1 - Introduction
Overview
The Thermal Imager is handheld imaging camera used for predictive maintenance, equipment troubleshooting, and verication.
Thermal and visual images are displayed on the LCD and can be saved to a Micro SD Memory card. Transferring Images to
a PC is accomplished by removing the SO memory card and connecting it to a PC through the included card reader.
In addition to the features mentioned above, the Thermal Imager provide video recording with audio and play back.
2 - Safely Information
To prevent eye damage and personal injury, do not look into the laser. Do not point laser directly at persons or animals or
indirectly off reective surfaces.
Do not disassemble or do a modication to the Thermal Imager.
Do not point the Thermal Imager (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 Thermal Imager.
Do not use the Thermal Imager in a temperature higher than +50°C (+122°F), lower than -20°C (-4°F). High temperature or low
temperature can cause damage to the Thermal Imager.
Only use the correct equipment to discharge 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 ow of current to the battery can occur. This can cause the battery to become hot, or cause an
explosion and injury to persons.
Do not pull out the battery when the thermal imager is working.
If you pull out the battery when the thermal imager is working, may cause the thermal imager work unnormal.
Do not disassemble or do a modication to the battery.
The battery contains safety and protection devices which, if they become damaged, can cause the battery to become hot, or
cause an explosion or an ignition. If there is a leak from the battery and the uid gets into your eyes, do not rub your eyes. Flush
well with water and immediately get medical care.
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 battery in or near a re, or in direct sunlight, or other high-temperature locations. Do not solder directly onto the
battery.
Always charge the battery in the special temperature rang.
The temperature range through which you can charge the battery is 0°C to +50°C (+32°F to +122°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.
Do not get water or salt water on the battery, or permit the battery to get wet.
Clean the case with a damp cloth and a weak soap solution. Do not use abrasives, isopropyl alcohol, or solvents to clean the
case or lens/screen.
Be careful when you clean the infrared lens. Do not clean the infrared lens too vigorously. This can damage the anti-reective
coating.
Avoid condensation
Take the Thermal Imager from cold to hot, it will appear condensation in thermal Imager. To protect the Thermal Imager, you
should power of the Thermal Imager, wait until the Thermal Imager has become war enough for the condensation to evaporate.
Storage
If you do not use the Thermal Imager, put the Thermal Imager in cool and dry environment, if you store Thermal Imager
equipped with the battery, the power of the battery will be exhausted.

6 - Before You Start
6.1 - How to Charge the Battery
Before you use tile Thermal Imager for tile rst time, charge the battery for minimum of one and one-half hours. The battery
status shows on the four-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 light is off.
3 - Disconnect ac power adapter when the battery is full 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 decreased.
6.2 - Power On and Off
To turn the Thermal Imager on, push the Power Button. When Thermal Imagers power on, Push and hold the Power
Button for two seconds, turn the Thermal Imager off.
Note
The Thermal Imager needs sufcient warm-up time for the most accurate temperature measurements and best image quality.
This time can often vary by environmental conditions. It is best to wait a minimum of 10 minutes If tile most accurate temperature
measurements very Important to your application.

6.4 - 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.
IFOV (Instantaneous Reid 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);
D: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 34um. Horizontal FOV is 17°, Vertical FOV
is 17°, the IFOV is
34um/9mm = 3.78mrad;
D:S theoretical (=1 / IFOV theoretical) = 265:1
Spot Size= 100.00cm*100.00cm
(Based upon IFOVtheoretical)
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 need 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.
6.5 - 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
