4.2.3 Calibration of CO2 sensor (installed as CO2 sensor)
The CO2 sensor should be checked between each batch when the house is in
Empty house
.
If the CO2 sensor is installed as an auxiliary sensor (for emission measurement), it must be calibrated as de-
scribed in the section
Calibration of CO2 sensor (installed as auxiliary sensor) [ } 24] .
1. Replace the air in the house in
Empty house
mode by running with 100% exhaust and 100% open inlets for
at least 20 minutes.
The reading of the CO2 level should now be 500 ppm +/- 100 ppm or the same value as the atmospheric air
+/- 100 ppm.
2. Check if the reading deviates more than +/- 100 ppm from 500 ppm (or from the same value as the atmo-
spheric air value).
If the reading deviates more than +/- 250 ppm, the sensor should be replaced.
Offset calibration of CO2 sensor
The sensor can only be calibrated when there are no animals in the house and it has been thoroughly venti-
lated.
Calibration should always be carried out in relation to atmospheric air and not in relation to other types of CO2
sensors.
See the menu

.
1. Adjust the Calibration offset until the read CO2 value shows 500 ppm.
The other values must not be changed.
Value Factory reset
Calibration offset CO2 0 ppm
Minimum voltage 0 V
Maximum voltage 10 V
Minimum value 0 ppm
Maximum value 10000 ppm
Note: Calibration should only be carried out only by staff trained by SKOV.
4.2.4 Calibration of CO2 sensor (installed as auxiliary sensor)
DOL 19 and DOL 119 CO2 sensor should be checked between each batch when the house is in
Empty house
.
If the CO2 sensor is installed as a CO2 sensor (for adjustment of ventilation), it must be calibrated as described
in the section
Calibration of CO2 sensor (installed as CO2 sensor) [
}
24] .
1. Replace the air in the house in
Empty house
mode by running with 100% exhaust and 100% open inlets for
at least 20 minutes.
The reading of the CO2 level should now be 500 ppm +/- 100 ppm or the same value as the atmospheric air
+/- 100 ppm.
2. Check if the reading deviates more than +/- 100 ppm from 500 ppm (or from the same value as the atmo-
spheric air value).
If the reading deviates more than +/- 250 ppm, the sensor should be replaced.
Calibration of CO2 sensor via Minimum value
The sensor can only be calibrated when there are no animals in the house and it has been thoroughly venti-
lated.
