CHAPTER 7 CALIBRATION
7.6 Checking Indication Accuracy
· After calibrating input, make sure that you check indication accuracy to
make sure that the E5AK controller has been correctly calibrated.
· Operate the E5AK controller in the PV/SP monitor (level 0 mode) mode.
· Check the indication accuracy at the upper and lower limits and midpoint.

The following figure shows the required device connection. Make sure
that the E5AK controller and cold junction compensator are connected
by a compensating conductor for the input type that is to be used during
actual operation.
