WARNING
Applicability: Class B digital devices.
This equipment has been tested and found to comply with the limits for a Class B digital device, pur­suant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television recep­tion, which can be determined by turning the equipment off and on, the user is encouraged to try to cor­rect the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Safety information
WARNING
Only use the correct equipment to remove the electrical power from the battery. If you do not use the correct equipment, you can decrease the performance or the life cycle of the battery. If you do not use the correct equipment, an incorrect flow of current to the battery can occur. This can cause the battery to become hot, or cause an explosion. Injury to persons can occur.
WARNING
Make sure that you read all applicable MSDS (Material Safety Data Sheets) and warning labels on con­tainers before you use a liquid. The liquids can be dangerous. Injury to persons can occur.
CAUTION
Do not point the infrared camera (with or without the lens cover) at strong energy sources, for example, devices that cause laser radiation, or the sun. This can have an unwanted effect on the accuracy of the camera. It can also cause damage to the detector in the camera.
CAUTION
Do not use the camera in temperatures more than +50°C (+122°F), unless other information is specified in the user documentation or technical data. High temperatures can cause damage to the camera.
CAUTION
Do not attach the batteries directly to a car’s cigarette lighter socket, unless FLIR Systems supplies a specific adapter to connect the batteries to a cigarette lighter socket. Damage to the batteries can occur.
CAUTION
Do not connect the positive terminal and the negative terminal of the battery to each other with a metal object (such as wire). Damage to the batteries can occur.
CAUTION
Do not get water or salt water on the battery, or permit the battery to become wet. Damage to the bat­teries can occur.
CAUTION
Do not make holes in the battery with objects. Damage to the battery can occur.
CAUTION
Do not hit or cause shocks to the battery. Damage to the battery can occur.
CAUTION
Do not put the batteries in or near a fire, or into direct sunlight. When the battery becomes hot, the built­in safety equipment becomes energized and can stop the battery charging procedure. If the battery be­comes hot, damage can occur to the safety equipment and this can cause more heat, damage or igni­tion of the battery.
CAUTION
Do not put the battery on or near fires, stoves, or other high-temperature locations. Damage to the bat­tery and injury to persons can occur.
CAUTION
Do not solder directly onto the battery. Damage to the battery can occur.

Safety information
CAUTION
Do not use the battery if, when you use, charge, or put the battery in storage, there is an unusual smell from the battery, the battery feels hot, changes color, changes shape, or is in an unusual condition. Speak with your sales office if one or more of these problems occurs. Damage to the battery and injury to persons can occur.
CAUTION
Only use a specified battery charger when you charge the battery. Damage to the battery can occur if you do not do this.
CAUTION
Only use a specified battery for the camera. Damage to the camera and the battery can occur if you do not do this.
CAUTION
The temperature range through which you can charge the battery is ±0°C to +45°C (+32°F to +113°F), except for the Korean market where the approved range is +10°C to + 45°C (+50°F to +113°F). If you charge the battery at temperatures out of this range, it can cause the battery to become hot or to break. It can also decrease the performance or the life cycle of the battery.
CAUTION
The temperature range through which you can remove the electrical power from the battery is -15°C to +50°C (+5°F to +122°F), unless other information is specified in the user documentation or technical data. If you operate the battery out of this temperature range, it can decrease the performance or the life cycle of the battery.
CAUTION
When the battery is worn, apply insulation to the terminals with adhesive tape or equivalent materials before you discard it. Damage to the battery and injury to persons can occur if you do not do this.
CAUTION
Remove any water or moisture on the battery before you install it. Damage to the battery can occur if you do not do this.
CAUTION
Do not apply solvents or equivalent liquids to the camera, the cables, or other items. Damage to the bat­tery and injury to persons can occur.
CAUTION
Be careful when you clean the infrared lens. The lens has an anti-reflective coating which is easily dam­aged. Damage to the infrared lens can occur.
CAUTION
Do not use too much force to clean the infrared lens. This can cause damage to the anti-reflective coating.
Note The encapsulation rating is only applicable when all the openings on the camera are sealed with their correct covers, hatches, or caps. This includes the compartments for data storage, batteries, and connectors.

3.1 Calibration

We recommend that you send in the camera for calibration once a year. Contact your lo­cal sales office for instructions on where to send the camera.

3.2 Accuracy

For very accurate results, we recommend that you wait 5 minutes after you have started the camera before measuring a temperature.

