2.2 BAC OBJECTS
The System-10 BTU Meter operates in one of three operating modes: single, dual or bi-
directional. The table below contains point information for each of the operating modes.
In single mode operation, only one register accumulates energy and one register accumulates
volume. Thus, only two AV points and two BV reset points are necessary.
