Display Shift In certain applications it is desirable to shift the con- controlling value or the temperature at the sensor must be trollers indicated value from its actual value. This can be 375 degrees F. Due to the design and position of the easily accomplished with this control by using the dis- components of the system, the sensor could not be play shift function. -
Page 20: Section 6: Calibration Procedure
Section 6: CALIBRATION PROCEDURE Changing these values can make the control useless because it can be put out of calibration. Do not WARNING! attempt to re-calibrate this temperature controller unless you have an adequate calibration instrument available. This must be used to simulate the sensor input. The controller must operate under power for at least 45 3.) Press the scroll button again and the high calibration minutes before starting the calibration procedure. -