3.3 Disposal of electronic waste

Electrical and electronic equipment (EEE) contains materials, components and substan­ces that may be hazardous and present a risk to human health and the environment when waste electrical and electronic equipment (WEEE) is not handled correctly.
Equipment marked with the below crossed-out wheeled bin is electrical and electronic equipment. The crossed-out wheeled bin symbol indicates that waste electrical and elec­tronic equipment should not be discarded together with unseparated household waste, but must be collected separately.
For this purpose all local authorities have established collection schemes under which residents can dispose waste electrical and electronic equipment at a recycling centre or other collection points, or WEEE will be collected directly from households. More de­tailed information is available from the technical administration of the relevant local authority.

7.18 Changing the emissivity as a custom value

7.18.1 General

For very precise measurements, you may need to set the emissivity, instead of selecting a surface property or a custom material. You also need to understand how emissivity and reflectivity affect measurements, rather than just simply selecting a surface property.
Emissivity is a property that indicates how much radiation originates from an object as opposed to being reflected by it. A lower value indicates that a larger proportion is being reflected, while a high value indicates that a lower proportion is being reflected.
Polished stainless steel, for example, has an emissivity of 0.14, while a structured PVC floor typically has an emissivity of 0.93.
For more information about emissivity, see section 12 Thermographic measurement techniques, page 35.

11.1 Moisture & water damage

11.1.1 General

It is often possible to detect moisture and water damage in a house by using an infrared camera. This is partly because the damaged area has a different heat conduction prop­erty and partly because it has a different thermal capacity to store heat than the sur­rounding material.
Many factors can come into play as to how moisture or water damage will appear in an infrared image.
For example, heating and cooling of these parts takes place at different rates depending on the material and the time of day. For this reason, it is important that other methods are used as well to check for moisture or water damage.

11.1.2 Figure

The image below shows extensive water damage on an external wall where the water has penetrated the outer facing because of an incorrectly installed window ledge.

11.2 Faulty contact in socket

11.2.1 General

Depending on the type of connection a socket has, an improperly connected wire can re­sult in local temperature increase. This temperature increase is caused by the reduced contact area between the connection point of the incoming wire and the socket , and can result in an electrical fire.
A socket’s construction may differ dramatically from one manufacturer to another. For this reason, different faults in a socket can lead to the same typical appearance in an in­frared image.
Local temperature increase can also result from improper contact between wire and socket, or from difference in load.

11.2.2 Figure

The image below shows a connection of a cable to a socket where improper contact in the connection has resulted in local temperature increase.

Application examples11

11.3 Oxidized socket

11.3.1 General

Depending on the type of socket and the environment in which the socket is installed, ox­ides may occur on the socket's contact surfaces. These oxides can lead to locally in­creased resistance when the socket is loaded, which can be seen in an infrared image as local temperature increase.
A socket’s construction may differ dramatically from one manufacturer to another. For this reason, different faults in a socket can lead to the same typical appearance in an in­frared image.
Local temperature increase can also result from improper contact between a wire and socket, or from difference in load.

11.3.2 Figure

The image below shows a series of fuses where one fuse has a raised temperature on the contact surfaces against the fuse holder. Because of the fuse holder’s blank metal, the temperature increase is not visible there, while it is visible on the fuse’s ceramic material.

11.4 Insulation deficiencies

11.4.1 General

Insulation deficiencies may result from insulation losing volume over the course of time and thereby not entirely filling the cavity in a frame wall.
An infrared camera allows you to see these insulation deficiencies because they either have a different heat conduction property than sections with correctly installed insulation, and/or show the area where air is penetrating the frame of the building.
When you are inspecting a building, the temperature difference between the inside and outside should be at least 10°C (18°F). Studs, water pipes, concrete columns, and simi­lar components may resemble an insulation deficiency in an infrared image. Minor differ­ences may also occur naturally.

11.4.2 Figure

In the image below, insulation in the roof framing is lacking. Due to the absence of insula­tion, air has forced its way into the roof structure, which thus takes on a different charac­teristic appearance in the infrared image.

