Calibration
Notes
1. Disconnect load power when calibrating.
2. RTD inputs should be calibrated using
copper (Cu) wire, and thermocouple inputs
should be calibrated using thermocouple
extension wire of the same type as the ther-
mocouple you are calibrating.
3. Substitute a precision sensor simulator
(thermocouple simulator or resistance de-
cade box) for the sensor inputs. The control-
ler should be allowed to warm-up with the
appropriate sensor simulator connected for
at least one hour prior to calibration.
4. To access the calibration, you will need to
be at LEVEL D security. Enter Security Code
“736” at menu LOCH on the SET PAGE.
