Charging the internal battery can be performed:
• Either with the supplied power (the Cairsens continues to measure normally during this phase).
• Either from the USB port of a computer (the Cairsens measure continues normally during this phase).
The battery of Cairsens is initially charged charged to 100% at the factory, however, a natural discharge can occur and be recognized upon
delivery.
Upon receipt, it is asked to recharge it completely, in order to benefit from 3 months of shelf storage without use
. By the way, thank
you for not forgetting to reconnect the red dongle from this moment
The charge level is given by the icon "battery" whose filling is the real autonomy as illustrated by the following table:

The optimal charging time is 4 hours, a full charge every 24 hours (8 hours for COVNM sensors) is recommended.
Commissioning
The Cairsens commissioning is done by removing the red dongle Mini USB connector. The screen displays 'StArt' (see photo
below).
No prior adjustment is necessary, at the inception of the function begins Cairsens measures, automatically will be
stored and displayed on the screen.
The memorizing of the measures is done continuously in internal memory of Cairsens.
Measures are exploitable in graphical format and / or in .XLSX file on computer with the software CAIRSOFT V4.5
(and more).
Calibration and measurement of Cairsens are guaranteed and certified for 12 months after delivery.
Measurement made by the sensor:
The measurements displayed on the screen are made as follows:
• Moving average of several sensor readings within one minute.
• This value is stored in memory.
• Refresh this value on the screen every 10 seconds.
The frequency measurements may be either (using Cairsoft) for 1 minute, 15 minutes
or 1 hour.
Warning, this parameter directly affects the amount of storable data and storage
duration (see "Download of the measures").
The sample conditionning is ensured by the filter, an essential component for the proper functioning of Cairsens and must be handled with
care.
Humidity and temperature readings:
The Cairsens measure the temperature and relative humidity and stores them at the same frequency as that chosen for the measurement
of the concentration of the individual pollutant:
Temperature [T °C ] of the air sample is expressed in ° C.
Relative humidity [RH%] of the air sample is expressed in%.
These two statements are included in the same table that measurement of the pollutant, with downloadable Cairsoft.
Metering and monitoring the autonomy of Cairsens:
The Cairsens measure the battery voltage [Bat (mV)] and store it at the same frequency as that chosen for the measurement of the
concentration of pollutant. This measurement is transcribed as follows:
• Bat (mV) = 4700 mV: the Cairsens is charging / connected to a power supply.
• 4200 <Bat (mV) <3300 mV: Normal use of Cairsens on battery only.
The Bat measures (mv) are integrated in the same table that measures the concentration of pollutant, with downloadable Cairsoft. The
[battery] logo on the LCD screen also allows to follow this trend (see "Power supply and Charging" chapter).
Time, date and time stamping of measured data:
The internal clock is factory set. Before use or measurement campaign, check its setting.
The loss of autonomy can alter the timestamp (see Table 1 above), the Cairsens record the date and time
of last analyzed sample.
At reboot:
The display indicates the Cairsens alert 'dAtE' 'with a lower 3 LED flashing every 5 seconds (see
photo cons).
Proceed to set the time and date using the Cairsoft software. Once the adjustment, the time
stamp measurements will resume from the new date and time.
If the setting is not made, the measures will be stamped from 01/01/2030.
Manual control of startup and shutdown steps:
The Cairsens is, by default, continuous measurement mode. Dongles provided allow you to change this feature manually:
The Red dongle:
o
Inserted: The Cairsens is in "sleep" mode. No action is made; the fan and display are turned off. Use
during storage or prolonged Cairsens of non-use.
o
Removed: The display shows' 'StArt' (see "commissioning"), the measure in continuous mode resumes.
The Green dongle:
o
Inserted: Enables the use of Cairsens on a flat surface (eg a desktop) without closing the inlet sample.
Also provides protection from the USB port while using the Cairsens.
o
Removed: no action.
