Infrared Thermal Radiation

Infrared thermal radiation is electromagnet. ic radiation emitted by every body above 0 Kelvin (-459°F, -273°C). The amount of ra- diation depends on the temperature and the emissivity of the body.

The emissivity degree of an object depends on the material and the structure of its surface. lt states how much infrared heat radiation the object emits compared to an ideal heat emitter (black body, emissivity degree = 1).

À thermal bridge is an object that undesir- ably transmits heat outwards or inwards, therefore differing significantly from the temperature of the rest of a wall or from the desired temperature of a wall.

As the surface temperature at thermal bridg- es is Lower than in the rest of the room, the risk of mold 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 mate- rial, 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 mea- sured 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.

The tool can be operated using a Bosch Li- ion rechargeable battery.

Operation with Battery Pack (Fig. 3)

Use only Bosch recharge- PUTAIN apte tthiumeion battery packs listed in the speci ns section of this manual. Use of other battery packs may

increase the risk of fire, personal injury and property damage.

Remove the batteries PLATE) som the too when not using it for extended periods. When storing

for extended periods, the batteries can cor- rode and self-discharge.

Note: The battery pack is supplied partially charged. To ensure full capacity of the bat- tery pack, completely charge the battery pack in the battery charger before using for the first time.

Use only Bosch chargers PLUIE) listed in the specifica- tions section of this manual. Use of other

chargers may increase the risk of fire, per- sonal injury and property damage.

The lithium-ion battery pack can be charged at any time without reducing its service life. Interrupting the charging procedure does not damage the battery pack.

The lithium-ion battery is protected against deep discharge by the Electronic Cell Protec- tion (ECP). À protective circuit switches the laser Level off when the battery is drained.

+ Following the automatic shut off of the tool, do not continue to press the On/ Off button. The battery can be dam- aged.

Battery Status Indicator (Fig. 1)

The Battery Charge Indicator 34 on the dis- play shows the state of charge of the Battery Pack 22.

TN Inserting/Changing the Coin Cell (Fig. 4, Fig. 5)

If the coin cell holder PLEUATME cannot be closed cor- rectly and fully, stop using the measuring

tool, remove the coin cell and have the measuring tool repaired.

To be able to save the time on the detection tool, a Coin Cell 44 must be used.

Unscrew the Screw 45 on the Coin Cell Holder 46. Pull the Coin Cell Holder 46 out of the Coin Cell Port 47 with an auxiliary tool (e.g. a flat-head screwdriver).

Remove the discharged Coin Cell 44 and in- sert a new Coin Cell 44 (CR2032). Ensure that the polarity is correct according to the illustration on the coin cell holder (the posi- tive terminal of the coin cell must be facing upwards).

With the Coin Cell 44 fitted, slide the Coin Cell Holder 46 into the Coin Cell Port 47. Ensure that the Coin Cell Holder 46 is in- serted correctly and fully, as otherwise pro- tection from dust and splashes is no longer guaranteed.

+ Protect the measuring tool against moisture and direct sun Light.

Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not Leave it in vehicles for a Long time. In case of large variations 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 tool is correctly acclimatized. In the event of severe tem- perature fluctuations or environmental conditions which vary to a large degree, the measurement accuracy of the mea- suring tool may be impaired until it is fully acclimatized again.

Avoid hard knocks to the tool or drop- ping it. After severe external influences and in the event of abnormalities in the functionality, you should have the mea- suring tool checked by an authorized Bosch after-sales service agent.

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 tool, press the On/Off But- ton 12. A start sequence will appear in the Display 18. After the start sequence, the measuring tool will immediately begin to measure and will measure continuously until it is switched off.

Note: In the first few minutes, the measur- ing tool may self-calibrate several times, as the sensor temperature and ambient tem- perature have not yet been brought into line. Performing calibration again enables precise measurement. The thermal image freezes briefly during calibration.

During this time, the temperature indicator may show . The thermal image will freeze briefly during sensor calibration. If the ambi- ent temperature fluctuates significantly, this effect is increased. If possible, you should therefore turn on the measuring tool a few minutes before starting to measure, so that the tool can stabilise thermally.

To switch off the tool, press the On/Off But- ton 12 again. The measuring tool saves all settings and then switches itself off. Close the Protective Cap 1 to transport the mea- suring tool safely.

In the “Settings” menu, you can choose whether and after how much time the mea- suring tool automatically switches off. (See "<Shutdown Time>" under “<Tool>” on page 19.)

lf the battery or the measuring tool is not within the operating temperature range stat- ed in the specifications, the measuring tool will shut down automatically after à brief warning. (See “Troubleshooting” on 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 sur- face. This specifies how much infrared ther- mal radiation the object emits compared with an ideal radiant warmer (black body, emissivity € = 1) and accordingly has a value between 0 and 1.

To determine the surface temperature, the tool performs a contactless measurement of the natural infrared thermal radiation emit- ted by the object at which the tool is aimed. To ensure correct measurement, the emis- sivity setting on the measuring tool must be checked before every measurement and adapted to the measuring object if neces- sary.

