Note:

1.Resolution
The resolution is the peak-to-peak displacement conversion value of the analog output.
(Conditions: white alumina ceramic at the measurement point)

2.Response Time
The delays are the 10% to 90% rising and falling times of the analog output in response to a sudden change in the displacement.
