5. Commissioning

Remove the product from the packaging and remove all packaging material. Connect the mains adapter supplied with the device to a properly connected socket. If you want to use the device in battery mode, fully charge the device first.

Press the „MAX/MIN“ and „ALERTS“ buttons to switch the device on or off. A 150-second countdown appears on the screen, indicating that the CO₂ sensor is being initialised. The CO₂ values are then shown on the display.

When using the charging cable, the battery inside the device is charged. If the power supply is interrupted, the device switches to battery operation or it can be operated directly with the built-in battery.

5.1 Battery

You can check the battery status on the display at any time by looking at the battery status symbol.

The battery symbol is displayed continuously while the battery is charging. When the battery is fully charged, the symbol is fully displayed.

6. Time and alarm setting

Press and hold the „MODE“ button for approx. 3 seconds to call up the time setting.

1. The 12/24 hour display starts to flash. Press the „UP“ or „DOWN“ button to set.

2. Press the „MODE“ button to confirm the entry. The hour then flashes. Set the current hour and press the „MODE“ button again to confirm.

3. Repeat the process with the minute display.
4. Then set the alarm time, starting with the hour. Then press the „MODE“ button to confirm the entry.
5. Repeat the process with the minute display.

Press the „UP“ button to deactivate the alarm and stop the alarm clock immediately. AL--“ appears on the display.

7. Minimum and maximum values for temperature and humidity

Press the „MAX/MIN“ button to display the display between the minimum and maximum measured value. The display cycle is: Maximum → Minimum → Return to normal display mode.

If you press and hold the „MAX/MIN“ button for approx. 3 seconds while the maximum and minimum values are displayed, you can delete the maximum and minimum values and restart the recording.

8. Calibration of the CO_2 concentration

Due to transport, vibration, ageing and other reasons, the detection accuracy of the sensor may be reduced. Deviations are corrected by calibration. The device has an automatic and a manual calibration option. It is recommended to use the automatic calibration. Alternatively, you can carry out manual calibration. Both methods are described below.

8.1 Automatic calibration

After commissioning, the device calibrates itself automatically for 150 seconds.

Make sure that during this time the sensor is in an environment where the atmospheric level is approximately the same as outdoors (approx. 400 ppm).

The automatic calibration function is suitable for office, home and other non-weather environments. It is not suitable for agricultural greenhouses, farms, warehouses and other locations.

8.2 Manual calibration of the CO_2 concentration

During calibration, the product must be positioned in an environment with a CO_2 concentration equal to the outside air (approx. 400 ppm) to ensure that the CO_2 concentration in the environment is stable.

In normal display mode, press and hold the „DOWN“ button for 3 seconds to enter manual calibration mode. „CAL“ flashes on the display. At this point, you can press the „DOWN“ button to exit the calibration mode.

The duration of the manual calibration is approximately 30 minutes.

9. Carbon dioxide alarm

Press the „ALERTS“ button to switch the carbon dioxide alarm function on or off. The display will show „CO2-ALERTS“ as soon as the alarm function is activated. Press and hold the „ALERTS“ button for 3 seconds to call up the setting for the CO₂ concentration alarm. The value of the maximum CO₂ concentration flashes. Press the „UP“ or „DOWN“ button to set the desired value.

Press the „ALERTS“ button to confirm the setting. The CO_2 concentration for the minimum alarm then flashes. Select this and confirm again with the „ALERTS“ button.

As soon as the alarm function is activated, the device will emit the alarm tone at the maximum and minimum CO_2 concentration.

If the alarm function is not activated and the value of the respective alarm is exceeded, either „Lo“ or „Hi“ flashes. However, the alarm tone is only emitted if the alarm function is activated via the „ALERTS“ button and the CO_2 concentration exceeds the set maximum concentration.