You can select one of the preset emissiv- ity Levels or enter an exact numerical value. Adjust the required emissivity using the “Measurement” -> “Emissivity” menu. (See "<Emissivity>" under "<Measurement>" on page 18.)

The Lower the emissivity, the greater the ef- fect of the reflected temperature on the mea- suring result. Always adjust the reflected temperature when changing the emissivity. Set the reflected temperature via the <Mea-

surement> -> <Reflected Temp.> menu. (See "Main Menu", page 18.)

Temperature differences allegedly shown by the measuring tool may be caused by differ- ent temperatures and/or different emissivity levels. If the emissivity levels are very dif- ferent, the depicted temperature differences may differ considerably from the actual tem- perature differences.

À WARNING Temperature measure-

ments will only be cor- rect if the emissivity setting and the emis- sivity of the object match.

Differences in color may be caused by differ- ent temperatures and/or different emissivity levels. If the emissivity levels are very dif- ferent, the depicted temperature differences may differ considerably from the actual tem- perature differences.

If there are multiple objects made of dif- ferent materials or that have different structures in the measurement range, the displayed temperature values are only con- clusive for the objects that match the emis- sivity setting.

For all other objects (with different emissiv- ity levels), the displayed color differences can be used as an indication of temperature relationships.

Notes on the Measuring Conditions

Highly reflective or shiny surfaces (e.g. shiny tiles or polished metals) may distort or im- pair the results shown. If necessary, mask the surface to be measured with à dark, matt adhesive tape that conducts heat well. Allow the tape to acclimatize briefly on the surface.

Make sure that a favorable measuring angle is used on reflective surfaces in order to ensure that the thermal radiation reflected by other objects does not distort the result. For example, the reflection of your own body heat may interfere with the measure- ment when measuring head-on from a per- pendicular 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 (emit- ted value or real value of the surface). Mea- suring through transparent materials (e.g. glass or transparent plastics) is fundamen- tally not possible.

The accuracy and reliability of the measuring results increase with better and more stable measuring conditions.

Infrared temperature measurement is im- paired by smoke, vapor/high air humidity or dusty air.

Information for achieving improved measure- ment accuracy:

+ Get as close as possible to the measur- ing object to minimize interfering factors between you and the surface to be measured.

Ventilate indoor areas prior to mea- surement, especially when the air is contaminated or extremely steamy. After ventilating, allow the room to acclima- tie for a while until the usual tempera- ture has been reached again.

Assigning Temperatures on the Basis of the Scale

A Color Scale 36 is shown on the right-hand side of the display. The values at the top and bottom end are oriented to the Maximum Temperature 35 and Minimum Temperature 37 recorded in the thermal image. For the scale, 99.9% of the total pixels are evaluat- ed. Colors are assigned to temperature val- ues with a uniform distribution in the image (linearly).

Different shades can therefore be used to assign temperatures within these two Limit values. For example, à temperature that is exactly between the maximum and minimum value is assigned to the centre color range of the scale.

To determine the tempera- ture of a specific area, move the measuring tool so that the Crosshairs with Temperature | À Indicator 40 are aimed at the required point or area. In the automatic setting, the color spectrum of the scale is always distributed linearly (= uniform- y) across the entire measuring range between the maximum and minimum temperatures.

The measuring tool displays all measured temperatures in the measuring range in relation to one another. If heat is displayed as blue in the color palette in an area, for example in à color representation, this means that the blue ar- eas are among the colder measured values in the current measuring range. However, these areas may still be in a temperature range which could cause injuries in certain circumstances. You should therefore always note the temperatures displayed on the scale or at the crosshairs themselves.

Depending on the measurement conditions, different color palettes can make it easier to analyze the thermal image and show objects or circumstances more clearly in the display. This does not affect the measured tempera- tures. Only the way in which the tempera- ture values are shown changes.

+ Transparency - The thermal image displayed is placed on top of the real image in such a way that it is slightly transparent. This enables improved detection of objects.

You can adjust the setting by pressing the Up Arrow Button 8 or Down Arrow Button 13.

Fixing the Scale (Fig. 1)

The color distribution in the thermal image is adjusted automatically but can be fixed by pressing the Right-Hand Function Button 10. This enables a comparison to be made be- tween thermal images taken under different temperature conditions (e.g. when checking several rooms for thermal bridges). It also allows an extremely cold or hot object to be hidden in the thermal image. This object would otherwise distort the image (e.g. à radiator as a hot object when searching for thermal bridges).

To switch the scale back to automatic, press the Right-Hand Function Button 10 again. The temperatures are now dynamic again and adapt to the measured minimum and maximum values.

Superimposition of Thermal Image and Real Image

For improved orientation (= local assign- ment 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 image is accurate at a distance of 22 in (0.55 m). If the tool is closer to or further away from the object being mea- sured, this may result 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.

Picture in picture - 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.

To call up further functions that may be helpful for the display, press the Measuring Functions Button 9 button. Use the Left- Hand Arrow Button 15 or the Right-Hand Arrow Button 11 to navigate through the dis- played options to select a function. Select a function and press the Measuring Functions Button 9 button again.

