In the circumstances that such conditions are not met or not fully understood, please do not continue to perform any operation indicated by the warning mark.

Introduction

The infrared thermometer is suitable for non-contact temperature measurement. The thermometer determines the surface temperature of the object by measuring the infrared energy of the radiation from the surface of the object.

Safety Operation Specifications

WARNING

To prevent eye injury or personal injury：

• Please read the manual carefully before using the product.
• Please do not look at the laser directly. Do not direct laser direct to humans or animals or indirectly from the reflecting surface.
• If the instrument works abnormally, do not use.
• Do not use optical tools (such as binocular, telescope, microscope, etc.) to look directly at the laser. Optical tools may focus on lasers, thereby damaging the eyes.
• Replace battery when indication of battery power is insufficient, so as to prevent measurement error.
• Do not use products in the environment of explosive gas, water vapor or dust.
• For actual temperature, please refer to the emissivity information. Reflective objects will cause the measured temperature to be lower than the actual temperature. These objects are dangerous to burn.
• Do not put the thermometer near or put it on a high temperature object
• Please be sure to use the meter according to the regulations, otherwise the protection function provided by the product may be weakened.
• Do not use a solvent cleaning thermometer

Caution

To avoid damaging the thermometer or the tested equipment, please protect it from the following effects:

• Electromagnetic field and static electricity of arc welding machine, induction heater and other equipment.
• Thermal shock (when a sudden change in ambienttemperature

• Do not put the thermometer near or put it on a high temperature object.
• Keep the thermometer clean and avoid dust entering the barrel.

Operating thermometer

Alarm upper limit setting

1. Press key and hold for more than 2 seconds. The meter
   enters the set state.

2. Press key(≤1Sec.) Switch to alarm upper limit set state， display the “Hi”. And display the current alarm upper limit value.

3. Press“▲/▼”key increase or decrease the set value, press and hold key to increase or decrease the set value quickly.

4. Press trigger switch， or press key and hold for more than 2seconds, exit settings

Alarm low limit setting

1. Press key and hold for more than 2 seconds. The meter enters the set state.
2. Press key(≤1Sec.) Switch to alarm low limit set state， display the “Low”. And display the current alarm low limit value.
3. Press“▲/▼”key increase or decrease the set value, press and hold key to increase or decrease the set value quickly.
4. Press trigger switch，or press key and hold for more than 2seconds, exit settings

Emittance setting

1. Press key and hold for more than 2 seconds. The meter enters the set state.
2. Press key( ≤ 1Sec.) Switch to emittance set state ， Emittance display area scintillation display.
3. Press“▲/▼”key increase or decrease the set value, press and hold key to increase or decrease the set value quickly.
4. Press trigger switch，or press key and hold for more than 2seconds, exit settings

Temperature unit setting

2. Press key(≤1Sec.) Switch to temperature unit set state， unit scintillation display.
3. Press“▲/▼”key Selection of temperature units.
4. Press trigger switch，or press key and hold for more than 2seconds, exit settings

Laser on or off

Press key(≤1Sec.)to turn on laser, press again to turn off laser. When laser turn on, LCD display” ”。

Backlight on or off:
Press * key(≤1Sec.)to turn on backlight, press again to turn off backlight.

Non-contact temperature measurement

Aim at the measured object with the thermometer and pull the trigger to keep the temperature continuously measured. Loosen the trigger and keep the result of the measurement.
When measuring, a laser pointer can be used to help the thermometer aim.

Maximum value of the meter shows the maximum value of the measurement temperature.。
The instrument alarm indicator is red when the measured value is greater than the set temperature upper limit alarm value or the measured value is less than the set temperature lower limit alarm value.。

Note

• Attention should be paid to distance and spot diameter ratio and field of view (see target distance ratio).
• Laser is used only for aim and is independent of temperature measurement.
• After 30 seconds without any operation, the thermometer will be turned off automatically. If you need to start a thermometer, pull the trigger.

Target distance ratio (D:S ratio)
The thermometer has a certain angle of view and field of view, as shown in the following figure.

Make sure the object under test is full of the field of view of the thermometer, that is, let the thermometer “see” only the object under test and “not see” other objects. The larger the object is, the farther the distance can be measured; the smaller the object, the closer the distance must be. The ratio of the measured distance to the measured target size is D:S ratio of 12: 1, as shown in the following figure：

Infrared radiation rate of object

The radiant rate represents the ability of an object to radiate infrared radiation. The greater the radiation rate, the stronger the radiation ability of the object surface. The emissivity of most organic or metal oxide surfaces is between 0.85~0.98. The emissivity of the thermometer is 0.95. The emissivity of the instrument should be consistent with the emissivity of the measured object when measuring. Attention should be paid to the effect of radiation on measurement results.

Maintain Replace the battery

WARNING

Batteries contain dangerous chemicals that may cause burns or explosions. If you are exposed to chemicals, wash or seek medical advice with water. To prevent injury and ensure safety work and maintenance.

• Do not disassemble the battery.
• If battery leakage occurs, please repair it and use it first.
• If the meter is not used for a long time, please remove the battery to prevent the battery from leaking and damage the instrument.
• Please make sure that the battery is correct in order to prevent the battery leakage.
• Do not connect the battery terminals together. Do not disconnect or squeeze the battery.
• Do not store batteries in containers that may cause short circuit terminals.
• Do not place the battery near the heat source or the fire source. Do not shine under the sun.

When the battery power is insufficient, the meter displays the ” ” symbol and the battery must be replaced at this time. Open the battery cover with your hands, replace the new battery with the same specifications, and then close the battery cover tightly. As shown.

Clean lens tube
Use clean air to remove dust particles from the lens barrel. Carefully wipe the surface with a cotton swab dipped in water.

Surface Clean
Wet the sponge or soft cloth with soap and water. Do not use abrasives or solvents。

CAUTION
To avoid damaging the thermometer, do not immerse it in water. Do not use corrosive cleaners, otherwise they will damage the shell.
