4.4.1 Continuous Operation Mode
The sensor makes the acceleration value available as analog output variable either as current or voltage
value on separate pins, depending on the configuration using the software tool of Micro-Epsilon.
In this process, the symmetrical measurement range in the unit g is scaled to the respective analog range.
The sensitivity increases with decreasing measurement range as only a small acceleration range is scaled to
the same output range
