Initial Parameter Setups and Save
Load and save the parameters. 18 different sets of
setup conditions/groups are available to load and save
by three methods:

Cross-Sectional Area
Display the cross-sectional area inside the pipe.
Holding With Poor Sig
Select "Yes" to hold last good flow signal displayed if
the flowmeter experiences a poor temporary signal
condition. This function will allow continued data
calculation without interruption.
Empty Pipe Setup
This parameter is used to overcome the possible
problems that usually show up when the pipe being
measured is empty. Since signals can be transmitted
through the pipe wall, the flow meter may still read a
flow while measuring an empty pipe. To prevent this
from happening, you can specify a value. When the
signal quality falls below this value, the measurement
stops automatically. If the flow meter is already able
to stop measuring when the pipe is empty, a value in
the range of 30 to 40 should also be entered in this
