7.6 Checking Indication Accuracy
• After calibrating input, make sure that you check indication accuracy
to make sure that the E5EK controller has been correctly calibrated.
• Operate the E5EK 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 E5EK controller and cold junction compensator are con -
nected by a compensating conductor for the input type that is to be
used during actual operation.
