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).

C.A 1864

D/S : 30/1 Distance (D) / Spot diameter (S) Laser beam 16mm 10 à 300mm 30 à 900mm 50 à 1500mm Sensor beam S D

C.A 1866

D/S : 50/1 Distance (D) / Spot diameter (S) Laser beam 16mm 6.0 à 300mm 18 à 900mm 30 à 1500mm Sensor beam D S

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.

YES NO

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 q p according to the surface being tested. (see table § 8.2).

Pressing the buttons q p 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.

HOLD = 0.9

HOLD = 0.9

MAX 300

■ 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.

(1) C/F

Select the temperature units (°C or °F) using the °C/°F switch

(2) LOCK ON / OFF

To lock the unit on for continuous measurement, slide the middle switch LOCK ON/OFF right. If the trigger is pulled while the unit is lock on, the laser and backlight will turn on if they have been activated. When the unit is locked on, the backlight and laser will remain on unless it is turned off using the Laser/Backlight button on the keypad.

(3) SET ALARM

To activate the alarms, please slide the bottom switch SET ALARM right.

To set values for the High Alarm (HAL), Low Alarm (LAL), firstly active the display by pulling the trigger or press MODE, then press MODE until the appropriate code appears in the lower left corner of the display, press the UP and down buttons to adjust the desired values.
