6.6.3 FLOW DISPLAY RANGE
The [FlowDisplay Range] option list offers a choice of [Autorange] (default) or [High Range]. The [Au-
torange] selection increases resolution automatically at low flow rates and reduces resolution at high
flow rates as required to prevent data overflow. If you select [High Range], the meter controls its screen
resolution to prevent data overflow at the highest possible flow.
To edit the Flow Display Range:
To access the [Flow Display Range] option list press the <Right Arrow>.
To move the cursor to the required display range press the <Up/Down Arrows>.
To store selection press <ENTER>.
6.6.4 FLOW DISPLAY SCALE
After you select rate units, the meter automatically computes a prefix to provide the best combination
of capacity and resolution (e.g., KGAL/MIN). The [Flow Display Scale] menu cell shows the results. If
the displayed scaling is not suitable, you can edit it by accessing the option list. Note that this scaling
applies to all flow rate data displayed on the flow display screen, even if the units do not appear next to
the data (because there may not be room on the screen). Therefore, always keep this prefix in mind
when you enter flow related data.
To select a different Flow Display Scale:
To access the [Flow Display Scale] option list press the <Right Arrow>.
Move the cursor to the desired display scale press the <Up/Down Arrows>.
To register selection press <ENTER>.
6.6.5 TOTAL VOLUME UNITS
This menu cell allows you to select which units the meter uses for the flow total output. If you select
mass units, the meter uses the specific gravity parameter (see paragraph 6.3.1) to convert volumetric
flow to mass flow. The default [English Flow Total Units] is [Gallons <US>]. If this suits the application,
press the <Down Arrow> to bypass this menu cell.
To change the default setting:
To access the [Total Volume Units] option list press the <Right Arrow>.
To move the cursor to the desired Total Volume Units press the <Up/Down Arrows>.
To store selection press <ENTER>.