11.5 Draft

11.5.1 General

Draft can be found under baseboards, around door and window casings, and above ceil­ing trim. This type of draft is often possible to see with an infrared camera, as a cooler airstream cools down the surrounding surface.
When you are investigating draft in a house, there should be sub-atmospheric pressure in the house. Close all doors, windows, and ventilation ducts, and allow the kitchen fan to run for a while before you take the infrared images.
An infrared image of draft often shows a typical stream pattern. You can see this stream pattern clearly in the picture below.
Also keep in mind that drafts can be concealed by heat from floor heating circuits.

11.5.2 Figure

The image below shows a ceiling hatch where faulty installation has resulted in a strong draft.

Thermographic measurement techniques

12 Thermographic measurement techniques

12.1 Introduction

An infrared camera measures and images the emitted infrared radiation from an object. The fact that radiation is a function of object surface temperature makes it possible for the camera to calculate and display this temperature.
However, the radiation measured by the camera does not only depend on the tempera­ture of the object but is also a function of the emissivity. Radiation also originates from the surroundings and is reflected in the object. The radiation from the object and the re­flected radiation will also be influenced by the absorption of the atmosphere.
To measure temperature accurately, it is therefore necessary to compensate for the ef­fects of a number of different radiation sources. This is done on-line automatically by the camera. The following object parameters must, however, be supplied for the camera:
• The emissivity of the object
• The reflected apparent temperature
• The distance between the object and the camera
• The relative humidity
• Temperature of the atmosphere

12.2 Emissivity

The most important object parameter to set correctly is the emissivity which, in short, is a measure of how much radiation is emitted from the object, compared to that from a per­fect blackbody of the same temperature.
Normally, object materials and surface treatments exhibit emissivity ranging from approx­imately 0.1 to 0.95. A highly polished (mirror) surface falls below 0.1, while an oxidized or painted surface has a higher emissivity. Oil-based paint, regardless of color in the visi­ble spectrum, has an emissivity over 0.9 in the infrared. Human skin exhibits an emissiv­ity 0.97 to 0.98.
Non-oxidized metals represent an extreme case of perfect opacity and high reflexivity, which does not vary greatly with wavelength. Consequently, the emissivity of metals is low – only increasing with temperature. For non-metals, emissivity tends to be high, and decreases with temperature.

12.2.1 Finding the emissivity of a sample

12.2.1.1 Step 1: Determining reflected apparent temperature
Use one of the following two methods to determine reflected apparent temperature:

Thermographic measurement techniques12
12.2.1.1.1 Method 1: Direct method
Follow this procedure:
1. Look for possible reflection sources, considering that the incident angle = reflection angle (a = b).
Figure 12.1 1 = Reflection source
2. If the reflection source is a spot source, modify the source by obstructing it using a piece if cardboard.
Figure 12.2 1 = Reflection source

Thermographic measurement techniques12
3. Measure the radiation intensity (= apparent temperature) from the reflection source using the following settings:
• Emissivity: 1.0
• D
: 0
obj
You can measure the radiation intensity using one of the following two methods:
Figure 12.3 1 = Reflection source Figure 12.4 1 = Reflection source
You can not use a thermocouple to measure reflected apparent temperature, because a thermocouple measures temperature, but apparent temperatrure is radiation intensity.
12.2.1.1.2 Method 2: Reflector method
Follow this procedure:
1. Crumble up a large piece of aluminum foil.
2. Uncrumble the aluminum foil and attach it to a piece of cardboard of the same size.
3. Put the piece of cardboard in front of the object you want to measure. Make sure that the side with aluminum foil points to the camera.
4. Set the emissivity to 1.0.
#T559828; r. AO/56381/56381; en-US
37
Thermographic measurement techniques12
5. Measure the apparent temperature of the aluminum foil and write it down. The foil is considered a perfect reflector, so its apparent temperature equals the reflected appa­rent temperature from the surroundings.
Figure 12.5 Measuring the apparent temperature of the aluminum foil.
12.2.1.2 Step 2: Determining the emissivity
Follow this procedure:
1. Select a place to put the sample.
2. Determine and set reflected apparent temperature according to the previous procedure.
3. Put a piece of electrical tape with known high emissivity on the sample.
4. Heat the sample at least 20 K above room temperature. Heating must be reasonably even.
5. Focus and auto-adjust the camera, and freeze the image.
6. Adjust Level and Span for best image brightness and contrast.
7. Set emissivity to that of the tape (usually 0.97).
8. Measure the temperature of the tape using one of the following measurement functions:
Isotherm (helps you to determine both the temperature and how evenly you have
heated the sample)
Spot (simpler)
Box Avg (good for surfaces with varying emissivity).
9. Write down the temperature.
10. Move your measurement function to the sample surface.
11. Change the emissivity setting until you read the same temperature as your previous measurement.
12. Write down the emissivity.
Note
• Avoid forced convection
• Look for a thermally stable surrounding that will not generate spot reflections
• Use high quality tape that you know is not transparent, and has a high emissivity you
are certain of
• This method assumes that the temperature of your tape and the sample surface are
the same. If they are not, your emissivity measurement will be wrong.

