8. Product description

a) Function Infrared thermometers measure the surface temperature of an object. The sensor on the product records the heat radiationemitted,reectedandtransmittedthroughtheobject,andconvertsthisinformationintoatemperaturevalue. Emissivity is used to describe the energy emission characteristics of a material. The higher the emission level, the more radiation a material can emit. Many organic materials and surfaces have an emission level of approx. 0.95. Metallic surfaces or shiny materials have a lower emission level. This will cause an inaccurate reading. For this reason, a matt black layer of paint or matt adhesive tape should be applied to metallic shiny surfaces.35 b) IR measuring optics - ratio measuring distance:measuring surface (D:S = Distance:Spot) In order to obtain precise measuring results, the measured object must be larger than the IR measuring spot. The measured temperature is calculated using the average temperature of the measured area. The smaller the object, the closer it must be to the thermometer. The exact size of the measuring spot is shown in the following diagram. It is also indicated on the thermometer. To ensure precise measurements, the measured object should be at least twice the size of the IR measuring spot. The smallest measurement diameter is achieved up to a distance of 90 cm. The measurement diameter is 18 mm. However,keepsufcientdistancetoavoidfaultymeasurementduetoheatingoftheIRthermometer. Example: At a distance of 2 m, the measurement diameter is 40 mm. c) Target laser The target laser is active depending on the default setting during measurement. A warning symbol appears in the display if the laser is active (E). Never look into the laser outlet (8) during a reading. The target laser is constructed in dual design and marks the inner, approximate edge area of the measuring surface (approx.90%). When both laser spots meet, the smallest measuring surface has been achieved. This is 18 mm in diameter. With larger distances, the two laser spots move apart, analogue to the measuring surface.36

10. Taking measurements

In order to obtain exact measured values, the infrared thermometer has to be adjusted to the ambient temperature. Allow the device to adjust to the ambient temperature after relocation. Prolonged measurement of high temperatures at near measuring distances leads to self-heating of the measuring device and thus to inaccurate measurements. In order to obtain exact measured values, remember the following rule of thumb: The higher the temperature, the greater the measuring distance and the shorter the measuring time. Shiny surfaces affect the IR measurement results. To compensate, the shiny part of the surface can be covered with adhesive tape or matt black paint. The device cannot measure through transparent surfaces such as e.g. glass. Instead, it measures the surface temperature of the glass.39 a) IR measurement Point the laser outlet (9) at the object to be measured at a 90° angle. Make sure the object to be measured is not smaller than the IR measuring surface of the device. Press and hold the measuring button (5). The measured value (B) is shown in the display. The displayed value corresponds with the average surface temperature of the IR measuring surface. “SCAN” (D) appears on the display while the temperature is being measured. If the temperature measuring range is exceeded, "----" is displayed. After releasing the measuring button (5), the last measured value is displayed until the product powers off automatically. “Hold” (D) is also displayed. After releasing the measuring button (5), the device switches off automatically when the preset time elapses. To determine the warmest/coldest spot on the object to be measured, pass the laser outlet over the entire surface area of the object while holding the measuring button (5). Additional functions allow the automatic display of the maximum value and minimum value “Min” or “Max”, average value “Avg” and the difference value "Dif". These values are displayed above and below the main measurement display. The additional functions “Min” and “Dif” are not available when a contact sensor is connected. The display shows the sensor temperature “TK” here. b) Contact measurement Contact temperature measurement is permissible in combination with non-rotating and voltage-free stationary objects only. Contact temperatures are only possible up to the approved temperature of the sensor. The permitted temperature of the included wire sensor is -20 to +250 °C. In order to take advantage of the entire measuring range of the measuring device, an optional wire sensor with a higher maximum temperature is required. In addition to contactless IR measurement, a type-K thermocouple contact sensor may also be attached to the device. Contact measurement allows for measurement of temperature regardless of the object’s material and emission level. In addition to the included wire temperature sensor, all conventional K-type thermocouple sensors with miniature plug be connected to the device. Sensor connection Open the side cover (1) on the device. Plug the thermocouple plug of the sensor with correct polarity into the sensor socket. Pay attention to the “+”markingontheplugandthesocket.Theplugtsonlyinonedirectionintothesocket. As soon as a thermal sensor is connected with the measuring device, in measuring mode the display shows “TK” with the temperature of the sensor beneath the IR measuring value. After measuring, remove the sensor and close the cover to prevent dirt from entering the device. The additional functions “Min”, “Max”, “Avg” and “Dif” are not possible with contact measurement. These values pertain to IR measurements only.40 c) Additional functions The measuring device has various additional functions which can be used individually. Select and set these additional functions with “F1”, “F2” and “F3”. Press the “MODE” button to switch menu lines: The corresponding functions for the function buttons are displayed individually depending on the menu. The additional functions “MnMx”, “Save”, “Avg”, “Mem” “E”, “Hi” or “Lo” are not possible with contact measurement. These functions pertain to IR measurements only. Minimum, maximum, average and differential measurement function The “Min”, “Max”, “AVG” and “Dif” measured values are saved during measurement (display shows “SCAN”) regardless of the currently displayed measuring function and are retained until the measuring device switches off automatically. Set the automatic power-off time from 7 to 60 seconds for convenient reading of measurement values. During breaks in measurement, toggle between and read these values (display shows “HOLD”). During measurement, it is not possible to toggle between the “MnMx” and “Avg” function. You can select a display either before or after measurement. Turnthemeasuringdeviceonbybrieypressingthemeasuringbutton(5). Select the desired display “MnMx/Avg” with “F1” or “F3” and conduct the measurement. After measuring, release the measuring button. Within the preset power-off time, enter the “MnMx/Save/Avg” setting mode with the “MODE” button. Press “F1” to display the minimum and maximum values. Press “F3” to display the average and difference values. The average value “Avg” is calculated from the last measurement period. The difference value “Dif” shows the difference between the minimum and maximum values. Saving measured values "Save" The “Save” function allows you to save up to 30 IR measure values in the internal memory. The stored data can be read on the device via the “Mem” function or transferred to a computer via USB. The storage of the measured data is only possible during breaks in measurement (display shows “HOLD”), before the measuring device switches off automatically. Set the automatic power-off time from 7 to 60 seconds for convenient storage of measurement values. Turnthemeasuringdeviceonbybrieypressingthemeasuringbutton(5)andconductthemeasurement.
