Use this menu cell to
select meter response
to a fault condition.
Fault drops outputs to
zero. Memory retains
last valid reading for
duration of Memory
Delay.
Use this menu cell to enter
the duration (in sec.) that you
want the meter to maintain its
last reading for during a fault
condition. The hidden cell only
appears if you select Memory
Mode.
Use this menu cell to
enter a flow rate

Flow rates below this
level will be reported
as zero flow.

6.5 THE OPERATION ADJUST MENU
This menu becomes available after picking a meter type and measurement channel. We recommend
that you use it after the transducers are installed and operating to “fine-tune” the meter’s output char-
acteristics.
Each application presents different data display and output requirements due to unique pipe and liquid
conditions. Use the [Operation Adjust] menu to match meter operation to the site. You can set damping
controls for the primary flow rate output. You can define a Deadband (i.e., usually a very low flow rate)
below which the flow output will be forced to zero. You can also select the meter response to a continu-
ous Fault condition.
