Non-contact infrared thermometer
Instruction manual
Introduction
Compact, rugged and easy to use. Just aim and push
the button, read current surface te-mperatures in
AS842A
less than a second. Safely me-asure surface
AS852B
temperatures of hot, hazardo-us or hard-to-reach
AS862A
objects without contact.
How it works
Infrared thermometer measure the surface temperature
of an object. The units optical system sense the object s
emitted energy with different wavelength.It is collected
and focus onto a detector. The unit s electronics system
translated the information into a temperature reading
which is displayed on the unit.
Cautions
Infrared thermometer should be protected for the
following:
--EMF (electro-magnetic fields) from arc weld-ers,
induction heaters.
--Thermal shock (cause by large or abrupt ambi-ent
temperature changes allow 30 minutes for unit to
stabilize before use).
--Do not leave the unit on or near objects of high
temperature.
Warning
Do not point laser directly at eye or indire-ctly off
reflective surfaces.

1.When take measurement, point thermome-ter toward
the object to be measured and hold the yellow trigger.
The object under test should be larger than the spot
size cal-culated by the field of view diagram.
2.Distance & spot size: As the distance from the object
increase, the spot size of meas-uring area becomes
larger.
3. Field of view: Make sure the target is larger than the
,
unit's spot size. The smaller the tar-get the closer
measure distance. When acc-uracy is critical, make
,
sure the target is at least twice as large as the spot size.
4. Emissivity: Most organic materials and pa-inted or
oxidized surfaces have an emissiv-ity of 0.95 (pre-
set in the unit). Inaccurate readings will result from
measuring shiny or polished metal surfaces. To
compensate, cover the surface to be measured with
mas-king tape or flat black paint. Measure the tape or
painted surface when the tape or painted reach the
same temperature as the material underneath.
