Damping
4-20 mA HART
2051 with Selectable HART
Analog output response to a step input change is user-enterable from 0.0 to 60 seconds for one
time constant. This software damping is in addition to sensor module response time.
2051
Analog output response to a step input change is user-selectable from 0 to 36 seconds for one
time constant. This software damping is in addition to sensor module response time.
