BEFORE USE
Before first use, please connect the power cord as shown in the
picture.
IMPORTANT SAFETY INFORMATION
Please read and follow all instructions and safety guidelines in this manual.
- Do not point the device at another person or animal.
- Do not point the device at an aircraft.
- Avoid any eye contact with the laser. Laser radiation may cause eye damage.
- Do not allow children to operate the device.
- Do not use the device to determine whether a highly reflective surface is safe to touch. Temperature measurement may be inaccurate, which may cause burns.
- Keep the device away from objects that produce strong electromagnetic fields, such as arc welders and induction heaters.
- The device measures surface temperature, not internal temperature. Do not use the device to measure body temperature.
- Do not expose the device to direct sources of heat for extended periods of time.
- Do not use the device near explosive gases or other potentially explosive areas.

OPERATION INTRODUCTION
A. Laser pointer on/off button
- Short press to turn on/off laser pointer.
- When the laser pointer is turned on, press the TEST button and you will see two red laser points that can be used to aim at the object being measured.
B. Mode switch button
- Short press to switch the 7 measurement modes. When switching, the screen will display the following symbols: REC – MAX – MIN – DIF – AVG – HAL – LAL.
- INTRODUCTION OF THE 7 MODES:
| Mode Symbols | Mode Name | Mode Function |
|---|---|---|
| REC | Data storage mode | 12 sets of data can be recorded in a loop. |
| MAX | Max value mode | the maximum value of the current measurement data can be |
displayed continuously.
MIN| Min value mode| the minimum value of the current measurement data can be
displayed continuously.
DIF| Difference mode| the difference between the maximum and minimum values
can be displayed continuously.
AVG| Average value mode| the average value of all current measurement data is
calculated.
HAL| High temperature alarm value setting mode| the high temperature alarm
value can be adjusted by using the UP/DN buttons.
LAL| Low temperature alarm value setting mode| the low temperature alarm value
can be adjusted by using the UP/DN buttons.
C. Backlight on/off & up button
- When in MAX, MIN, DIF, and AVG mode, short press to turn on/off backlight.
- When in HAL and LAL mode, short press to increase a value, long press to increase the value quickly and continuously.
- When in REC mode, short press to return to the previous page.
D. Emissivity adjust & flashlight on/off button
- Short press to adjust emissivity. When the “ E=” symbol flashes on the screen, you can press the UP/DN button to adjust the emissivity value. Press again to exit the adjustment emissivity, the E= symbol is steady on.
- Long press to turn on/off the flashlight in front of the lens.
E. Power on & measure button
Short press to power on. After turning on, short press to measure the
temperature of the object, and long press can scan and measure.
F. Temperature unit switch & down button
- When in MAX, MIN, DIF, and AVG mode, short press to switch the temperature unit(°F/°C).
- When in HAL and LAL mode, short press to decrease a value, long press to decrease the value quickly and continuously.
- When in REC mode, short press to return to the next page.

DISTANCE-TO-SPOT RATIO
The distance-to-spot ratio (D:S) determines the accuracy of the reading taken
by the device. The smaller the surface you want to measure, the closer you
should hold the device to the surface.
The device’ s 30:1 D:S ratio means that when held 300 inches from a surface,
the device measuresa “spot” thatis 10 inch in diameter. When the device is
held 900 inches away, the “spot” will be 30 inches, and so on. The greater the
distance, the larger the measured surface area.For best results, make sure the
surface that you want to measure is at least twice the size of the spot the
device is measuring. If the measured spot is too small, the device’ s reading
will be less accurate. The device’ s reading may also be less accurate when
measuring a larger surface because the temperature will vary more over a
larger surface. 
EMISSIVITY
Emissivity measures how well a surface emits thermal or infrared energy,
ranging from 0.00-1.00. Non-reflective surfaces have a higher emissivity
(closer to 1) and reflective surfaces have a lower emissivity (closer to 0).
This infrared thermometer is meant for high-emissivity surfaces, and may not
accurately measure polished, shiny, or reflective surfaces.
To take accurate temperature measurements of reflective surfaces with low
emissivity, adjust the emissivity value before measurement using the
Emissivity Reference Chart. Optionally, place a strip of masking tape over the
surface and allow it to adjust to the surface temperature for 30 minutes.
Then, measure the taped section to increase temperature reading accuracy.
