■Safety Precautions

●Do not touch the instrument on an object being tested. A contact with an
object at a high temperature can cause irreparable damage to the instrument
or inaccurate readings.
●Do not touch the measuring window of the instrument with hard objects.
Do not let foreign objects penetrate the measuring window or a hard object
drop on the window.
●Be sure not to use the thermometer when the measuring window has been
broken or cracked, as the user may be injured by shards.
●Always put the cap back on the measuring window after measurement to
prevent foreign objects from penetrating the window.
●In order to protect the optical system of the instrument, do not subject the
instrument to extreme shocks and vibration
●Keep the instrument away from objects with built up static charges.
●Select the proper emissivity value for accurate readings.
●When there is a rapid change to the ambient temperature, wait a while to let
the temperature of instrument stabilize for accurate readings.
●When the instrument is put in storage or not in use for a long period of time,
remove the batteries from the instrument.
●Do not use or store the instrument at a location where;
temperature and/or humidity are high,
the instrument is exposed to the direct sunlight,
there is a lot of dust,
there are greasy fumes or corrosive gasses,
as the measuring window may become deteriorated or soiled, causing
inaccurate readings.
●Do not use the instrument in water or other fluids. Do not store the instrument
where it can come into contact with water.
●Keep the instrument away from objects which produce a strong magnetic field.
■Relation of Distance and
Measuring Diameter
The figure below shows the required minimum area (optical sensitivity: 90%) on an
object under test at a distance of 500mm and 1000mm.
The measured area increases with distance.
When measuring, the distance should be as short as possible.

■Troubleshooting

Symptoms Causes
Batteries have been used up or they have not
No display appears.
been inserted correctly.
Abnormal reading.
Cap is not removed.
Measuring window is dirty.
Measurement was done with maximum or
minimum reading.
Heat source nearby affects the measurement.
Emissivity is not selected properly.
Target area is too small.
Unstable reading Unit is affected by rapid temperature change.
No reading appears
but display is 【---】.
Out of measuring temperature range.
Emissivity selection setting is not matched.
Reading is blinking. Ambient temperature is out of specified range.

■Maintenance

Measuring Window
Dust, stains and flaws on the measuring window cause inaccurate readings.
Wipe stains off with a soft cloth used for lenses of camera. Use absorbent cotton
dipped into neutral detergent diluted with water to remove tough stains.
Other Parts of the Instrument
Clean the instrument with a dry cloth. To remove tough stains, use a damp cloth
from which water-diluted neutral detergent has been rinsed out. Use of paint
thinner, benzine, alcohol and other chemicals may blur the display window, erase
markings or cause the enclosures to crack. It is preferable to keep the instrument
in the carrying case.
Countermeasures
Replace or insert them correctly.
Check if the cap has been removed.
Clean the measuring window, referring to the"Maintenance"
section.
Check the measuring condition. Switch it to current reading.
Shield the heat source with a shielding plate.
If emissivity is unknown, refer to"Reference" section.
Check the target area and keep a sufficient area for measurement.
Leave unit alone to stabilize its temperature, then measure.
Check target to be measured.
Same as above countermeasure.
Check operation environment.
