Setting the “taring” digital input begins the recalculation of the offset. This is described
in Section 3.3 Taring (zero setting). The “taring active” digital output is set until the
procedure is completed or aborted. If the “taring” input is reset before the remaining
time has elapsed, the procedure is aborted, the “taring active” digital output is reset,
and the offset value is not changed.
