Automatic Flow Correction
With the function of automatic flow correction, the
flow lost in an offline session can be estimated and
automatically adjusted. The estimate is based on the
average value, which is obtained from flow rate before
going offline and flow measured after going online the
next time, multiplied times the time period that the
meter was offline. Select "ON" to use this function
and "OFF" to cancel this function.
