1.7.6 Rollover of Totals

The totals stored in the ow Btu meter memory will roll over to zero when the maximum

count is exceeded. When this occurs, the network totals will also roll over to zero. The

point at which the rollover occurs is a function of the displayed engineering units and

multipliers programmed into the System-10.

The examples below show the rollover point in the engineering units transmitted by the

network variable (SNVT) for common totals shown on the System-10-LON BTU Meter.