The following measuring functions are avail- able:

+ <Automatic> — Colors are distributed automatically in the thermal image.

Note: To ensure high accuracy across the entire measuring range, measure- ments are carried out in two tem- perature ranges. With the <Automatic> measuring function, the measuring tool automatically selects the appropriate temperature range according to the temperature distribution in the thermal image. When doing so, it assesses how

many measured values fall above a cer- tain temperature threshold. If very small but hot objects are being measured, it may select the Low temperature range that is not suitable for high tempera- tures. This can be determined from the preceding symbol, -. In such cases, switch to the <Manual> measuring func- tion, in which the color distribution cor- responds to the set temperature range.

<Heat Detector> - Only the warmer temperatures in the measuring range are displayed as a thermal image in this measuring function. The area outside these warmer temperatures is shown as a real image in grey scale. The depiction in grey scale prevents colored objects from being wrongly associated with tem- peratures (e.g. a red cable in the control cabinet when searching for overheated components). Adjust the scale using

the Up Arrow Button 8 and Down Arrow Button 13. This expands or reduces

the temperature range, thereby expand- ing or reducing the thermal image. The measuring tool continues to measure minimum and maximum temperatures and displays these at the ends of the Color Scale 36.

<Cold Detector> — Only the colder temperatures in the measuring range are displayed as a thermal image in this measuring function. The area outside these colder temperatures is shown as a real image in grey scale to prevent colored objects from being wrongly associated with temperatures (e.g. a blue window frame when searching for faulty insulation). Adjust the scale using the Up Arrow Button 8 and Down Arrow Button 13. This expands or reduces

the temperature range, thereby expand- ing or reducing the thermal image. The measuring tool continues to measure minimum and maximum temperatures and displays these at the ends of the Color Scale 36.

<Manual> — If greatly deviating tempera- tures are measured in the thermal image (eg. a radiator as a hot object when searching for thermal bridges), the available colors 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 differences can no longer be shown in detail. To obtain à detailed depiction of the temperature range to be examined, take the following steps: After switching to <Manual> mode, you can set the maximum and the minimum temperature. Doing this enables you to set the temperature range that is rele- vant to you and in which you would Like to detect subtle differences. The <Reset scale> setting automatically readjusts the scale to the measured values in the infrared sensor's field of view.

<Emissivity> 32 — A selection of saved emissivities is available for some of the most common materials. Choose the relevant material in the <Material> menu item. The corresponding emissivity is shown in the line beneath. If you know the exact emissivity of the object you want to measure, you can also set it as à numerical value in the <Emissivity> menu item.

If you frequently measure the same materials, you can enter five emissivities as favorites and quickly call them up via the bar at the top (numbered from 1 to 5).

<Reflected Temp.> 31 - Setting this pa- rameter can improve the accuracy of the measuring result, especially with Low- emissivity (= high-reflection) materials. In some situations (especially in indoor areas) the reflected temperature cor- responds to the ambient temperature. If there are objects with greatly deviating temperatures close to highly reflective objects, this value should be adjusted as the measurement may be affected.

+ <Centerspot> 40 - The point is dis- played in the centre of the thermal image and shows you the measured temperature value at this point.

<Hotspot> 39: <ON>/<OFF> - The hottest point (= measuring pixel) is in- dicated by red crosshairs in the thermal image. This facilitates the search for critical areas (e.g. a Loose contact termi- nal in the control cabinet). To make the measurement as accurate as possible, focus the object to be measured in the centre of the display (186 * 140 px). This way, the corresponding tempera- ture value of this object will be shown as well.

<Coldspot> 41:<ON>/<OFF> — The cold- est point (= measuring pixel) is indi- cated by blue crosshairs in the thermal image. This facilitates the search for critical areas (e.g. a Leak in a window). To make the measurement as accurate as possible, focus the object to be mea sured in the centre of the display (186

<Color Scale> 36: <ON>/<OFF>

<Average Temp.> 30: <ON> / <OFF> The average temperature 30 is displayed at the top Left of the thermal image (average temperature of all measured values in the thermal image). This can help you to determine the reflected temperature.

+ <Language> - Under this menu item, you can select the language used in the display.

<Time & Date> 29 - To change the time and date shown in the measuring tool, call up the <Time & Date> submenu. This submenu not only allows you to set the time and date but also to change their respective formats.

Infrared thermal radiation

Infrared thermal radiation is electromag- netic radiation emitted by every body above 0 Kelvin (-273°C). The amount of radiation depends on the temperature and the emis- sivity of the body.

The emissivity of an object depends on the material and the structure of its surface. This specifies how much infrared thermal radia- tion the object emits compared with an ideal radiant warmer (black body, emissivity & 1) and accordingly has a value between O and 1.

A thermal bridge is defined as a position on the external wall of a building, where there is a Localized increase in heat loss due to a structural defect.

Thermal bridges can lead to an increased risk of mold.

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 mate- rial, background radiation is reflected in the object to be measured, therefore distorting the actual temperature result.
