* This product and its measured values may not be used for professional applications or to inform the public.

5. Getting started
The product can be used both in battery and mains operation. For battery operation, fully charge the product once before first use.
5.1 Battery operation
Warning – rechargeable battery
* Only use suitable charging devices or USB connections to charge the product.
* Do not use defective chargers or USB ports and do not attempt to repair them.
Warning – rechargeable battery
* Do not overcharge the product or allow the battery to completely discharge.
* Avoid storing, charging and using in extreme temperatures and at extremely low atmospheric pressures (such as at high altitudes).
* Charge regularly (at least quarterly) during periods of prolonged storage.
5.2 Mains operation
Connect the supplied micro-USB charging cable to the micro-USB port (D) on the product. Connect the free plug on the micro-USB charging cable to a suitable USB charger. To do this, consult the operating instructions for the USB charger you are using.
* The battery indicator (3) indicates the charge level by means of the bars.
* When fully charged, the charging process can be terminated. Disconnect the product from the mains.
Note – charging process
* A complete charging cycle takes about 2 hours.
* The product's battery can be charged both when it is switched on and off.
* When fully charged, the maximum operating time is approx. 180 to 210 minutes.
5.3 Switching on/off
* Remove the protective film from the display.
* Press and hold POWER (A) for approximately 3 seconds to switch the product on.
* With each switch-on, a countdown of 180 seconds begins. This is the time required to pre-heat the internal CO2 sensor. The display (4) counts backwards from 180.

It is normal for the device to heat up while charging and during operation since the CO2 sensor is heated in order to be able to work accurately. If there is an inadequate circulation of air, the device's own warming can cause the temperature display to differ. The ventilation opening must never be covered up. This would lead to overheating / destruction of the device and to incorrect CO2 measurements.

6. Air quality guidelines (AQI)
CO2 ppm / AQI
0 - 450 / 01 Good
451 - 1000 / 02 Moderate
1001 - 1500 / 03 Unhealthy for sensitive people
1501 - 2000 / 04 Unhealthy
2001 - 3000 / 05 Very unhealthy
3001 - 5000 / 06 Endangering health

In addition to the digital display of the CO2 concentration (4), the device also has a CO2 traffic light (5). It offers a visual quick check. From 400 to 700 ppm, GOOD lights up green; from 701 to 1000 ppm, NORMAL lights up yellow; from 1001 to 5000 ppm, POOR lights up red. Above 1001 ~ 2,000 ppm, the alarm symbol starts to flash and a repeated alarm sound is heard twice in succession which becomes more intensive when the limit of 2,000 ppm is exceeded. The alarm symbol and the ppm indicator flash. This can be switched on and off using the POWER button (A). Check via the symbol (1) in the display.
Specifically by providing the value for the CO2 concentration in the air (4), conclusions can be drawn about aerosols with viruses (e.g. Covid 19) present in the air. Although these are not directly detectable, increased CO2 pollution is at the same time a measure of virus-contaminated air. This can be remedied by regular airing. Permanently inhaling bad and stale air can cause tiredness, headaches, eye irritation, etc. The ability to perform and concentrate decreases noticeably as a result.

7. Functions of the + and M buttons
* Press the + button (B) to check the max / min measured values. Holding the + button (B) for longer permanently deletes all of the measurements made so far.
* Pressing the M button allows the temperature display to be toggled between Celsius and Fahrenheit.

8. Recalibration of the product
* Press and hold the + (B) and POWER (A) buttons simultaneously for approximately 3 seconds to recalibrate the product. Always carry out this calibration at the commissioning stage and after prolonged periods of non-use.
* Calibration should be carried out outdoors for around 20 minutes, as CO2 levels here are usually around 400-450ppm.
* Please ensure that there is no CO2 source in the immediate vicinity. Avoid direct sunlight and rain.
* CO2 is detected after calibration. Please try to avoid perfumes, paints, air fresheners, cigarette smoke, alcohol, chemical substances and so on while carrying out measurements since these can lead to incorrect measuring results.

9. Care and maintenance
Note
Disconnect the device from the mains before cleaning and during prolonged periods of non-use.
* Only clean this product with a slightly damp, lint-free cloth and do not use aggressive cleaning agents.
* Ensure that no water is able to enter the product.

10. Warranty Disclaimer
The measuring device must not be used as a warning device for dangerously high concentrations (e.g. industrial safety monitoring). It is not suitable for medical institutions, certification or test measurements. The measuring device is primarily used for testing purposes and for orientation in private households. No liability is accepted for possible damage in case of malfunction.
It is not possible to transfer data via the USB cable. Hama GmbH & Co KG assumes no liability and provides no warranty for damage resulting from improper installation/mounting, improper use of the product or from failure to observe the operating instructions and/or safety notes.

Udmærket lille manual til en luftkvalitetsmåler. Manualen fraskriver dimsen enhver nytte som dokumentation for noget og der er heller ikke hjælp at hente hvis man har gjort en ulykke på sig selv på grund af noget tal, den har vist.

I praksis virker den fint som advarsel mod hengemt luft. Der er et lille 750 mAh batteri i, så man kan flytte dimsen rundt fra stikkontakt til stikkontakt, men uden strøm holder den kun i ca 3 timer.
Udfra det kan man gætte at den nok trækker ca 0,25 W i almindeligt brug.

Den kallibreres ved at tænde den udenfor og lade den stå i ca 20 minutter, hvorefter den regner med at co2 niveauet er ca 400 ppm. Under brug skal man nok trække en grad eller to fra den viste temperatur for luftkvalitetsmåleren laver lidt varme, når den kører.

CO2 ppm / AQI
0 - 450 / 01 Good
451 - 1000 / 02 Moderate
1001 - 1500 / 03 Unhealthy for sensitive people
1501 - 2000 / 04 Unhealthy
2001 - 3000 / 05 Very unhealthy
3001 - 5000 / 06 Endangering health

Den er fin som fingerpeg til om det er frisk luft eller frisk kaffe, der mangler. CO er en helt anden snak. CO niveau skal helst være godt under 35 ppm og over 800 ppm dør man af efter et stykke tid. 12000 ppm slår folk ihjel på få minutter.
Udåndingsluft har mellem 4 og 5 % CO2, dvs ca 45000 ppm CO2, så i små rum bliver det hurtigt et problem.… (mehr)

Ret lige ud ad landevejen forklaring til en vejrstation med en udemåler og en indestation.
Den bruger DCF = Deutschland - langbølge - Frankenfurt - tidssignalet.

Denne model bruger Channel 1 fast på udedelen. Skift batteri på udedel først og så på indedelen og vent 5 minutter på at den kommer helt til sig selv og får fat i tidssignalet fra Frankfurt.

Ved skift til og fra sommertid er det nemmest at pille batteriet ud og sætte det ind igen og lade stationen selv finde tiden igen.… (mehr)
