1. PRESENTATION
1.1 INTRODUCTION
Carbon dioxide is a colourless and odourless gas. It is not toxic, but at high concentrations can interfere with mental
concentration and cause headaches. Outdoor air contains approximately 0.04% (400 ppm) CO
human activity (breathing) can rapidly increase this concentration to values in excess of 1000 ppm (for example in meeting
rooms or school classrooms). It is for this reason that the level of CO
indoor air.
The ambient temperature and relative humidity are two more important quantities in the monitoring of indoor air quality. Beyond
certain values, they can cause discomfort and favour the propagation of moulds that release allergenic or irritant substances
into the air.
The C.A 1510 is an instrument for measuring physical quantities that combines the following functions:
Measurement of the concentration of carbon dioxide in the air (CO
is an excellent indicator of the efficacy of the renewal of
2
);
2
Measurement of the ambient temperature;
Measurement of the relative humidity;
It works out air quality criteria based either on the level of CO
The device is a response to decree no. 2012-14 of 5 January 2012 concerning the evaluation of means of ventilation and the
measurement of pollutants in the context of measurements of CO
or on a combination of the three physical quantities meas ur ed.

2.1 INSTALLING THE BATTERIES
See §5.2.
2.2 SWITCHING THE DEVICE ON
2.3 SWITCHING THE DEVICE OFF
2.3.1 Manual switching off
2. USE
Manual switching off is blocked if a programmed recording session (P_REC) is in progress.
2.3.2 Automatic switching off
In the portable mode, the device switches itself off automatically after 15 minutes of inactivity.
Automatic switching off is de-activated in the other modes (1D or3D, ECO, P_REC), and in the MIN MAX and M_REC
functions, if the Bluetooth or USB link is active or if the device is connected via the USB mains adapter.
2.4 MAKING A MEASUREMENT
When the device is switched on, CO2 is displayed during the wait for the first measured of CO2 value; access to the keys is
disabled until this first value is displayed on screen. The measurements are then displayed automatically on screen.
If the device is exposed to large variations of temperature, after the temperature stabilizes, wait 20 minutes before
starting the measurements.
The device has 4 operating modes:
The portable mode,
The 1D and 3D modes
The ECO mode
The P_REC mode
It also has several functions that can be used in the various modes:
The MIN MAX function
The HOLD function
TheM_REC function
The backlighting function

2.5 PORTABLE MODE
The portable mode is the mode the device starts up in. It is in this mode that the device makes the most measurements: one
every 15 seconds. It is therefore highly responsive to changes in air quality.
This mode is used to inspect several rooms one after another. Install the device in a room and wait for the CO
measurement

to stabilize (approximately 10 minutes).
2.6 1D AND 3D SURVEILLANCE MODES
1D mode: surveillance of the level of CO2.
3D mode: surveillance of 3 parameters: level of CO
and hygrothermal comfort zone.

The audible and/or visual warnings alert you to overshoots.
The level of CO2 is measured every minute.

The ECO mode is used when the device is left to measure the air quality in a room over a longer period.
The backlighting and the buzzer are deactivated, and CO

In the ECO mode, the measurement is more sensitive to instantaneous variations of CO

recover the true concentration of CO2 in the room.

2.8 P_REC MODE (PROGRAMMED RECORDING)
When the device is connected to a PC, you can program a recording session (see §3). There are two types of programmed
recording sessions:
Locked recording, in which the device displays nothing except the P_REC symbol (blinking before recording starts, then
steady while recording) and the keys are inactive.
At the end of recording, the device switches itself off.
Unlocked recording, in which the device displays the measurements. The P_REC symbol is displayed, blinking before
recording starts, then steady while recording. The device operates normally. It is not possible to change the mode, but the
MIN MAX, HOLD and backlighting functions can be used.
Pressing the button has no effect.

2.9 MIN MAX FUNCTION
This function displays the maximum and minimum measured values in addition to the current value: the device compares each
new measurement to those displayed. If the new measurement is greater than the former MAX value or less than the former
MIN value, it replaces them in the display.
The MIN MAX function cannot be used in the 1D and 3D modes.

2.10 HOLD FUNCTION (HOLDING THE MEASUREMENT)
Pressing HOLD freezes the digital display on the last measurement displayed. Activating the function does not entail
interruption of recording or of the current mode, but access to the other functions of the device is disabled.
2.11 M_REC FUNCTION (MANUAL RECORDING)
You can start recording manually and all data measured are recorded in the device at the rate determined by the mode in
progress (see the table in § 4.3).
It is possible to record manually whatever mode is in progress (except P_REC). But once recording is in progress, it is no
longer possible to cha nge modes.

-10 °C < T < 60°C
5%< RH < 95%
2.15.2 Err symbol
If an error of the Err type is displayed, switch the device off and back on. If the error persists, the device must be sent in for
repair (see § 5.4).
2.15.3 MEM_FULL Symbol
When the memory is full, the MEM_FULL symbol appears on screen.
Any recording in progress is then stopped, and it is impossible to restart recording before emptying the memory.
