• After calibrating input, be sure to check indication accuracy to make
sure that the E5GN has been correctly calibrated.
• Operate the E5GN in the PV/SP monitor mode.
• Check the indication accuracy at the upper and lower limits and mid
point.
• Preparation
The following figure shows the required device connection. Make sure
that the E5GN and cold junction compensator are connected by a com
pensating conductor for the thermocouple that is to be used during
actual operation. For the non contact temperature sensor, connect a K
thermocouple, and set the input type to the K thermocouple.

• Operation
Make sure that the cold junction compensator is at 0_C, and set STV out
put to the voltage equivalent to the starting power of the check value.
The cold junction compensator and compensation conductor are not re
quired when an external cold junction compensation method is used.
• Preparation
The following figure shows the required device connection:
