Shift of the coordinate system during a length measurement
Conditions under which a shift of the coordinate system will influence the measured length:
● You are using an incremental encoder or an initiator or are operating the FM 352 in
simulation mode.
● You are executing a "set reference point" or "retrigger reference point" function while a
length measurement is active.
Example
To utilize the above mentioned influences on the measured length:
Your system always develops slip when you perform a length measurement.
The retrigger reference point function can be used to correct this slip in order to output
correct length measurement values.
