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 E5
@
C in the process value/set point monitor mode.
• Check the indication accuracy at the following three values: upper limit, lower limit, and mid-point.
• To check the range of an infrared sensor, set the input type parameter to 6 (i.e., a K thermocouple)
and input a voltage that is equivalent to the starting power of a K thermocouple.

• Preparations
The diagram below shows the required device connections. Make sure that the E5
@
C and cold
junction compensator are connected 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.
