Case 2 Temperature Change Greater than the
Threshold Value2% of Output Range
Case 3 Temperature Change Within the Threshold Value 2 % of Range
Intermittent Sensor Algorithm and Damping
2.0 seconds, the transmitter outputs the reading that corresponds to
Intermittent Sensor Detect Advanced Feature
the damping curve at that time , and continues to calculate and
continues to approach the input curveaccordingto theequation above
