After calibrating input, make sure that you check indication accuracy to
make sure that the E5CK controller has been correctly calibrated.
Operate the E5CK controller in the PV/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 E5CK controller and cold junction compensator are connected
by a compensating conductor for the input type that is to be used during
actual operation.
