Configuration Parameters 53
Calculate and set the transducers as follows:
1. To determine the placement of Probe A, add the Cold Set Point to the
Transducer Offset, then add the Axial Position from the Active Face.
2. To determine the placement of Probe B, subtract the Cold Set Point
from the Full Scale Reading, then add the Transducer Offset and the
Axial Position from the Active Face.
3. Enter the following data on the Channels property page in the XM-320
Position Module Configuration Tool.
1 This value is .2 volts below the lowest voltage the transducer will output for this measurement taken from the
calibration chart.
2 This value is .2 volts above the highest voltage the transducer will output for this measurement taken from the
calibration chart.
