3.4.3.4.6 Damping value
Description
Sets the Damping (filtering) to smooth out response to sudden changes in measurement.
An increase to Damping value increases response time of device, and affects digital value
and loop current. If output values are noisy, increase Damping value. For faster response
time, decrease Damping value. Find a value that meets requirements of signal stability and
response time.
Setting 0.00 s to 100.00 s
Default 0.00 s
