Page 7: Control Parameters
Digital Temperature Controllers MR301/302 7.1. Control parameters Parameter: This parameter defines proportional band for PID control output. In this band around the Set Point, the control output (Control Value) is proportional to the error signal (the difference between the Process Variable and the Set Point). Outside this range the output is on or off (depending on the control action and error signal). - Page 8 Digital Temperature Controllers MR301/302 Figure 6 Parameter: The parameter determines intensity of input signal digital filtering. For tAU=0 there is no filtering. For tAU=5 filter time constant is approx. 8 seconds. Each decrement by 1 halves time constant. Suggested value is 2.

Page 9: Calibration Parameters
Digital Temperature Controllers MR301/302 Parameter: The value of OFS is added algebraically to the measured value. Possible reasons are: Removal of input sensor zero error Compensation of thermal gradient - temperature difference between the sensor location and the point of desired temperature measurement... -
Page 10: Device Calibration
Digital Temperature Controllers MR301/302 9. Device calibration There are 5 calibration parameters to calibrate measuring. Parameters tr0 and tr1 are to calibrate Pt100 measuring, while the parameters tv0, tv1 and CJC calibrate thermocouple measurement. For calibration do the next steps: Power up the device and leave it 15 minutes to warm up. -
