Damping
Analog output response to a step change is user-selectable from 0 to 60 seconds for one time
constant. Each variable can be individually adjusted. This software damping is in addition to
sensor module response time.

alert the user. Rosemount standard (default), NAMUR, and custom alarm levels are available
(see Tab le A -1 below).
High or low alarm signal is software-selectable or hardware-selectable via the optional switch
(option D1).
