6.7 Speed of response
The speed of response adjustment allows the user to collectively set a number of operating
parameters.
measurement response: is the limit to which the SITRANS LU180 will be able to keep up
with rates of change. If the unit's measurement cannot keep up
with the rate of level change, set the adjustment from '1' to '2'. If it
still cannot keep up with the rate of level change, set the adjust-
ment option to '3'. Avoid choosing an option that is too fast for your
application.
agitator discrimination: discriminates between agitator blades in motion, and the material
(target) surface.
