Differential measurement mode
Simultaneous connection to SPC control or a PC via the RS 485 interface is not possible with
differential measurement.
With this measuring procedure, two devices are connected to one another. The measuring ranges can overlap (1), be
directly adjacent (2) or apart (3) (Illustr. 18).
To achieve optimum use of the measuring range, the measuring object should if possible be aligned in the centre of
the measuring range.
3. One of the sensors must be configured as a slave. Activate function 26 (see “Settings”, page 32)
