Operating instructions

Evaluation of the CO2-levels will be restricted to the most recent versi-

ons of our Logger-software only. Always check for the latest versions at

our website www.arexx.com/templogger.

Connect the power and activate the sensor with the on/off switch (5).

Check if the sensor number in question including the CO2 and tem-

perature value are present in the sensor list of the temperature logger

software.ThersttemperatureorCO2valuewillappearandapprox.

60 seconds later its counterpart value. With help of the settings button

(2), you can call the sensor data and the sensor number, the sensor

number scrolls onto the display.

After powering up the sensor, it can take a little time before the speci-

Calibrating

The GE CO2 module is self calibrating by means of the Automatic

Background Logic (‘ABC Logic’).

ABC Logic is a patented self calibrating technology which is developed

for an environment where the CO2 level reaches the regular value (ap-

prox. 400 ppm) at least three times during 14 days.

The ABC Logic algorithm starts working after 24 hours and then adjusts

its measurement result automatically.
