6. Before You Start
6.1. How to Charge the Battery
• Before you use the Thermal Imager for the first time, charge the battery
for three and a half hours.
• The battery status shows on the six-segment charge indicator.
• To charge the battery, use follow before:
1. Connect the ac power adapter into an AC wall outlet and connect the
DC output to the Thermal Imager’s AC power socket. The charge light
is on, The battery indicator becomes " " while the
battery charges with the AC power adapter.
2. Charge until the charge indicator becomes " " the charge icon will not
change.
3. Disconnect AC power adapter when the battery is fully charged.
Note: Make sure that the Thermal Imager is near room temperature before
you connect it to the charger. Do not charge in hot or cold areas. When you
charge in extreme temperature, battery capacity may be damaged.
6.2. Power On
To turn the Thermal Imager on, push the Power/Lock " " Button for
about 2 seconds.
Note: After turning on the device, the thermal Imager needs sufficient
warm-up time for the most accurate temperature measurements and best
image quality. So the visible image will first appear, and the thermal sensor
will calibrate internal for several seconds. After that the thermal image will
be displayed on the screen.

6.5. Lens
• The Thermal Imager has a Lens.
• FOV is the largest area that your Imager can see at a set distance.
• This table lists the horizontal FOV, vertical FOV and IFOV for lens.
Focal Length Horizontal FOV Vertical FOV IFOV
7.5mm 20.7° 15.6° 2.26mrad
• IFOV (Instantaneous Field of View) is the smallest detail within the FOV
that can be detected or seen at a set distance, the unit is rad, The
formula is this: IFOV=(Pixel Size)/(Lens focal length).
• O:S theoretical(= 1/IFOV theoretical) is the calculated spot size based on
the pixel size of the Thermal Imager detector array and lens focal length.
Example: If Thermal Imager uses 9mm lens, because the Pixel Size of
detector is 17μm, Horizontal FOV is 20.7°,Vertical FOVis 15.6°, the IFOVis
17μm/7.5mm=2.26mrad; O:S theoretical (=1/ IF0Vtheoretical)=442:1.
• D:S measure (= 1/IFOV measure) is the spot size needed
to provide an accurate temperature measure.
• Typically D:S measure is 2 to 3 times smaller than D:S theoretical, which
means the temperature measurement area of the target needs to be 2 to
3 times larger than that determined by the calculated theoretical D:S.
Note: IFOV theoretical represents the smallest objects that the thermal
imager can detect or see. IFOV measure represents the smallest object
form which an accurate temperature can be measured by the thermal
imager.

13
6.6. Focus
• To adjust focus, clockwise or Anti-clockwise rotates the IR Lens.
• When target comes into focus, it shows a sharper image.
• When the target moves out of focus, the thermal image becomes blurry.
Note: Correct focus is important in all imaging applications. Correct focus
makes sure that the infrared energy is correctly directed onto the pixels of
the detector. Without the correct focus, the thermal image can be blurry
and the radiometric data will be inaccurate. Out-of-focus infrared images
are frequently unusable or of little value.
6.7. Shutter
• The thermal image of the Thermal Imager becomes blurry, when the
Thermal Imager is not correcting after some minutes or the Thermal
Imager changes target.
• To get a clearer thermal image, the Thermal Imager will correct itself.
• The Thermal Imager has two modes for correcting, Manual and Auto
mode.
• In Manual Mode, hold down the down arrow button, the Thermal Imager
will correct.
• In Auto Mode, the Thermal Imager can correct automatically while the
thermal image of the Thermal Imager becomes blurry.
6.8. Temperature Measurement
• All objects radiate infrared energy.
• The quantity of energy radiated is base on the actual surface temperature
and the surface emissivity of the object.
• The Thermal Imager senses the infrared energy from the surface of the
object and uses this data to calculate an estimated temperature value.
• Many common objects and materials such as painted metal, wood, water,
skin, and cloth are very good at radiating energy and it is easy to get
relatively accurate measurements.
• For surfaces that are good at radiating energy (high emissivity). The
emissivity factor is >0.90.

14
• This simplification does not work on shiny surfaces or unpainted metals
as they have an emissivity of <0.6. These materials are not good at
radiating energy and are classified as low emissivity.
• To more accurately measure materials with a low emissivity, an emissivity
correction is necessary.
• Adjustment to the emissivity setting will usually allow the Thermal
Imager to calculate a more accurate estimate of the actual temperature.
• For more information please see Emissivity Adjustment to get the most
accurate temperature measurements.
6.9. Emissivity Adjustment
• The correct emissivity value is important to make the most accurate
temperature measurement.
• Emissivity of a surface can have a large effect on the apparent
temperatures that the Thermal Imager observes.
• Understanding the emissivity of the surface, but may not always, allow
you to obtain more accurate temperature measurements.
Note: Surfaces with an emissivity of <0.60 make reliable and consistent
determination of actual temperature problematic. The lower the emissivity,
the more potential error is associated with the Imager’s temperature
measurement calculations. This is also true even when adjustments to the
emissivity and reflected background adjustments are performed properly.
• Emissivity is set directly as a value or from a list of emissivity values for
some common materials.
• The global emissivity displays in LCD Screen as E=x.xx.
• The following table gives typical emissivity of important materials:
6.10. Reflected Temperature
• Using the offset factor, the reflection is calculated out due to the low
emissivity and the accuracy of the temperature measurement with
infrared instruments is improved.
Material Emissivity
Water 0.96
Stainless Steel 0.14
Aluminum Plate 0.09
Asphalt 0. 96
Concrete 0. 97
Cast Iron 0.81
Rubber 0.95
Wood 0.85
Brick 0.75
Material Emissivity
Tape 0. 96
Brass Plate 0.06
Human Skin 0.98
PVC Plastic 0. 93
Polycarbonate 0.80
Oxidized Copper 0.78
Rust 0.80
Paint 0. 90
Soil 0.93

15
• In most cases, the reflected temperature is identical to the ambient air
temperature.
• Only when objects with strong emissions with much higher temperature
are in the proximity of the object being measured should be determined
and used.
• The reflected temperature has only little effect on objects with high
emissivity.
• The reflected temperature can be set individually.
• Follow these steps to get the right value for the reflected temperature.
1. Set the emissivity to 1.0.
2. Adjust the optical lens to near focus.
3. Looking in the opposite direction away from the object, take a
measurement and freeze the image.
4. Determine the average value of the image and use that value for your
input of reflected temperature.
6.11. Thermal Imager Reporter Software
• Thermal Imager Reporter software is supplied with the Thermal Imager.
• This Software is intended for Thermal Imager and contains feature to
analyze images, organize data and information, and make professional
reports.
• Thermal Imager Reporter software allows audio annotations and
commentary to be reviewed on a PC.
