Calibration
Notes
1. Disconnect load power when calibrating or
disable the control output using the
pushbutton.
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 thermocouple you are
calibrating.
3. Substitute a precision sensor simulator
(thermocouple simulator or resistance decade
box) for the sensor inputs. The controller 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 CTRL PAGE.
