• After calibrating input, be sure to check indication accuracy to make
sure that the E5EK-T controller has been correctly calibrated.
• Operate the E5EK-T controller in the PV/Present SP monitor (level 0
mode) 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 E5EK-T controller and cold junction compensator are con-
nected by a compensating conductor for the input type (thermocou-
ple) that is to be used during actual operation.

• Operation
Make sure that the cold junction compensator is at 0_C, and set STV
output to the voltage equivalent to the starting power of the check
value.
