Checking Indication Accuracy
Section 6-7
6-7 Checking Indication Accuracy
• After calibrating the input, be sure to check the indication accuracy to
make sure that the calibration has been executed correctly.
• Operate the E5CN/CN-U/AN/EN in the process value/set point monitor
mode.
• Check the indication accuracy at the following three values: upper limit,
lower limit, and mid-point.
6-7-1 Thermocouple or Infrared Temperature Sensor
•Preparations
The diagram below shows the required device connections. Make sure
that the E5CN/CN-U/AN/EN and cold junction compensator are con-
nected by a compensating conductor for the thermocouple that is to be
used during actual operation.
• Operation
Make sure that the cold junction compensator is at 0
°C, and set the STV
output to the voltage equivalent of the starting power of the check value.
The cold junction compensator and compensation conductor are not
required when an external cold junction compensation method is used.
