Use the forced-zero shift function to measure the relative values of objects
based on the standard value determined for the Unit. This function requires
ZERO and ZRES (zero reset) inputs to the Unit.
When zero input is turned ON while the Unit is sampling data, the scaled con-
version data will be shifted to zero and stored as binary data in the input word,
