Operation with Battery Adapter (Removable) (see figure A) The batteries are inserted into the battery adapter. The non-rechargeable battery adapter is intended only for use in designated Bosch measuring tools and must not be used with power tools. To insert the batteries, slide the cover of the battery adapter 21 into the battery port 18. Place the batteries in the cover as per the illustration on the sealing cap 20. Slide the sealing cap over the cover until you feel it click into place and it is flush with the handle of the measuring tool. To remove the batteries, press the release buttons 19 of the sealing cap 20 and pull off the sealing cap. In doing so, make sure that the batteries do not fall out. To do this, hold the measuring tool with the battery port 18 facing upwards. Remove the batteries. To remove the inside cover 21 from the battery port 18, reach into the cover recess 22 and pull it out of the measuring tool by applying light pressure to the side wall (see figure B). Note: Do not use any tools (e.g. a screwdriver) to remove the battery, as this could break the casing. Always replace all batteries at the same time. Only use batter- ies from one brand and with the identical capacity. Remove the batteries from the measuring tool when not using it for extended periods. When storing for ex- tended periods, the batteries can corrode and self-dis- charge. Operation with Battery Pack (see figure C) Note: Use of battery packs not suitable for the measuring tool can lead to malfunctions of or cause damage to the measuring tool. Note: The battery pack is supplied partially charged. To en- sure full capacity of the battery pack, completely charge the battery pack in the battery charger before using for the first time. Use only the chargers listed in the technical data. Only these battery chargers are matched to the lithium-ion bat- tery of your measuring tool. The lithium-ion battery pack can be charged at any time with- out reducing its service life. Interrupting the charging proce- dure does not damage the battery pack. Following the automatic shut off of the measuring tool, do not continue to press the On/Off button. The battery can be damaged. To insert the charged battery pack 23, slide it into the battery port 18 until you feel it engage and it is flush with the handle of the measuring tool. To remove the battery pack 23, press the unlocking buttons 19 and pull the battery pack out of the battery port 18. Do not use force to do this. Battery Status Indicator The battery status indicator f on the display shows the charg- ing state of the batteries or battery pack 23. Operation Protect the measuring tool against moisture and direct sun light. Do not subject the measuring tool to extreme tempera- tures or variations in temperature. As an example, do not leave it in vehicles for a long time. In case of large vari- ations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in tempera- ture, the accuracy of the measuring tool can be impaired. Make sure that the measuring tool is correctly acclima- tised. In the event of severe temperature fluctuations or environmental conditions which vary to a large degree, the measurement accuracy of the measuring tool may be im- paired until it is fully acclimatised again. Avoid hard knocks to the measuring tool or dropping it. After severe external influences and in the event of abnor- malities in the functionality, you should have the measur- ing tool checked by an authorised Bosch after-sales ser- vice agent. Initial Operation Switching On and Off To take a measurement, fold the protective cap 1 upwards. Make sure that the infrared measuring area is not closed off or covered while working. To switch on the measuring tool, press the On/Off button 9. A start sequence will appear in the display 14. After the start sequence, the measuring tool will immediately begin to meas- ure and will measure continuously until it is switched off. Note: In the first few minutes, the measuring tool may self- calibrate several times, as the sensor temperature and ambi- ent temperature have not yet been brought into line. Perform- ing calibration again enables precise measurement. The ther- mal image freezes briefly during calibration. To switch off the measuring tool, press the On/Off button again. The measuring tool saves all settings and then switches itself off. Close the protective cap 1 to transport the measur- ing tool safely.

