There are two operating modes for the totalizer:
Standard totalizer and difference totalizer.

pulses for the forward and reverse flow directions are counted
independently on two totalizers. When the flow direction is
forward, only the forward totalizer integrates the flow. The
selection is made with the STEP and DATA keys and accepted

In the difference totalizer mode a single totalizer is utilized for
both flow directions. The flow in the forward flow direction is
added and the flow in the reverse direction subtracted. The
pulse output is not affected by this selection.
