11-2. Abnormal Measured Value
Symptom
Cause/Remedy
(1) Unstable measured value
(1) Check if the measuring terminal is loose.
(2) Check if the input signal is unstable.
(3) Make sure to avoid the following condition: BURN is set to other
than “None” while connecting a thermocouple in parallel with
another instrument.
(2) Measured value display shows
the followings:
OVER, BURN, etc.
(1) Make sure that the wiring to the input terminal is properly done.
(2) Check if the input terminal is loose.
(3) Check if the input line is disconnected.
(4) Check if the input signal is out of the measuring range.
(3) Error occurs in measured value
(1) Check if error occurs in the input signal.
(2) Make sure that a compensation lead wire is connected to the
input terminal (thermocouple input only).
(3) Check the scale and perform input adjustment if error occurs.
(4) Measured value influenced by
ambient temperature
(thermocouple input only)
(1) Check if RJ is set to “EXT” (external) in input type settings (this
is not a problem if reference junction compensation is performed
externally).
(2) Make sure that the terminal cover is attached.
If the troubleshooting does not help solving the problem, immediately contact the dealer or your nearest CHINO
office and give the following information.
(1) MODEL
(2) Serial number
