• Do not point the infrared camera (with or without the lens cover) at intensive energy sources, for example devices that emit 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.
• Do not use the camera in a temperature higher than +50°C (+122°F), unless specified otherwise in the user documentation. High temperatures can cause damage to the camera.
• (Applies only to cameras with laser pointer:) Protect the laser pointer with the protec­tive cap when you do not operate the laser pointer.
• Applies only to cameras with battery:
• Do not attach the batteries directly to a car’s cigarette lighter socket, unless a spe-
cific adapter for connecting the batteries to a cigarette lighter socket is provided by FLIR Systems.
• Do not connect the positive terminal and the negative terminal of the battery to
each other with a metal object (such as wire).
• Do not get water or salt water on the battery, or permit the battery to get wet.
• Do not make holes in the battery with objects. Do not hit the battery with a hammer.
Do not step on the battery, or apply strong impacts or shocks to it.
• Do not put the batteries in or near a fire, or into direct sunlight. When the battery
becomes hot, the built-in safety equipment becomes energized and can stop the battery charging process. If the battery becomes hot, damage can occur to the safety equipment and this can cause more heat, damage or ignition of the battery.
• Do not put the battery on a fire or increase the temperature of the battery with heat.
• Do not put the battery on or near fires, stoves, or other high-temperature locations.
• Do not solder directly onto the battery.
• Do not use the battery if, when you use, charge, or store the battery, there is an un-
usual smell from the battery, the battery feels hot, changes color, changes shape, or is in an unusual condition. Contact your sales office if one or more of these prob­lems occurs.
• Only use a specified battery charger when you charge the battery.
• The temperature range through which you can charge the battery is ±0°C to +45°C
(+32°F to +113°F), unless specified otherwise in the user documentation. 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.
• The temperature range through which you can discharge the battery is −15°C to
+50°C (+5°F to +122°F), unless specified otherwise in the user documentation. Use of the battery out of this temperature range can decrease the performance or the life cycle of the battery.
• When the battery is worn, apply insulation to the terminals with adhesive tape or
similar materials before you discard it.
• Remove any water or moisture on the battery before you install it.
• Do not apply solvents or similar liquids to the camera, the cables, or other items. This can cause damage.
• Be careful when you clean the infrared lens. The lens has a delicate anti-reflective coating.
• Do not clean the infrared lens too vigorously. This can damage the anti-reflective coating.

WARNING, CAUTION
• In furnace and other high-temperature applications, you must mount a heatshield on the camera. Using the camera in furnace and other high-temperature applications without a heatshield can cause damage to the camera.
• (Applies only to cameras with an automatic shutter that can be disabled.) Do not dis­able the automatic shutter in the camera for a prolonged time period (typically max. 30 minutes). Disabling the shutter for a longer time period may harm, or irreparably damage, the detector.
• The encapsulation rating is valid only when all openings on the camera are sealed with their designated covers, hatches, or caps. This includes, but is not limited to, compartments for data storage, batteries, and connectors.
• (Applies only to FLIR A3xx f/A3xx pt series cameras.)
• Except as described in this manual, do not open the FLIR A3xx pt/A3xx f series
camera for any reason. Disassembly of the camera (including removal of the cover) can cause permanent damage and will void the warranty.
• Do not to leave fingerprints on the FLIR A3xx pt/A3xx f series camera’s infrared
optics.
• The FLIR A3xx f series camera requires a power supply of 21–30 VDC. Operating
the camera outside of the specified input voltage range or the specified operating temperature range can cause permanent damage.
• The FLIR A3xx pt series camera requires a power supply of 21–30 VAC or 21–30
VDC. Operating the camera outside of the specified input voltage range or the specified operating temperature range can cause permanent damage.
• When lifting the FLIR A3xx pt series camera use the camera body and base, not
the tubes.
• (Applies only to FLIR GF309 cameras.) CAUTION: The exceptionally wide tempera­ture range of the FLIR GF309 infrared camera is designed for performing highly accu­rate electrical and mechanical inspections and can also “see through flames” for inspecting gas-fired furnaces, chemical heaters and coal-fired boilers. IN ORDER TO DERIVE ACCURATE TEMPERATURE MEASUREMENTS IN THESE ENVIRON­MENTS THE GF309 OPERATOR MUST HAVE A STRONG UNDERSTANDING OF RADIOMETRIC FUNDAMENTALS AS WELL AS THE PRODUCTS AND CONDI­TIONS OF COMBUSTION THAT IMPACT REMOTE TEMPERATURE MEASURE­MENT. The Infrared Training Center (itc) offers a wide range of world class infrared training for thermography professionals including GF309 operators. For more informa­tion about obtaining the training and certification you require, contact your FLIR sales representative or itc at www.infraredtraining.com.

Working with image modes

16.1 What is picture-in-picture?

Picture-in-picture is similar to thermal fusion in that it lets you display part of a digital pho­to as an infrared image.
However, picture-in-picture displays an infrared image frame on top of a digital photo.

16.2 What is thermal fusion?

Thermal fusion is a function that lets you display part of a digital photo as an infrared image.
For example, you can set the camera to display all areas of an image that have a certain temperature in infrared, with all other areas displayed as a digital photo.

