7. Maintenance and check
7.1 Periodical checking…
Check the followings periodically or if required.
•Lens:
Check the objective lens for dust or dirty.
If dirt is present, remove it with a blower for camera lens. If the dirt cannot be removed with the
blower, wipe the lens gently with cotton ball soaked in alcohol.
•Connections and wirings:
Check all connections and wirings.
7.2 Trouble shooting
7.2.1 Measuring value not displayed or displayed lower
Checking item
Countermeasure
1) Is Er03' lighted' the error display of motor turn
abnormality?
Built-in motor is abnormal. Return to factory to us,
and please order the repair
2) The power voltage is not in the allowable range.
Supply the power with the correct voltage.
3) The Connection cable is not connected firmly.
For the disconnection of the cable, replace it.
4) The view field is interfered.
Make the view field not interfered by referring t o
[4.3 Targeting].
5) The measured temperature is lower than the
minimum value of the measuring range.
It is necessary to use a thermometer with the
measuring
range
covering
the
measured
temperature.
6) The emissivity value programmed is too high.
Program the emissivity value by referring to
[Emissivity programming]. (*)
7) The atmosphere temperature is low, the optic system
is doing no dew .
It uses it in the place where does not do dew.
7.2.2 Measuring value displayed higher
Checking items
Countermeasure
1) The measured temperature is higher than the
maximum value of the measuring range.
It is necessary to use a thermometer with the
measuring
range
covering
the
measured
temperature.
2) The emissivity value programmed is too low.
Program the emissivity value by referring to
[Emissivity programming]. (*)
3) The heat radiation of the high temperature is shining
to the measurement face or thermometer from the
outside.
Heat is prevented with the board that does not pass
the change or light of the place
7.2.3 Display fluctuated
Checking items
Countermeasure
1) The radiation thermometer is not fixed firmly or
vibrated.
Fix the radiation thermometer firmly and install it
in a place not vibrated.
2) The connector and terminal are not connected
firmly.
Connect the connector and terminal firmly.
3) The power voltage is not in the allowable rang
Supply the power with the correct voltage.
4) The view field is interfered by steam.
Purge the steam by air.
5) The measured temperature is fluctuated exactly.
Program the emissivity value and the modulation
degree by referring to the following paragraphs.
[Emissivity
programming](*)
[Automatic
emissivity calculation] (*)[Signal modulation mode
selection] (*)[Modulation degree programming] (*)
6) Emissivity value is changeabling.
(*): Refer to separate instruction manual [IR-CA series Software volume].
1. Do not disassemble this thermometer. If you disassemble, it causes the obstacle to
your eye because laser function is built-in.
2. Make sure to target the laser when you want to decide the center of the measuring
object only and to keep on following the above procedure when you exactly target the
laser. Any adjustment or procedure other than specified here makes you expose in
dangerous laser radiation.
