Emissivity rate (ε)

The emissivity rate is the rate of energy emitted from the surface of an object. Every object has
a unique emissivity rate which is variable according to the surface condition and temperature
of the object. This product allows for setting a desired emissivity rate, which can enable even
more precise measurement by adjusting the emissivity rate according to that of the target.
An object with low emissivity rate (e.g. a shiny metallic object) refl ects the surrounding
temperature since it is highly refl ective. If the surrounding objects have greatly different
temperature from that of the main unit, their temperatures are refl ected resulting in incorrect
measurement. Therefore it is necessary to block out such effect.
The maximum emissivity rate is normally 1.00, but this unit is designed to accept up to 1.20 for
practical convenience.

(1) Press the ENTER button in the Teach mode after confi rming the target

is aimed suffi ciently larger than the fi eld of view.

(2) When the current measurement value is displayed, input the

temperature of the target.
(3) Press the ENTER button to confi rm the setting.
(4) Check that the indicated value and emissivity rate have been changed.

(1) In the ε mode, press the ENTER button to make the

setting.
(2) Directly input the emissivity rate.

Combination of alarm output and trigger input

Setup of Functions

This unit allows individual setting for each function.
The behavior when the alarm output and trigger input are combined is as described below.
The alarm output uses the analog output value as the judgment criterion, so when the trigger
input is set, the controlled analog output will be the judgment criterion.

Problem Cause Action

Cannot measure.

The power is not applied. Check the cabling and connections.

The power voltage is low.

Check the power voltage and adjust it to
the 12 to 24 VDC range.

The
measurement
value is wrong.

The lens is dirty.

Clean the lens referring to the Lens section
under “Maintenance”.

The measurement area is off center.

Adjust the mounting position so that the
target comes to the center of the area.

A high-temperature object is near the
target affecting the measurement.

Block the heat source using a board, etc.

The emissivity rate setting is not
correct.

Set the emissivity rate to that of the target.

The measurement
value is not
stable.

The sensor head is affected by
vibration.

Prevent vibration.

The sensor head is affected by rapid
temperature change.

Leave the sensor head for a while until the
temperature becomes stable.

Troubleshooting

Maintenance

Lens Dust, dirt and scratches on the lens can cause incorrect measurement. If the lens is dirty,

remove the dust using a blower for cleaning lens. For stubborn dirt, apply a small amount
of ethyl alcohol to a cotton swab or special lens cleaning cloth and gently wipe off the dirt.

Amplifi er For heavy dirt on the amplifi er, use a lightly moistened cloth to wipe it off. Do not use

alcohol or such other material because it may damage the surface or fade the printing.

Calibration Yearly calibration is recommended. The sensor head and amplifi er cannot be separately

calibrated. Always calibrate them together. For details, contact the sales distributor.

* If the problem persists even after taking the actions above or the problem is not listed here, contact

the sales distributor

.

You can rinse the sensor head with water because it is water-resistant. However, water drops remaining
on the lens will cause incorrect measurement. Be sure to wipe them off with a soft cloth or blow them off
with air.
You can easily remove water or oil by using air as the water/oil-repellent coat is applied on the surface
of lens.
If the unit may be exposed to splash of water or oil or located in a dusty place during measurement, use
the optional air purge collar.
