HoldPeak HP2150 Instruction Manual

Non-contact infrared thermometer
Instruction manual
MODEL : 200 ℃ TO 2150 ℃（ 392 TO 3902
1.Introduction:
Compact,rugged and easy to use.Just aim and push the
button,read current surface temperatrue in less than a
second.Safely measuere sur face temperature of
hot,hazardous or hard-to-reach objects without contact.
2.How it works:
Infrared thermometer m easures 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 translate the information
into a temperature reading which is displayed on the unit.
For increased ease and accuracy the laser pointer makes
aiming even more precise.

3.Cautions:
Infrared thermometer should be protected for the following:
-EMF(electro-magnetic fields) from arc welders,induction-
heaters.
-Thermal shock(carse by large or abrupt ambient temper ture
changes allow 30 minutes for unit to stabilize before use )
-Do not leave the unit on or near objects of high temperture.
-Static electricity.
4.Warning:
-Do not point laser directly at eye or indirectly off dflective
surfaces.
-The unit cannot measure through transparent sur faces such
as glass or plastic.It will measure the sur face temperature of
these materials instead.
-Steam ,dust ,smoke,or other par ticles can prevent accurate

measurement by obstructing by the units optics.
5.Operation
-When take measurement ,point thermometer toward the
object to be m easured and hold the yellow trigger.The object
under test should be larger than the spot size calculated by the
field of view diagram.
-Distance & spot size:As the distance from the object
increase,the spot size of measuring area becomes larger.
-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
9 V
DC IN
least twice as large as large as the spot size.

-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 sur faces.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.
