Measuring direction
The
Measurement direction
function changes the sign of the relative distance value. The
change of the sign depends on the distance direction from the center of the measuring
range (zero position).
•
Positive
: Distances which are larger than the set zero position of the device are
assigned a plus sign. Smaller distances are assigned a negative sign.
•
Negative
: Distances which are larger than the set zero position of the device are
assigned a minus sign. Smaller distances are assigned a positive sign.

Measured value offset
The measured value offset shifts the zero point of the relative distance value. The
analog output value at this distance is in the middle of the analog value range. With the
help of the measured value offset, distance changes to an individual reference distance
can be measured.
NOTE
When setting the measured value offset, the current gradient of the analog characteris‐
tic curve remains unchanged.
In the main menu, the measured value offset can be set manually.
In the quick menu, the zero point can be taught and reset. The current distance is
taught in as a new zero point (reference point). Menu path information,
.
The distance value that the device outputs and that is evaluated in the switching
functions takes into account the set measured value offset. Only the relative distance
values that indicate the measured value including the measured value offset are trans‐
mitted via the IO-Link communication.
