8. Note:
8.1 Do not use solvent to clean lens.
8.2 Do not submerge the unit in water.
8.3 Do not use/place the unit in high temperature or moist
environment, that might inflect the units performance.

1.Introduction
Compact, rugged and easy to use. Just aim and push
the button, read current surface temperature in less than
a second. Safely measure surface temperature of hot,
hazardous or hard-to-reach objects without contact.
2.How it works
Infrared thermometer measures the surface temper ature of an object. The unit's optics sense emitted, ref lected, and transmitted energy which is collect and fo cused onto a detector. The unit's electronics translate
the information into a temperature reading which is dis played on the unit.
For increased ease and accuracy the laser pointer
makes aiming even more precise.

Check the data store off-line record curve graph.
6.3 DC : For saving battery consumption, please
use 9V 500mA adapter on long period measurement.

7.1 Lens cleaning: Blow off lose particles using clean
compressed air. Gently brush remaining debris away
with a moist cotton cloth.

7.2 Case cleaning: Clean the case with a damp sponge
cloth and mild soap.

3.2Warning
-- Do not point laser directly at eye or indirectly off reflective
surfaces.
-- The unit cannot measure through transparent surfaces
such as glass or plastic. It will measure the surface
temperature of these materials instead.
-- Steam, dust, smoke, or other particles can prevent
accurate measurement by obstructing by the units optics.
4.1 When take measurement, point thermometer toward
the object to be measured and hold the yellow trigger.
The object under test should be larger than the spot size
calculated by the field of view diagram.
4.2 Distance & spot size: As the distance from the object
increase, the spot size of measuring area becomes larger.
4 Operation Instructions
3.Cautions
3.1Infrared 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 30 minutes for unit to stabilize
before use).
--Do not leave the unit on or near objects of high temperature.
--Static electricity.

4.3 Field of view: Make sure the target is larger than the
unit's spot size. The smaller target the closer measure
distance. When accuracy is critical, make sure the target is
at least twice as large as the spot size.
4.4 Emissivity: Most organic materials and painted or
oxidized surfaces have an emissivity of 0.95 (pre-set in
the unit). Inaccurate readings will result from measuring
shiny or polished metal surfaces. To compensate for this,
adjust the units emissivity reading (see table below and
5.3 settings) or 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.