16.3 Types

The number of image modes is subject to camera models. These include:
Above: All areas in the digital photo with a temperature above the specified tempera­ture level are displayed in infrared.
Below: All areas in the digital photo with a temperature below the specified tempera­ture level are displayed in infrared.
Interval: All areas in the digital photo with a temperature between two specified tem­perature levels are displayed in infrared.
Picture-in-Picture: An infrared image frame is displayed on top of the digital photo.
MSX (Multi Spectral Dynamic Imaging): Using this mode, the camera captures infra­red images where the edges of the objects are enhanced.
Note
These image modes only work correctly for calibrated lenses. The lens that ships with the camera is factory-calibrated. To have a new lens calibrated, your must send in the camera and the lens to your lo­cal service department.

17.6 Changing object parameters

17.6.1 General

For accurate measurements, you must set the object parameters.

17.6.2 Types of parameters

The camera can use these object parameters:
Emissivity, i.e., how much radiation an object emits, compared with the radiation of a
theoretical reference object of the same temperature (called a “blackbody”). The op­posite of emissivity is reflectivity. The emissivity determines how much of the radiation originates from the object as opposed to being reflected by it.
Reflected apparent temperature, which is used when compensating for the radiation
from the surroundings reflected by the object into the camera. This property of the ob­ject is called reflectivity.
Object distance, i.e., the distance between the camera and the object of interest.
Atmospheric temperature, i.e., the temperature of the air between the camera and the
object of interest.
Relative humidity, i.e., the relative humidity of the air between the camera and the ob-
ject of interest.
External IR window compensation, i.e., the temperature of any protective windows,
etc., that are set up between the camera and the object of interest. If no protective window or protective shield is used, this value is irrelevant and should be left inactive.

17.6.3 Recommended values

If you are unsure about the values, the following are recommended:
Emissivity 0.95
Object distance 1.0 m (3.3 ft.)
Reflected apparent temperature +20°C (+69°F)
Relative humidity 50%
Atmospheric temperature +20°C (+69°F)

17.6.4 Procedure

18.6 Typical moisture measurement and documentation procedure

18.6.1 General

The following procedure can form the basis for other procedures using Extech meters and infrared cameras.

18.6.2 Procedure

Follow this procedure:
1. Use the infrared camera to identify any potential damp areas behind walls and ceilings.
2. Use the moisture meter to measure the moisture levels at various suspect locations that may have been found.
3. When a spot of particular interest is located, store the moisture reading in the mois­ture meter’s memory and identify the measurement spot with a handprint or other thermal identifying marker.
4. Recall the reading from the meter memory. The moisture meter will now continuously transmit this reading to the infrared camera.
5. Use the camera to take a thermal image of the area with the identifying marker. The stored data from the moisture meter will also be saved on the image.

Annotating images

20.1 General

This section describes how to save additional information together with an infrared image by using annotations.
Using annotations makes reporting and post-processing more efficient by providing es­sential information about the image, e.g., conditions, photos, and information about where an image is taken.
You can set the camera to automatically add an annotation to your images.
Note
Many of the procedures in this section assume that the camera is set to preview images before saving
them. If it is not, use the joystick to go to

20.2 Taking a digital photo

Application examples

28.1 Moisture & water damage

28.1.1 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.
Note
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.

28.1.2 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.

28.2 Faulty contact in socket

28.2.1 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.
Note
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.

28.2.2 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.

Page 87
Application examples28

28.3 Oxidized socket

28.3.1 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.
Note
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.

28.3.2 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.

Application examples28

28.4 Insulation deficiencies

28.4.1 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.
Note
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.

28.4.2 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.

Application examples28

28.5 Draft

28.5.1 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.
Note
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.

28.5.2 Figure

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

Thermographic measurement techniques

31.1 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

31.2 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.

31.2.1 Finding the emissivity of a sample

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

86
Page 97
Thermographic measurement techniques31
31.2.1.1.1 Method 1: Direct method
Follow this procedure:
1. Look for possible reflection sources, considering that the incident angle = reflection angle (a = b).
Figure 31.1 1 = Reflection source
2. If the reflection source is a spot source, modify the source by obstructing it using a piece if cardboard.
Figure 31.2 1 = Reflection source
#T559598; r. AB/ 9443/9443; en-US
87
Page 98
Thermographic measurement techniques31
3. Measure the radiation intensity (= apparent temperature) from the reflecting 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 31.3 1 = Reflection source
Note
Using a thermocouple to measure reflected apparent temperature is not recommended for two impor­tant reasons:
• A thermocouple does not measure radiation intensity
• A thermocouple requires a very good thermal contact to the surface, usually by gluing and covering the sensor by a thermal isolator.
31.2.1.1.2 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.
5. Measure the apparent temperature of the aluminum foil and write it down.

Thermographic measurement techniques31
31.2.1.2 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.

31.3 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.

31.4 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.

31.5 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%.

31.6 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 cam­era and the target
• External optics temperature – i.e. the temperature of any external lenses or windows used in front of the camera
