10. Maintenance and check
10.1 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 wiring
10.2 Trouble shooting
At time when a trouble was accepted, please give appropriate treatment in checking the following.
10.2.1 Measuring value not displayed or displayed lower
Checking item
Countermeasure
1) The power voltage is not in the allowable
range.
Supply the power with the correct voltage.
2) The Connection cable is not connected
firmly.
For the disconnection of the cable, replace it.
3) The view field is interfered.
Make the view field not interfered by referring to
[7.Targeting].
4) 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.
5) The emissivity value programmed is too
high.
Program the emissivity value by referring to
[Emissivity programming]. (*)
6) The atmosphere temperature is low, the optic
system is doing no dew .
It uses it in the place where does not do dew.
10.2.2 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.
10.2.3 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 changed.
(*) : Refer to separate instruction manual [IR-CZQH Series software volume.]
Do not disassemble this thermometer.
