2. Locating a hot spot: To find a hot spot aim the
thermometer outside the area of interest, then
scan across with up and down motions unitl you
locate the hot spot.(please turn on the laserto for
accurate measuring)

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.

a. MAX: measuring maximum temperature
b. MIN: measuring minimum temperature
c. DIF: Basic on the reading before press 4 key,
compute the difference of current reading.
d. AVG: measuring average temperature
e. HAL: high temperature alarm--when selected
HAL, press 5 keys to set high temperature alarm
trigger and confirmed by pressing 4 key. When
reading over trigger, LCD display HI icon with
BiBi audio sounds.
f. LAL: low temperature alarm--when selected
LAL, press 5 keys to set low temperature alarm
trigger and confirmed by pressing 4 key. When
reading over trigger, LCD display LOW icon with
BiBi audio sounds

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.

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.
Note:
1) Do not use solvent to clean lens.
2) Do not submerge the unit in water.
