The effective stroke length is specified either in the 32-bit
integer or decimal format (depending on the bit UNIT) in
the output data byte 0 ... 3. For the length to be accepted,
the bits PARAM0 and PARAM1 must equal 0.
The value is accepted with the bit LOAD_P = 1.
Confirmation takes place through the bit ACK = 1 in the
status byte SCON.
3. A zero point can be defined with the bit REF = 1.
Confirmation takes place through the bit ACK = 1.
REF_OK is already previously = 0.
Negative values are output below the zero point, positive
values above it.
If a zero point is established, it remains stored even after
switching on or off.
Generally: Play within the measurement application has a
negative effect on the achievable accuracy.
Tip: You can also perform all one-time settings with the
CPX-FMT. Fig. 3/4 shows the effective stroke length
being written as an example.
