User Manual

Functional description and operating instructions

 Please take the time to read through this operating manual carefully to ensure that you are familiar with all the functions of your CMAC

4230.

Operation

All objects with a temperature above absolute zero radiate infrared energy that spreads in all directions at the speed of light. If an infrared thermometer is aimed at a measurement object, the lens gathers the energy and focuses it on an infrared sensor. The sensor reacts by generating a voltage signal that is directly proportional to the absorbed energy. The microprocessor-controlled electronic unit of the device can determine and display the current temperature using additional parameters.

Measurement objects with a shiny or polished surface not only radiate energy, but also reflect a part of the radiation from their surroundings.

An emissivity factor between 0.1 and 1.5 takes account of this fact so that only the actually radiated (and not the reflected) energy is included in the calculation of the measured value. The majority of applications are measured with an emissivity of

0.95. The CMAC 4230 is therefore preset to 0.95 and can be adjusted in steps of

0.01 depending on the application. Emissivity range over 1.00 is intended for applications, where adjacent measurement objects having different temperatures are to be measured. For example, this is the case if there are two conveying lines with different temperatures and the temperature of the colder one is to be measured.

The radiated reflected energy would thereby falsify the measurement and hence a correct result would be impossible. The temperature can now also be measured accurately using the emissivity setting > 1.00 by way of a one-time reference measurement using a contact thermometer.

Measuring marking

Keep in mind that the measured part of the object surface (3 point measuring spot marking) changes with the increasing measuring distance as shown in the figure.

19 mm @ 1150 mm

Focus point E:M = 60:1 Distant field E:M= 35:1

The ratio between the measuring distance and measuring spot diameter is approximately 60: 1 at distance (e) between the sensor and the measurement object

Wireless Infrared Thermometer CMAC 4230

Functional description and operating instructions

Measurement

(mm) the focus point and approximately 35:1 in the distant field (> 10 m). To take continuous readings, set the LOCK switch in the battery compartment to On and press the measurement button (the laser does not remain on continuously). Reset the LOCK switch to Off for the normal operation. The laser sight makes sighting a measurement object easier. Laser points indicate the exact diameter of the measuring spot. Use the LASER function key for switching the laser on and off by keeping the measurement button pressed. The laser icon (refer to 8.5 Display screen) indicates the switched-on laser.

Measurement

Aim at the object to be measured and press the measurement button. The measured temperature appears in the display. It is visible in the display for seven seconds after releasing the measurement button. If another button is not pressed, the device switches off automatically after this time. Selected functions remain set and the function selection menu returns to the initial position. To recall the last measured value, press ENTER without pressing the measurement button.

Emissivity

Asbestos

Asphalt

Basalt

Concrete

Most organic materials as well as lacquered and oxidized surfaces have an emissivity of 0.95. The emissivity is preset to 0.95 in the CMAC 4230 for this reason, but can be changed using the rocker switch. The determination of the temperatures of shiny or highly polished metal surfaces results in inaccurate measured values. To compensate for this, the surface to be measured can be covered with adhesive tape or painted matt black. Wait until the adhesive tape attains the same temperature as the material underneath it. Then determine the temperature of the adhesive tape

(corresponds to the material) or the painted surface.