Thermographic measurement techniques12

12.3 Reflected apparent temperature

This parameter is used to compensate for the radiation reflected in the object. If the emissivity is low and the object temperature relatively far from that of the reflected it will be important to set and compensate for the reflected apparent temperature correctly.

12.4 Distance

The distance is the distance between the object and the front lens of the camera. This parameter is used to compensate for the following two facts:
• That radiation from the target is absorbed by the atmosphere between the object and
the camera.
• That radiation from the atmosphere itself is detected by the camera.

12.5 Relative humidity

The camera can also compensate for the fact that the transmittance is also dependent on the relative humidity of the atmosphere. To do this set the relative humidity to the cor­rect value. For short distances and normal humidity the relative humidity can normally be left at a default value of 50%.

12.6 Other parameters

In addition, some cameras and analysis programs from FLIR Systems allow you to com­pensate for the following parameters:
• Atmospheric temperature – i.e. the temperature of the atmosphere between the cam-
era and the target
• External optics temperature – i.e. the temperature of any external lenses or windows
used in front of the camera
• External optics transmittance – i.e. the transmission of any external lenses or windows
used in front of the camera

About calibration

13 About calibration

13.1 Introduction

Calibration of a thermal camera is a prerequisite for temperature measurement. The cali­bration provides the relationship between the input signal and the physical quantity that the user wants to measure. However, despite its widespread and frequent use, the term “calibration” is often misunderstood and misused. Local and national differences as well as translation-related issues create additional confusion.
Unclear terminology can lead to difficulties in communication and erroneous translations, and subsequently to incorrect measurements due to misunderstandings and, in the worst case, even to lawsuits.

13.2 Definition—what is calibration?

The International Bureau of Weights and Measures2defines calibration3in the following way:
an operation that, under specified conditions, in a first step, establishes a relation be­tween the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a meas­urement result from an indication.
The calibration itself may be expressed in different formats: this can be a statement, cali­bration function, calibration diagram
Often, the first step alone in the above definition is perceived and referred to as being “calibration.” However, this is not (always) sufficient.
Considering the calibration procedure of a thermal camera, the first step establishes the relation between emitted radiation (the quantity value) and the electrical output signal (the indication). This first step of the calibration procedure consists of obtaining a homo­geneous (or uniform) response when the camera is placed in front of an extended source of radiation.
As we know the temperature of the reference source emitting the radiation, in the second step the obtained output signal (the indication) can be related to the reference source’s temperature (measurement result). The second step includes drift measurement and compensation.
To be correct, calibration of a thermal camera is, strictly, not expressed through tempera­ture. Thermal cameras are sensitive to infrared radiation: therefore, at first you obtain a radiance correspondence, then a relationship between radiance and temperature. For bolometer cameras used by non-R&D customers, radiance is not expressed: only the temperature is provided.

13.3 Camera calibration at FLIR Systems

Without calibration, an infrared camera would not be able to measure either radiance or temperature. At FLIR Systems, the calibration of uncooled microbolometer cameras with a measurement capability is carried out during both production and service. Cooled cam­eras with photon detectors are often calibrated by the user with special software. With this type of software, in theory, common handheld uncooled thermal cameras could be calibrated by the user too. However, as this software is not suitable for reporting

