* Calibration - Only to be performed by trained and certified service personnel.
