Measurement Basics
6.1 NDIR CO2 sensor
IR radiation source
6.1.1 Explanation
The sensors are based on non-dispersive infrared sensor technology, NDIR. This
is the most widely used sensor technology for CO2 measurement. The principle
of the NDIR sensor is that an IR light source is focusses so that an optical
beam is created, which passes through the existing gas, including CO2. After
an optical band pass filter is passed, an IR sensor measures the level of IR
light, wherein the CO2 values in the optical path are displayed.

detector
IR detectors
A sensor module with single-channel detectors is used for the product. A micro
light bulb is used as an IR radiation source. It emits a broadband spectrum.
The sensor is long-lasting and maintenance-free. In order to be able to
maintain the specified accuracy for many years to come, regular adjustment
must be carried out depending on the required accuracy.

7.3 CO2 adjustment
In order to improve the accuracy, the carbon dioxide sensor can be adjusted.
In order to conduct a CO2 adjustment, proceed as follows.
1-point adjustment
Used for optimisation of the accuracy at the adjustment point. The best
possible accuracy can be achieved even with elevated CO2 concentrations
2-point adjustment
Used for optimisation of the accuracy for extreme requirements over a wide
measuring range beginning from 0 ppm.
Basic sensor adjustment
Used to reset the sensor in case of deviations beyond the normally expected
deviations. The values of all prior adjustments are reset and cannot be
restored. A plausibility check of the carbon dioxide concentrations does not
take place. Depending on the setting, adjustment to 0 ppm CO2 test gas or
fresh outside air can take place. Ensure that the setting of the gradient
compensation setpoint [.SL was entered correctly in the Expanded settings
menu.
If reliable values can no longer be displayed, we recommend performing basic
sensor adjustment of the zero point at 0 ppm CO2 with nitrogen and a possibly
necessary additional gradient compensation via 1-point adjustment.
If incorrect values are displayed after the adjustment, e.g. ERR.2 at 0 ppm
CO2, the adjsutment must be repeated.
NOTE
Adjustment can be carried out in clean ambient air or with test gases
(optionally available gas extraction device recommended). 1-point adjustment
at any arbitrary point above 350 ppm and 2-point adjustment at 0 ppm and an
arbitrary point above 350 ppm are both possible.
For automatic adjustment, open the Adjustment menu.
The product is switched on.
Clean ambient air or test gas for gradient correction
Test gas 0 ppm CO2 for zero point adjustment for 2-point adjustment or basic
sensor adjustment at 0 ppm

1. If you would like to perform a adjustment with test gas, connect the
extraction device to the product first.
2. Press the Function key for 4 seconds to start the adjustment. [ONF appears
in the display first, then [AL.
3. 1-point, 2-point or basic sensor adjustment is started. This depends on
what was adjusted in the Expanded settings menu.
1-point adjustment 1. [.SL appears in the display for 1-point adjustment. 2.
The product determines a stable value first. If the measured value is outside
of the
value range integrated in the product, the display flashes briefly and an
acoustic signal is issued every 10 s. 3. If a stable correct value is reached,
the display flashes briefly, an acoustic signal sounds and the bar indicator
blinks. 4. You can change the value of the gradient compensation with the up
key and down key. Otherwise, confirm the preadjusted value with the function
key. The 1-point adjustment is finished.
2-point adjustment 1. [.OF appears in the display for 2-point adjustment. 2.
Allow the test gas to flow at about 0.5 l/min at 0 ppm of CO2. The product
deter-
mines a stable value first. If the measured value is outside of the value
range integrated in the product, the display flashes briefly and an acoustic
signal is issued every 10 s. 3. If a stable correct value is reached, the
display flashes briefly, an acoustic signal sounds and the bar indicator
blinks. [.SL appears in the display. 4. Remove the test gas and connect a
second test gas to the extraction device. The product determines a stable
value first. If the measured value is outside of the value range integrated in
the product, the display flashes briefly and an acoustic signal is issued
every 10 s.

5. If the display flashes briefly, an acoustic signal sounds and the bar
display blinks, a stable correct value has been achieved.
6. You can change the value of the gradient compensation with the up key and
down key. Otherwise, confirm the preadjusted value with the function key.
Remove the extraction device. The 2-point adjustment is finished
Basic sensor adjustment
1. KARD appears in the display for basic sensor adjustment.
2. Depending on the specification [.SL, let the test gas with 0 ppm CO2 flow
in at approx. 0.5 l/Min or move the product into clean ambient are with 400
ppm CO2. The product determines a stable value first. If the displayed
measurement is outside of the measuring range of the sensor, the product
cannot perform stability recognition. It must be ensured that the carbon
dioxide concentration at the sensor is stable before the adjustment is
started.
3. If a stable correct value is reached, the display flashes briefly, an
acoustic signal sounds and the bar indicator blinks.
4. Remove the extraction device, if applicable.
NOTE
Current test gases normally have accuracies of ± 2 %. This tolerance must be
taken into consideration with the measurement uncertainty. The specifications
on the analysis certificate must always be observed.
Outcome of an action
NOTE
For information about the available adjustment settings, refer to Configuring
parameters of the configuration menu [ 13].
After the adjustment is finished [AL DONE is displayed. Then, the current
measurement is shown in the display again.
If the adjustment is not completed successfully an error message is displayed.
[AL ERR. appears in the display. See Error and system messages [ 24]. Confirm
the error message pressing the Function key. The product restarts. The values
of the last correctly performed adjustment are restored. Configure parameters
of the expanded settings menu [ 16]