About calibration13
purposes, most users do not have it. Non-measuring devices that are used for imaging only do not need temperature calibration. Sometimes this is also reflected in camera ter­minology when talking about infrared or thermal imaging cameras compared with ther­mography cameras, where the latter are the measuring devices.
The calibration information, no matter if the calibration is done by FLIR Systems or the user, is stored in calibration curves, which are expressed by mathematical functions. As radiation intensity changes with both temperature and the distance between the object and the camera, different curves are generated for different temperature ranges and ex­changeable lenses.
13.4 The differences between a calibration
performed by a user and that performed directly at FLIR Systems
First, the reference sources that FLIR Systems uses are themselves calibrated and traceable. This means, at each FLIR Systems site performing calibration, that the sour­ces are controlled by an independent national authority. The camera calibration certifi­cate is confirmation of this. It is proof that not only has the calibration been performed by FLIR Systems but that it has also been carried out using calibrated references. Some users own or have access to accredited reference sources, but they are very few in number.
Second, there is a technical difference. When performing a user calibration, the result is often (but not always) not drift compensated. This means that the values do not take into account a possible change in the camera’s output when the camera’s internal tempera­ture varies. This yields a larger uncertainty. Drift compensation uses data obtained in cli­mate-controlled chambers. All FLIR Systems cameras are drift compensated when they are first delivered to the customer and when they are recalibrated by FLIR Systems serv­ice departments.

13.5 Calibration, verification and adjustment

A common misconception is to confuse calibration with verification or adjustment. In­deed, calibration is a prerequisite for verification, which provides confirmation that speci­fied requirements are met. Verification provides objective evidence that a given item fulfills specified requirements. To obtain the verification, defined temperatures (emitted radiation) of calibrated and traceable reference sources are measured. The measure­ment results, including the deviation, are noted in a table. The verification certificate states that these measurement results meet specified requirements. Sometimes, compa­nies or organizations offer and market this verification certificate as a “calibration certificate.”
Proper verification—and by extension calibration and/or recalibration—can only be achieved when a validated protocol is respected. The process is more than placing the camera in front of blackbodies and checking if the camera output (as temperature, for in­stance) corresponds to the original calibration table. It is often forgotten that a camera is not sensitive to temperature but to radiation. Furthermore, a camera is an imaging sys­tem, not just a single sensor. Consequently, if the optical configuration allowing the cam­era to “collect” radiance is poor or misaligned, then the “verification” (or calibration or recalibration) is worthless.
For instance, one has to ensure that the distance between the blackbody and the camera as well as the diameter of the blackbody cavity are chosen so as to reduce stray radiation and the size-of-source effect.
To summarize: a validated protocol must comply with the physical laws for radiance, and not only those for temperature.

About calibration13
Calibration is also a prerequisite for adjustment, which is the set of operations carried out on a measuring system such that the system provides prescribed indications corre­sponding to given values of quantities to be measured, typically obtained from measure­ment standards. Simplified, adjustment is a manipulation that results in instruments that measure correctly within their specifications. In everyday language, the term “calibration” is widely used instead of “adjustment” for measuring devices.

13.6 Non-uniformity correction

When the thermal camera displays ”Calibrating…” it is adjusting for the deviation in re­sponse of each individual detector element (pixel). In thermography, this is called a ”non­uniformity correction” (NUC). It is an offset update, and the gain remains unchanged.
The European standard EN 16714-3, Non-destructive Testing—Thermographic Testing —Part 3: Terms and Definitions, defines an NUC as “Image correction carried out by the camera software to compensate for different sensitivities of detector elements and other optical and geometrical disturbances.”
During the NUC (the offset update), a shutter (internal flag) is placed in the optical path, and all the detector elements are exposed to the same amount of radiation originating from the shutter. Therefore, in an ideal situation, they should all give the same output sig­nal. However, each individual element has its own response, so the output is not uniform. This deviation from the ideal result is calculated and used to mathematically perform an image correction, which is essentially a correction of the displayed radiation signal. Some cameras do not have an internal flag. In this case, the offset update must be per­formed manually using special software and an external uniform source of radiation.
An NUC is performed, for example, at start-up, when changing a measurement range, or when the environment temperature changes. Some cameras also allow the user to trig­ger it manually. This is useful when you have to perform a critical measurement with as little image disturbance as possible.
13.7 Thermal image adjustment (thermal
tuning)
Some people use the term “image calibration” when adjusting the thermal contrast and brightness in the image to enhance specific details. During this operation, the tempera­ture interval is set in such a way that all available colors are used to show only (or mainly) the temperatures in the region of interest. The correct term for this manipulation is “ther­mal image adjustment” or “thermal tuning”, or, in some languages, “thermal image optimi­zation.” You must be in manual mode to undertake this, otherwise the camera will set the lower and upper limits of the displayed temperature interval automatically to the coldest and hottest temperatures in the scene.
