PRECAUTIONS FOR USE
If this device is damaged or a part is missing, please contact the dealer
immediately.
The protection provided by the device may be compromised if it is used in a way
not specified by the manufacturer.
Apply the safety tips listed below:
•Do not aim the LASER beam towards eyes.
•Do not place the thermometer on, or in proximity to, objects whose
temperature is > 65°C/150°F.
•If the thermometer is subjected to great variations in ambient temperature,
wait for 30 minutes after this becomes stable again before continuing with
measurement, so as to attain the specified accuracy.
•Let condensation, which can build up on the lens of the thermometer’s
measurement aperture, dissipate before continuing with measurement.
•Do not subject the thermometer to strong electric or magnetic fields (e.g.:
inductive heating, arc welding equipment…) that could induce errors in
measurement.
•Respect the climatic environmental conditions
•Keep the lens perfectly clean.

1. PRESENTATION
The C.A 1864 and C.A 1866 infrared thermometers are for the remote
measurement of the temperature of most materials without physical contact, with
an emissivity coefficient situated between 0.1 and 1.
They can also measure the temperature of polished metal surfaces after treatment
(marking with opaque labels or mat spray paint) to limit the "mirror" reflexion effect
of stray infrared ray interference. This treatment brings the emissivity coefficient to
above 0.1 which ensures correct measurement. An emissivity table gives the
emissivity ranges of a wide range of materials.
To measure a body’s temperature, simply point the probe at its surface. The
temperature displayed on the digital screen depends on the measurement
parameter selected and on the emissivity chosen (according to material). The
thermometer automatically switches off after 10 seconds.
2. FUNCTIONING - EMISSIVITY
All objects above absolute zero (-273.15°C) give out infrared energy. This radiated
energy is emitted in all directions at the speed of light.
The instrument’s lens picks up this energy and focuses it on an infrared detector.
This detector gives a voltage signal proportional to the quantity of energy received
and hence proportional to the temperature of the object.
Some objects not only give out infrared energy, but also reflect it as well. Unlike
matt surfaces, brilliant or highly polished surfaces tend to reflect energy. This
possible reflection is represented by a factor known as the emissivity, and can vary
between 0.1 for a highly reflective surface, and 1 for a black body.
In the case of the C.A 1864 and C.A 1866 thermometers, the emissivity can be
adjusted from 0.1 to 1, the value of which is determined depending on the material
of the body or surface to be measured.
These thermometers are suited to measurements on varnished, anodised or
oxidised surfaces, but taking into account their spectrum, shorter wavelength
instruments are better adapted to measurements of brilliant surfaces. (see §
Emissivity table).
To have a precise measurement, keep your thermometer perpendicularly to the
target.

4. USE
Never aim the LASER beam towards eyes.
4.1 PROCEDURE
1. Press the black trigger, all screen segments are displayed and the instrument
carries out a measurement as set-up before it was last switched off. SCAN
appeared on the screen. The HOLD symbol is displayed when you release the
trigger and the main display holds the measurement until the automatic
switch-off of the instrument after 10 seconds
2. Press the trigger once more and set up the measurement parameters using
the MODE button and possibly the buttons (see § 4.4).
3. Activate or deactivate the LASER sight and backlighting.
4. Aim the thermometer whilst pressing the trigger, using the LASER sight or
otherwise, at the target to be measured (see § 4.2 and 4.3).
Note:
The instrument memorises the last measurement set-up when switched off,
but not the last measurement.
If the trigger is held down, the instrument measures continuously.
4.2 MEASUREMENT PRECAUTIONS
•If the surface to be measured is frosted over or covered in other particles,
if possible clean the surface so that it shows through and program in the
corresponding emissivity value (see § 4.4).
•If the thermometer seems to give incorrect results, check the condition of
the measurement lens for condensation or other particles that could be
obstructing it. The lens should be cleaned carefully following the
instructions in § 6.3.

4.3 « TARGET DISTANCE / MEASUREMENT FIELD DIAMETER »
RATIO
This ratio, also known as the field of vision, indicates the diameter of the probes’
measurement field at a given distance from the target (see figure below).
In the case of a measurement point of small dimensions, it is important to bring
the probe to a short enough distance from the target, so as to avoid including other
points into the field of measurement.

4.4 MEASUREMENT PARAMETERS
The choice and setting of the measurement parameters is carried out by
successively pressing the MODE button:
■ EMI (see fig to right)
The emissivity percentage is adjusted using the
buttons qpaccording to the surface being
tested. (see table § 8.2).
Pressing the buttons qp briefly or holding
them down for a longer period gives smaller or
greater degrees of adjustment respectively. The
setting is held in memory after the instrument is
switched off and used during all successive
measurements, whatever the parameter used.
■ MAX (see fig to right)
When the trigger is pressed and held, the small
right-hand display indicates the maximum
temperature value measured whilst the trigger
is pressed.
The measurement set-up is held in memory
after the instrument is switched off, but not the
last maximum value recorded since the
instrument takes into account the value
measured upon the first press of the trigger
when switching on.

■ MIN (see fig to right)
When the trigger is pressed and held, the small
right-hand display indicates the minimum
temperature value measured whilst the trigger
is pressed.
The measurement set-up is held in memory
after the instrument is switched off, but not the
last minimum value recorded since the
instrument takes into account the value
measured upon the first press of the trigger
when switching on.
■ DIF (see fig to right)
When the trigger is pressed and held, the small
right-hand display indicates the temperature
difference measured as of the start of
measurement.
The measurement set-up is held in memory
after the instrument is switched off, but not the
last temperature difference value recorded
since the instrument takes into account the
value measured upon the first press of the
trigger when switching on.
■ AVG (see fig to right)
When the trigger is pressed and held, the small
right-hand display indicates the average
temperature value measured whilst the trigger
is pressed.
The measurement set-up is held in memory
after the instrument is switched off, but not the
last average value recorded since the
instrument takes into account the value
measured upon the first press of the trigger
when switching on.
