7.2 Measuring

√ | The instrument is switched on and is in the measurement view.
1 | Place the measuring instrument into the position in which the measurement is to be carried out.

IMPORTANT

• The probe contains sensitive visual components. Please handle the probe with care.
• Strong vibrations alter the factory calibration. Testing of measurement values at fresh air 350 to 450 ppm CO2 (urban air up to 700 ppm CO2).
• Avoid dew on the probe, otherwise long-term stability will be impaired. If there is dew on the probe, this can lead to higher CO2 measurement values.
• If the ambient temperature changes (change of measuring location, e.g. indoors/outdoors), the sensor/probe requires an acclimatization phase of a few minutes.
• After the measuring instrument is switched on, there is a sensor warm-up phase of approx. 30 s.
• The CO2 concentration in the sensor requires approx. 60 s to adjust to the environment. Gently waving the probe reduces the acclimatization time.
• Keep the probe as far away from your body as possible. This avoids any influences due to the CO2 content of the air you breathe.
