Batteries
1. Remove thescrew from thebattery cover and open
thebattery compartment.
2. Insert 4×AA/LR6 batteries (sold separately).
Follow themarkings inside thebattery compartment
to ensure thecorrect polarity.
3. Close the cover and refit the screw.
Note: The camera can also be powered using
theMicro-USB port. Remove thebatteries from
thecamera and connect aUSB charger or power bank
(max 5 V) to theMicro-USB port on thecamera (8).
Buttons and functions
• [ ] A long press of theon/off button will turn thecamera on or off, ashort press
will return to theprevious position in themenu.
• [MODE ] A single short press will open and enter menu selections. A second short
press will confirm your selection/settings.
• [ ▲ ]Move up in themenu. In measuring mode, this button switches theLED light
on and off.
• [ ▼ ]Move down in themenu. Each short press of thebutton will increase theamount
of theinfrared heat map images blended with thevisual images by 25%.
Taking photographs
Information: In order for thecamera to be able to take photos and store them,
it needs to be fitted with aMicroSD memory card (with a 8 GB MicroSD card you can
take 50,000 photos).
1. Pull thetrigger (4) to take ascreenshot of thetemperature readings on thedisplay.
2. The image and thewords “YES” and “NO” will appear on thedisplay.
3. Press [ ▲ ]to save theimage on thememory card.
4. Press [ ▼ ]to delete theimage.

Instructions for use
Things to consider when measuring temperature with thethermal imaging camera
• The most common application for athermal imaging camera is to use it to see
thehot and cold areas and temperature differences around awindow, in awall cavity
or radiator for example. The colours on thedisplay show hot (red) and cold (blue)
areas (if thecolour palette of thecamera has been set to red/blue). The different
colours make it easier to see theareas on thecamera display having different
temperatures and this is usually more important than theactual temperatures.
• The colours on theimage only show which part of area is cold and which part is hot.
The blue area in one heat map image need not necessarily have thesame
temperature as ablue area in another heat map image. The blue colour only
shows which part of theimage is colder compared to therest of theimage.
If you would like to measure thetemperature, there are some things you need to consider:
• In simple terms, you could say that thethermal imaging camera registers
theinfrared (IR) radiation anobject emits.
• Temperature measurement depends on theemission factor of theobject. The emission
factor is ameasure of thecapacity of amaterial (object) to emit infrared radiation.
• The emission factor differs between materials and is influenced by surface colour
and texture.
• In order to achieve more accurate temperature measurements, it is therefore
necessary to set theemission factor of thecamera to suit thematerial and surface
texture of theobject being measured.
• The camera menu has afunction for setting theemission factor. The camera has
4 set values: 0.95, 0.80, 0.60, 0.30 and amenu where you can select your own
emission factor from 0.10 to 1.00.

The table below shows theapproximate emission factor of some materials.
Material
Aluminium, non-oxidised 0.02
Concrete 0.93
Iron, emery abraded 0.24
Iron with rolling skin 0.77
Wood 0.94
Radiator, black anodised 0.98
Plastic: PE, PP, PVC 0.94
Masonry 0.93
Paper 0.97
Porcelain 0.92
Bricks, mortar, plaster 0.93
As can be seen from the table, 0.95 is a good average emission factor for most materials.
• The emission factor of amaterial is also influenced by surface colour and texture.
• It can be difficult to achieve areliable reading on wet surfaces or surfaces covered
in snow or frost.
• It is also difficult to get anaccurate reading on dirty and contaminated surfaces.
Air pockets can create misleading measurement results.
• Dark, matt surfaces will emit more thermal radiation than bright, smooth surfaces.
• Take into consideration any possible sources of radiation, especially when
measuring smooth surfaces (e.g. sunshine, radiators).
Care and maintenance
• Clean theproduct by wiping it with adry cloth.
• Whenever thecamera is not to be used for anextended period, thebatteries
should be removed and it should be stored in adry, dust-free environment.
