7.4.2.2 Deadband
Deadband is a zone of flexibility around the threshold. The alarm does not go abnormal until the
temperature exceeds the threshold value by the number of set deadband degrees. Thereafter, it does not
go normal until the temperature is below the threshold by the number of set deadband degrees. The
deadband is factory preset to ±2 K of threshold value. Adjusting to other values is accomplished through
DataTemp Multidrop Software. For information on the sensor’s communication protocols, see section
10 Programming Guide, page 67.
