CAUTION - Laser Light   
Do not aim laser beam toward faces.   
Do not stare into beam or into reflections of the beam 
off mirror-like surfaces.   
Do not attempt to open the housing, other                                               
than to change the batteries. There are no other 
user-serviceable parts inside.   

 

■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. 

 
●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 being tested at a distance of 500mm and 1000mm. 

The measured area increases with distance.   

When measuring, the distance should be as short as possible.

■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. 

 

  Note   

Use of other substance other than neutral detergent can damage the window to 

cause the laser beam to scatter. 

 

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.

Symptoms

Causes

Countermeasures

No display appears.

Batteries have been used up or they have not
been inserted correctly.

Replace or insert them correctly.

Laser beam is not
emitted or is weak.

Battery voltage is low.

Measurement is possible. Replace batteries when the laser maker is
necessary.

Cap is not removed.

Check if the cap has been removed.

Measuring window is dirty.

Clean the measuring window, referring to the“Maintenance” section.

Measurement was done with maximum or
minimum reading.

Check the measuring condition. Switch it to current reading.

Heat source nearby affects the measurement.

Shield the heat source with a shielding plate.

Emissivity is not selected properly.

If emissivity is unknown, refer to“Reference”. Or measure temperature
with a contact type thermometer and obtain adequate emissivity by
changing it to have same temperature as measured on condition of
emissivity selection at FREE.

Target area is too small.

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

Unstable reading

Unit is affected by rapid temperature change.

Leave unit alone to stabilize its temperature, then measure.

Out of measuring temperature range.

Check the target to be measured.

Emissivity selection setting is not matched.

Same as above countermeasure.

Reading is blinking.

Ambient temperature is out of specified range.

Check operation environment.

Abnormal reading.

No reading appears
but display is 【---】.
