7. Use the pull-down menu to enable or disable 2-path error
handling. Specific responses of the display and the totalizer are
listed in Table 1-8 below.
2-path error handling
The
two sets of transducers are installed in the same location in the
same pipe to improve accuracy and the meter is operated in
mode. With this function enabled, the Model XGS868 performs
error handling only if both channels are in error. If this function is
disabled, error handling occurs when either channel goes into
error.

Table 1-8: 2-Path Error Response Options
Option Display Response
Displays the average of
Channel1 and Channel2,
No
regardless of the error state
of either channel.
1. If one channel is in error,
the other channel's value
is displayed as the
Yes
average.
2. If both channels are in
error, the last average
reading is held.
After completing the above steps, IDM returns to the

Totalizer Response
Continues to totalize, based on
the last "good" flow reading.
Stops totalizing.
Stops totalizing.
Stops totalizing.
Stops totalizing during critical
errors.
Totalizer Response
Outputs the average of
Channel1 and Channel2
totals, regardless of the error
state of either channel.
1. If one channel is in error,
totalizing continues.
2. If both channels are in
error, totalizing stops.