If the battery or the measuring tool is not within the operating temperature range stated in the Technical Data, the measur- ing tool will shut down automatically after a brief warning (see “Troubleshooting – Causes and Corrective Measures”, page 23). Allow the measuring tool to reach to the correct temperature and then switch it back on. To save energy, only switch the measuring tool on when you are using it. Preparing for Measurement Setting the Emissivity Degree for Surface-temperature Measurements The emissivity degree of an object depends on the material and the structure of its surface. It indicates whether an object (in comparison with other objects with the same tempera- ture) emits much or little infrared heat radiation. To determine the surface temperature, the tool performs a contactless measurement of the natural infrared thermal radi- ation emitted by the object at which the tool is aimed. To en- sure correct measurement, the emissivity setting on the measuring tool must be checked before every measure- ment and adapted to the measuring object if necessary. You can select one of the preset emissivity levels or enter an exact numerical value. Adjust the required emissivity using the “Measurement” >“Emissivity” menu (see page 21). Temperature measurements will only be correct if the emissivity setting and the emissivity of the object match. Differences in colour may be caused by different tempera- tures and/or different emissivity levels. If the emissivity levels are very different, the depicted temperature differences may differ considerably from the actual temperature differences. If there are multiple objects made of different materials or that have different structures in the measurement range, the displayed temperature values are only conclusive for the ob- jects that match the emissivity setting. For all other objects (with different emissivity levels), the displayed colour differ- ences can be used as an indication of temperature relation- ships. Notes on the Measuring Conditions Highly reflective or shiny surfaces (e.g. shiny tiles or polished metals) may distort or impair the results shown. If necessary, mask the surface to be measured with a dark, matt adhesive tape that conducts heat well. Allow the tape to acclimatise briefly on the surface. Make sure that a favourable measuring angle is used on reflec- tive surfaces in order to ensure that the thermal radiation re- flected by other objects does not distort the result. For exam- ple, the reflection of your own body heat may interfere with the measurement when measuring head-on from a perpendicular position. On a level surface, the outline and temperature of your body could therefore be displayed (reflected value), and these values do not correspond to the actual temperature of the measured surface (emitted value or real value of the surface). Measuring through transparent materials (e.g. glass or trans- parent plastics) is fundamentally not possible. The accuracy and reliability of the measuring results increase with better and more stable measuring conditions. Infrared temperature measurement is impaired by smoke, va- pour/high air humidity or dusty air. Information for achieving improved measurement accuracy: – Get as close as possible to the measuring object to mini- mise interfering factors between you and the surface to be measured. – Ventilate indoor areas prior to measurement, especially when the air is contaminated or extremely steamy. After ventilating, allow the room to acclimatize for a while until the usual temperature has been reached again. Assigning temperatures on the basis of the scale A scale is shown on the right-hand side of the dis- play. The values at the top and bottom end are ori- ented to the maximum and minimum temperature recorded in the thermal image. Colours are as- signed to temperature values with a uniform distri- bution in the image (linearly). Different shades can therefore be used to assign temperatures within these two limit values. For ex- ample, a temperature that is exactly between the maximum and minimum value can be assigned to the centre colour range of the scale. To determine the temperature of a specific area, move the measuring tool so that the crosshairs with temperature display l are aimed at the re- quired point or area. In the automatic setting, the colour spectrum of the scale is always distributed linearly (= uniformly) across the entire measurement range between the maximum and minimum temperatures. The thermal imaging camera displays all measured tempera- tures in the measurement range in relation to one another. If heat is displayed as blue in the colour palette in an area, for example in a colour representation, this means that the blue areas are among the colder measured values in the current measurement range. However, these areas may be in a tem- perature range that could cause injuries in certain circum- stances. You should therefore always note the temperatures displayed on the scale or at the crosshairs themselves.

This does not affect the measured temperatures. Only the way in which the temperature values are shown changes. To change the colour palette, remain in measuring mode and press the right-hand 8 or left-hand 12 arrow button. Superimposition of thermal image and real image For improved orientation (= local assignment of the thermal image displayed), with matched temperature ranges, a visual real image can additionally be inserted. Note: The superimposition of the real image and thermal im- age is accurate at a distance of 0.55 m. If the tool is closer to or further away from the object being measured, this may re- sult in misalignment of the real image and thermal image. The thermal imaging camera offers you the following options: – Complete infrared image Only the thermal image is displayed. – Image in image The thermal image displayed is cropped and the surround- ing area is shown as a real image. This setting improves the local assignment of the measurement range. – Transparency The thermal image displayed is placed on top of the real im- age in such a way that it is slightly transparent. This ena- bles improved detection of objects. You can adjust the setting by pressing the up 5 or down 10 arrow buttons. Fixing the scale The colour distribution in the thermal image is adjusted auto- matically but can be fixed by pressing the right-hand function button 