Refer to the table below when a problem occurs before consulting your dealer for repair.
Problem
Possible Cause
Remedy
Power does not turn on.
Battery power is insufficient.
Replace the battery (6F22 "006P").
See "Replacing the Battery".
If the power does not turn on
even after replacing the
battery, an element inside the
thermometer may have been
damaged.
If the element inside the unit has
been damaged by impact or drop, the
unit must be repaired.
Contact us or the dealer from which
the product was purchased.
Laser marker does not
operate.
Laser marker is off.
Set the laser marker on.
See "Setting the Laser Marker"
Backlight does not light. Backlight is off.
Set the backlight on.
See "Setting the Backlight".
Temperature reading
is abnormal.
Battery power is insufficient.
Replace the battery (6F22 "006P").
See "Replacing the Battery".
The object is too small or
large for the measurement
spot size
Check the relationship between the
distance and measurement spot size.
See "Measurement Spot Size".
Lens cap is attached on
Check that the lens cap is removed.
Temperature of the object is
fluctuating.
Try measuring the temperature of an
object whose temperature is stable to
check the reading.
Dirt or dust is adhered to the
surface of the infrared lens.
Clean the infrared lens.
See "Maintenance".
Ambient temperature is
fluctuating.
Allow the thermometer to adapt to the
ambient temperature.
See "Notes on Use".
Emissivity of the object is
greatly different from 0.95.
Check the emissivity of the object
with reference to "Measurement of an
object having an emissivity other than
0.95".
If the emissivity is unknown, check it
by applying paint or tape as
described.
There is a high temperature
object near the thermometer
and it is affected by heat.
Shield the heat source with shielding
plates etc.
It is affected by sunlight.
Because the direct sunlight reflects
on the water surface in a sunny day
the correct temperature cannot be
measured
