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) CO2. In an indoor environment,
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 CO2is an excellent indicator of the efficacy of the renewal of
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 (CO2);
Measurement of the ambient temperature;
Measurement of the relative humidity;
It works out air quality criteria based either on the level of CO2or on a combination of the three physical quantities measured.
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 CO2.

2. USE IN STAND-ALONE MODE
The instrument can operate in two modes:
•the stand-alone mode described in this section,
•the record mode, in which it is controlled by a PC. This mode is described in the next section.
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
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 or 3D, 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 CO2value; 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

8
It also has several functions that can be used in the various modes:
The MIN MAX function
The HOLD function
The M_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 CO2measurement 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 CO2and hygrothermal comfort zone.
The audible and/or visual warnings alert you to overshoots.
The level of CO2is measured every minute.
2.6.1 Activation of the 1D and 3D modes

2.6.2 Operation of the visible and audible warnings
1D mode: Activation of the visual (and, if activated, audible) warnings during overshoots of the CO2thresholds.
S1 = Low threshold = 1000 ppm
S2 = High threshold = 1700 ppm
Level of CO2< S1
Back-lighting off
Air quality indicator: good
S1 < Level of CO2< S2
Blinking orange back-lighting
Arrow indicating overshoot of the CO2threshold
Air quality indicator: average
The back-lighting is off in ECO mode
Level of CO2> S2
Blinking red back-lighting
Arrow indicating overshoot of the CO2threshold
Air quality indicator: poor
The back-lighting is off in ECO mode

10
3D mode: Activation of the visual (and, if activated, audible) warnings during overshoots of the temperature, humidity, and/or
CO2comfort zones.
Example of display with
no overshoot of the
CO2, temperature, and
humidity comfort zones
Back-lighting off
Optimum comfort zone indicator:
Example of display with
overshoot of the
temperature and
humidity thresholds
Blinking red back-lighting
Arrow in the direction of the overshoot for each quantity outside the comfort zone.
"Outside optimum comfort zone" indicator:
The back-lighting is off in ECO mode
For the 1D and 3D modes, if the buzzer is active, it will sound intermittently upon the appearance of the symbol.
The Porcher diagram defines the hygrothermal comfort zones:
Relative humidity (%RH)
Absolute humidity (g/kg)
Optimum comfort
zone
Dry-bulb temperature (°C)

11
2.7 ECO MODE (ENERGY SAVING)
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 CO2is measured only once every 10 minutes. This saves the batteries.
In addition, the device sets itself to sleep mode at night, from 4:30 p.m. to 8:30 a.m. These times can be programmed using the
Data Logger Transfer software provided with the device (see § 3).
In the ECO mode, the measurement is more sensitive to instantaneous variations of CO2. For example, if the user
breathes near the device, it may throw off the measurement. It will be necessary to wait for the next measurement to
recover the true concentration of CO2in 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.
To stop the function

12
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.
When the MIN MAX function is activated, recording of the minimum and of the maximum starts but the display of the three
quantities measured makes it possible to continue using the device normally.
To stop the MIN MAX function.

13
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 change modes.
2.12 BACK-LIGHTING FUNCTION
To activate and de-activate back-lighting.
The back-lighting switches itself off automatically after 10 seconds.
It is impossible to activate the back-lighting in the ECO mode.
To stop the
function
To stop

14
2.13 ACTIVATION OF THE AUDIBLE WARNING (BUZZER)
There is no buzzer if the ECO mode is active.
2.14 CHANGE OF UNIT OF TEMPERATURE
The choice of unit of temperature is preserved when the device is switched off.
2.15 DISPLAY OF ERRORS AND ANOMALIES OF OPERATION
2.15.1 OL symbol
The OL symbol appears on screen when the measurement leaves the range covered by the device. In other words when:
CO2> 5,000 ppm
-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.
First press the ECO key, then,
while keeping it pressed, press the
MODE key.
Repeat the operation.