7. This enables a comparison to be made between thermal images taken under different temperature conditions (e.g. when checking several rooms for thermal bridges). To switch the scale back to automatic, press the right-hand function button 7 again. The temperatures are now dynamic again and adapt to the measured minimum and maximum values. Measuring functions To call up further functions which may be helpful for the dis- play, press the “Func” button 6. Use the right-hand/left-hand buttons to navigate through the displayed options to select a function. Select a function and press the “Func” button 6 again. The following measuring functions are available: – “Automatic” Colours are distributed automatically in the thermal image – “Heat detector” Only the warmer temperatures in the measurement range are displayed as a thermal image in this measuring func- tion. The area outside these warmer temperatures is dis- played in greyscale as a real image so that coloured objects are not wrongly associated with temperatures (e.g. red ca- ble in the control cabinet when looking for overheated components). Adjust the scale using the up 5 and down 10 buttons. This expands or reduces the temperature range shown. The tool continues to measure minimum and maximum temperatures and displays these at the ends of the scale. You can, however, control which temperature range is shown in colour as a thermal image. – “Cold detector” Only the colder temperatures in the measurement range are displayed as a thermal image in this measuring func- tion. The area outside these colder temperatures is dis- played in greyscale as a real image so that coloured objects are not wrongly associated with temperatures (e.g. blue window frame when looking for faulty insulation). Adjust the scale using the up 5 and down 10 buttons. This ex- pands or reduces the temperature range shown. The tool continues to measure minimum and maximum temperatures and displays these at the ends of the scale. You can, however, control which temperature range is shown in colour as a thermal image. – “Manual” If greatly deviating temperatures are measured in the ther- mal image (e.g. radiator as a hot object when searching for thermal bridges), the available colours are distributed among a large number of temperature values in the range between the maximum and the minimum temperature. This can result in a situation where subtle temperature differenc- es can no longer be shown in detail. To obtain a detailed de- piction of the focus temperature, switch to “Manual” mode and set the maximum and the minimum temperature. Doing this enables you to set the temperature range that is relevant to you and in which you would like to detect subtle differenc- es. The Reset setting automatically readjusts the scale to the measured values in the infrared sensor’s field of view. Main Menu To access the main menu, press the “Func” button 6 to call up the measuring functions. Now press the right-hand function button 7. – “Measurement” – “Emissivity” c: A selection of saved emissivity levels is available for some of the most common materials. Select the appro- priate material in the “Material” menu item. The corre- sponding emissivity is displayed in the line below. If you know the exact emissivity of the object to be meas- ured, you can also set it as a numerical value in the “Emissivity” menu item. – “Reflected temperature”: Setting this parameter improves the accuracy of meas- uring results, especially with low-emissivity (= high-re- flection) materials. The reflected temperature normally corresponds to the ambient temperature. If there are objects with greatly deviating temperatures close to highly reflective objects which could affect the measurement, this value should be adjusted.

OBJ_BUCH-3136-002.book Page 23 Tuesday, August 22, 2017 6:26 PM24 | English 1 609 92A 3RD | (22.8.17) Bosch Power Tools Definitions Infrared heat radiation Infrared heat radiation is electromagnetic radiation emitted by every body. The amount of radiation depends on the tem- perature and the emissivity degree of the body. Emissivity Degree The emissivity degree of an object depends on the material and the structure of its surface. It states how much infrared heat radiation the object emits compared to an ideal heat emitter (black body, emissivity degree = 1). Thermal Bridge A thermal bridge is an object that undesirably transmits heat outwards or inwards, therefore differing significantly from the temperature of the rest of a wall or from the desired tempera- ture of a wall. As the surface temperature at thermal bridges is lower than in the rest of the room, the risk of mould increases significantly at these locations. Reflected temperature/reflectivity of an object The reflected temperature is the thermal radiation that is not emitted by the object itself. Depending on the structure and material, background radiation is reflected in the object to be measured, therefore distorting the actual temperature result. Distance from the object The distance between the object being measured and the measuring tool influences the captured area size per pixel. You can capture increasingly large objects as the distance from the object becomes greater. TrackMyTools The built-in Bluetooth® Low Energy Module enables you to personalise and check the status of your measuring tool, as well as transfer settings and data using Bluetooth® wireless technology. TrackMyTools Bluetooth® module power supply The measuring tool is fitted with a button cell so that it can still be detected by a mobile device using TrackMyTools without having a battery pack 23 or batteries inserted. You can find further information directly in the app from Bosch. Data Transmission You can switch the TrackMyTools Bluetooth® module on and off in the tool settings. It then emits a continuous signal. The transmission interval of the module is eight seconds. Depending on ambient conditions, up to three transmission intervals may be required before the measuring tool is de- tected. Note: Switch TrackMyTools off in areas where the transmis- sion of radio waves is prohibited, for example on aeroplanes. Registering and setting up the app/web-based application Before you can use TrackMyTools, you need to register online. To do this, open the website www.bosch-trackmytools.com and register. After registration is complete, you will receive your access information.
