Caution

Waterproof
Hand-held Infrared
Thermometer

IRT-500-TE is one of the portablelaser applied instruments which
are regulated by the consumer
product safety law.
• Do not stare into the laser beam.
• Do not aim the laser beam atpeople.
• Keep the instrument out of
the reach of children.

Relation of Distanceand Measuring Diameter
The relation between the distance and measuring diameter is asfollows.
The more the distance increases, the required area becomes large.
For an accurate reading, a sufficient measuring area should beensured.
(Unit: mm)

Maintenance
Measuring Window
The measuring window applies a waterproof structure (IP67). If
water-soluble stains adhere to the window, wash the measuringwindow with the tap water. Dry the measuring window well after
washing. Please note that measurement while the measuringwindow 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.

Do not use chemical agents such as thinner, benzine or alcohol
since these may cause a crack or fog on the surface of themeasuring window, and consequently it may change the infrared
radiation transmittance of the plastic lens.

•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 themeasuring 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 ameasured 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 theinstrument in a location
where it is exposed todirectsunlight,
dust,
lampblack and corrosive
gas, or where temperature
and/or humidity is high.
Otherwise the measuringwindow will become soiled ordeteriorated,whichcancause inaccurate readings.

As this instrument has a waterproof structure (IP67), a slightamount of water will not damage the instrument. When theplastic 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.

The above measuring diameter is defined as an area which allows
the capture of more than 90% of energy.

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 thestains, put the top hood back to the previous place by aligning theslots and projections along the edge of the hood and on the device
together. After this, ensure that the hood is fastened and will notcome apart.

Symptoms

Cause

Countermeasures

No display appears

Batteries have been exhausted or they are not placedcorrectly.

Replace or place them correctly.

Laser beam is not emitted or isweak.

Battery voltage is low.

Measurement is possible. Replace batteries when the laser marker isnecessary.

Abnormal reading

Plastic lens is dirty.

Clean the plastic lens referring to the “Maintenance” section.

A heat source nearby is affecting measurement.

Shield the heat source by a shielding plate.

Emissivity is not selected properly.

If emissivity is unknown, refer to “Reference” section. Also, measure thetemperature by a contact type thermometer and select adequate emissivityso that temperature of this instrument becomes equivalent to that of thecontact type thermometer.

The measuring target area is too small.

Check the target area and keep a sufficient area for measurement.

Unstable reading

The unit is affected by a rapid temperature change.

Leave the unit to stabilize its temperature, then measure.

No reading appears but display is‘OL.’

Out of measuring temperature range

Check the target to be measured.

Usage and Part Names

BatteryMeasurement Display(1) Installing Batteries
Loose the screw at the lower part of thebattery cover, pressing the battery
compartment cover as shown and removing
it. Install batteries positioning the negativeand positive poles properly as shown inside
the compartment. Then fasten the screw
and put the cover back.

Aim the measuring window at the measuring target, and press theMEASURE key. Holding down the MEASURE key, confirm if thelaser beam irradiates the measuring position properly. Adjust theposition, if the laser beam does not irradiate the measuring position
properly. Measuring continues while the MEASURE key is being
held down. When the MEASURE key is released, the measured
value is held for about 30 seconds, and then the power is shut off
with the Auto Power Off function.
If the measuring window is aimed at a new target and theMEASURE key is pressed while the measured value is being held,
the temperature of the new target will be measured. When theMEASURE key is released, the newly measured temperature will beheld.

Battery CoverNote:
If the battery cover is not screwed in tightly, the waterproof property will be
deteriorated, and performance may be deteriorated due to water penetration inthe unit.
However, do not fasten the screw too tightly when replacing the battery cover.

Note:
When replacing batteries, replace both batteries at the same time.

Settings
Normally only the object emissivity is selectable. The emissivity is set at0.95 at the factory. The emissivity is displayed during measurement(except for emissivity 0.95. When nothing appears on the display, itmeans that the emissivity is 0.95.) Five variations of emissivity ranging
from 0.8 to 1.0 can be set at every 0.05 step.
The emissivity can be altered by setting the 3 digits (2nd, 3rd and 4thdigits from left) of the 4-digit slide switch in the lower part of the battery
compartment. The setting mode of the slide switch is displayed below thebattery part. Remove the batteries, and set as required according to thedisplayed setting mode.
If necessary, the measurement unit can be switched to Fahrenheit ( )(with the leftmost digit of the 4-digit slide switch.)
