Caution
IRT-500-TE is one of the portable
laser applied instruments which
are regulated by the consumer
product safety law.
• Do not stare into the laser beam.
• Do not aim the laser beam at
people.
• Keep the instrument out of
the reach of children.
Please follow the precautions below for use to keep
the instrument's functions proper and to enable
accurate measurement.

Safety Precautions

•
Do not allow this product to come into contact with the object
being measured.
This is a contactless thermometer. Contact with a hot section
may cause irreparable damages or inaccurate readings.
•
Do not damage the measuring window (plastic lens).
Do not allow a hard object to come into contact with the
measuring window.
Do not let a foreign object penetrate the measuring window,
or drop a hard object on the measuring window.
•
Although this instrument applies a shockproof structure, do
not allow the instrument to be exposed to excessive shocks.
•
Do not bring the instrument close to an electrostatic object.
•
Emissivity of this instrument can be selected (0.8 to 1.0).
When the emissivity setting is different from that of a
measured object, an inaccurate reading will occur.
•
Sudden changes in ambient temperature will cause
inaccurate readings. Wait a while to let the temperature of the
instrument stabilize, and then measure it.
•
Remove batteries from the instrument if the instrument is not
in use for a long period or is put in storage.

Environmental Precautions

•
Do not use or store the
instrument in a location
where it is exposed to
direct sunlight, dust,
lampblack and corrosive
gas, or where temperature
and/or humidity is high.
Otherwise the measuring
window will become soiled or
deteriorated, which can
cause inaccurate readings.
•
As this instrument has a waterproof structure (IP67), a slight
amount of water will not damage the instrument. When the
plastic lens is wet, however, wipe the lens carefully so as not
to scratch it as being wet will cause inaccurate readings.
•
Keep the instrument away from an object which radiates
strong electromagnetic waves.
Relation of Distance
and Measuring Diameter
The relation between the distance and measuring diameter is as
follows.
The more the distance increases, the required area becomes large.
For an accurate reading, a sufficient measuring area should be
ensured.
(Unit: mm)
The above measuring diameter is defined as an area which allows
the capture of more than 90% of energy.

Troubleshooting

Symptoms Cause
No display appears Batteries have been exhausted or they are not placed
correctly.
Laser beam is not emitted or is Battery voltage is low.
weak.
Abnormal reading Plastic lens is dirty.
A heat source nearby is affecting measurement.
Emissivity is not selected properly.
The measuring target area is too small.
Unstable reading The unit is affected by a rapid temperature change.
No reading appears but display is Out of measuring temperature range
'OL.'

Maintenance

Measuring Window
The measuring window applies a waterproof structure (IP67). If
water-soluble stains adhere to the window, wash the measuring
window with the tap water. Dry the measuring window well after
washing. Please note that measurement while the measuring
window is wet will cause inaccurate readings. If oil-soluble stains
adhere to the measuring window, wipe it with a cloth dipped in the
diluted neutral detergent and rinse it.
Note
Do not use chemical agents such as thinner, benzine or alcohol
since these may cause a crack or fog on the surface of the
measuring window, and consequently it may change the infrared
radiation transmittance of the plastic lens.
Plastic Lens
Dust, stains and scratches on the measuring window cause
inaccurate readings. Wipe such stains off with a soft cloth or cotton
bud for camera or glasses. To get rid of tough stains, remove the top
hood (rubber) by drawing it, and wipe the lens with a cloth dipped in
the diluted neutral detergent and rinse it. After getting rid of the
stains, put the top hood back to the previous place by aligning the
slots and projections along the edge of the hood and on the device
together. After this, ensure that the hood is fastened and will not
come apart.
Hood
Countermeasures
Replace or place them correctly.
Measurement is possible. Replace batteries when the laser marker is
necessary.
Clean the plastic lens referring to the "Maintenance" section.
Shield the heat source by a shielding plate.
If emissivity is unknown, refer to "Reference" section. Also, measure the
temperature by a contact type thermometer and select adequate emissivity
so that temperature of this instrument becomes equivalent to that of the
contact type thermometer.
Check the target area and keep a sufficient area for measurement.
Leave the unit to stabilize its temperature, then measure.
Check the target to be measured.
