Non contact infrared thermometer

User manual
1、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.
5. When changing from low temperature environment to high
temperature environment or from high temperature
environment to low temperature environment, please wait for
30 minutes, and then measure after the temperature of the
machine is balanced with the ambient temperature.
2、Quick start instruction
1. Remove the battery cover screw with a screwdriver, and then slide
out the battery door, install battery correctly. And Put back to the
battery door screws .Pull the trigger, LCD display reading ＆
battery icon. Release the trigger and the reading will hold for 10
seconds.

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)
