Non-contact infrared thermometer

Introduction
Compact, rugged and easy to use. Just aim and push the
button, read current surface temperatures in less than a
second. Safely measure surface temperatures of hot,
hazardous or hard-to-reach objects without contact.
How it works
Infrared thermometer measures the surface temperature
of an object. The unit’s optics sense emitted, reflected,
and transmitted energy which is collect and focused onto
a detector. The unit’s electronics transmitted energy
which is display on the unit. For increased ease and
accuracy the laser pointer makes aiming even more
precise.
Cautions
Infrared thermometer should be protected for the
following:
--EMF(electro-magnetic fields) from arc welders,
induction heaters.
--Thermal shock(cause by large or abrupt ambient
temperature changes allow 1 hours for unit to stabilize
before use).
--Do not leave the unit on or near objects of high
temperature.
Warning
Do not point laser at eye or indirectly off reflective
surfaces.
1. When take measurement, point thermometer toward
the object to be measured and hold the yellow
trigger. The object under test should be large than
the spot size calculated by the field of view
diagram.
2. Distance ＆spot size: As the distance from the
object increase, the spot size of measuring area
becomes large.
3. Field of view: Make sure the target is larger than the
unit’s spot size. The smaller the target the close
measure distance. When accuracy is critical, make
sure the target is at least twice as large as the spot
size.
4. Emissivity: Most organic materials and painted or
oxidized surfaces have an emissivity of 0.95.
Inaccurate readings will result from measuring
shiny or polished metal surfaces. To compensate,
cover the surface to be measured with masking tape
or flat black paint. Measure the tape or painted
surface when the tape or painted reach the same
temperature as the material underneath.

Quick start instruction
1. Press battery door clip, install battery correctly. Pull
the trigger, LCD display reading ＆battery icon.
Release the trigger and the reading will hold for 7
seconds
LCD display:
A Laser pointer turn on prompt
B Alarm of high temperature prompt
C Alarm of Low temperature prompt
D Data Hold
E Measure result
F Emissivity

2. Locating a hot spot aim the thermometer outside the
area of interest, then scan across with up and down
motions until you locate the hot spot.(please turn on
the laser to for accurate measuring)
3. Diagram description
(1) Trigger ：Press for turn on, and then display test
result and hold data 7 seconds automatically ("HOLD")
after unclamping switch. Trun off automatically after 10
seconds without operate.
(2) Laser pointer button ：press it for turn on laser
pointer, press again for turn off.
(3) Back light /Up button ：In “Alarm temperature” and
“setting emissivity” mode for adjust value up. In
other mode for turn on back light.When product
working, press it for turn on back light, press again
for turn off.
(4) MODE button：Press MODE button for cycle
options - MAX -AVG - MIN –HAL –LAL mode
A、MAX：Measure maximum data current；
B、MIN：Measure minimum data current；；
C、AVG：Calculate the average of all measure data；
D、HAL：Alarm of high temperature. Option HAL
mode, press “UP/DN ”button for set alarm
temperature. When LCD display ”H” means
measure result exceeded the alarm temperature；
E、LAL：Alarm of low temperature. Option HAL
mode, press “UP/DN ”button for set alarm
temperature. When LCD display ”L” means
measure result under the alarm temperature；
(5) T/ DN button ：In “Alarm temperature” and “setting
emissivity” mode for adjust value down . When turn
on product and press direct for ℃/ 0F select.
(6) SET button：Press for setting emissivity . And press
“UP/DN” for adjust from 0.1~1.0. Press SET button
again for exit setting mode .

Maintenance
1) Lens cleaning: Blow off lose particles using clean
compressed air. Gently brush remaining debris away
with a moist cotton cloth.
2) Case cleaning: Clean the case with a damp
sponge/cloth and mild soap.
3) Please take out the battery when not using for a long
time.
Note:
1) Do not use solvent to clean lens.
2) Do not submerge the unit in water.
