Mini Infrared Thermometer

Please read these instructions carefully before use and retain for future reference.

• Please operate according to this manual, otherwise the protection provided by the

device will be impaired or fail.

• Do not point laser directly in your eyes or indirectly off reective surfaces.

• Check the condition before using. If you nd any cracking, breakage, damage or

abnormality, or you consider the device broken, stop using the device immediately

• Do not use the Thermometer if it operates abnormally. Protection may be impaired.

When in doubt, have the Thermometer serviced.

• Do not operate the Thermometer around explosive gas, vapour, or dust.

• To avoid a burn hazard, remember that highly reective objects will often result in

lower than actual temperature measurements.

• To avoid damaging the thermometer or the equipment under test protect them from

the following:

EMF (electro-magnetic elds) from arc welders, induction heaters, etc.

Static electricity.

Thermal shock (caused by large or abrupt ambient temperature changes –

allow 30 minutes for the Thermometer to stabilize before use).

• Do not leave the Thermometer on or near objects of high temperature.

• Please refer to the emissivity information for the actual temperature. Reective

objects can cause the actual temperature value to be higher than the measured

temperature value. When measuring these objects, please be aware not to touch

high temperature surfaces.

• Replace the batteries as soon as the low battery indicator appears on the display.

• Remove dead batteries from the Thermometer or if it is not going to be used for a

long time.

• Never mix old and new batteries together, or different types of batteries.

• Never dispose of batteries in a re, or attempt to recharge ordinary batteries.

• Before replacing the battery, turn off the Thermometer and disconnect all the test

probes.

• To prolong battery life turn off the Thermometer after use.

OPERATION FUNCTION

Viewing the Last Measured Value

• In the off state, short press the trigger to turn on the thermometer, it will display the

last measurement data that was held before the last shutdown.

Temperature Measurement

• Aim the thermometer at the target, then pull and hold the trigger.

• The laser indicator on the LCD display shows that the laser is turned on and points

to the target.

• The measured temperature value will be displayed on the LCD, and the maximum or

minimum temperature of the target area can be measured by scanning up, down, left

and right according to the laser spot indication.

Hold

• After the trigger is released, the last measured value and the HOLD icon will remain

on the LCD display.

• If there is no operation for 8 seconds, the thermometer will automatically shut down

and save the last measured value.

Unit Conversion

• In the power-on state, open the battery cover and short press the oC/oF button to

switch the temperature unit to Celsius (oC) or Fahrenheit (oF).

Distance to Spot Size Ratio (D:S)

• As the distance (D) from the target being measured increases, the spot size (S) on

the measured area becomes larger.

• The relationship between the distance and the spot diameter is as shown in the

gure below. The spot diameter represents 90% of the energy in the circle.

• The maximum D:S (10:1) will be obtained when the thermometer is 400mm (16”)

from the target resulting in a spot diameter of 40mm (1.6”).

Field of View

• Make sure that the measured target is larger than the spot diameter.

• The smaller the target is, the closer the test distance should be (please refer to D:S

for the spot diameter at different distances).

• To obtain the best measurement result, it is recommended that the target being

measured is 2.5 times larger than the spot diameter.

Emissivity

• Emissivity describes the energy-emitting characteristics of materials. Most organic

materials and painted or oxidized surfaces have an emissivity of about 0.95.

• If possible, to compensate for inaccurate readings that may result from measuring

shiny metal surfaces, cover the surface to be measured with masking tape or at

black paint (<150oC / 302oF) and use the high emissivity setting.

• Allow time for the tape or paint to reach the same temperatures as the surface

beneath it.

• Measure the temperature of the tape or painted surface.

MAINTENANCE

Changing the battery

• To install or change the AAA batteries, open the battery compartment. Replace only

with the same type of battery.

Cleaning the lens

Blow off loose particles using clean compressed air. Carefully wipe the surface with a

moist cotton swab. The swab may be moistened with water.

Cleaning the casing

• Wipe using a damp cloth or sponge. Do not use solvents as these may damage the

casing.

• Do not immerse in water.
