Operation
optoNCDT 1700
Example:
Measurement range 50 mm, voltage output 0 ... 10 V
Mid-point is set at the position x
m
= 10 mm
Set mid-point results in an output signal of 5 V.
Remaining measurement range respectively
output range:
x
max
= 35 mm
Out
min
= 3 V respectively 8.8 mA
After setting mid-point the sensor gives new
measurement values, related to the mid-point.
The condition before setting mid-point can be
achieved by a reset.
Set mid-point (only error mode): no limit control
The displacement of the characteristic curve re-
duces the usable measurement range of the sensor.
