THE FLOW/TOTAL UNITS MENU

The [Flow/Total Units] menu is available after selecting a flowmeter type and measurement channel.
Use the [Flow/Total Units] menu to select mass and volumetric flow units and an associated time base.
Independent volume/mass units can be selected by the Totalizer. After making your selections, a view-
only menu cell shows the resultant scaling. Another menu cell lets you adjust the output resolution by
selecting a display range.
This system provides three totalizer display modes:
POSFLOW ............................. Positive (forward) flow total only
NEGFLOW ............................ Negative (reverse) flow total only
NETFLOW ............................. The net of the Positive and Negative flow (default)
The flow computer stores positive and negative accumulations in separate independent registers. It
develops the NETFLOW output by summing the positive and negative totalizer registers. You use the
keypad's function and numeric keys to control the flow totalizer registers.
Use this menu cell to select
either volumetric or mass flow
rate units .
Use this menu cell to select a
time base for the flow rate
units.
Use this menu cell to select a
range for the flow rate display
screen .
Use this menu cell to select
either volumetric or mass flow
total units .
Use this menu cell to set the
resolution of the totalizer .

Resetting the Totalizer registers clears all total data accu-
mulated during operation.
Note: In Dual-Beam mode, the Totalizer operates only on
the virtual system channel (Ch 3). Therefore, in this case,
the CLEAR trigger would be <F3> <1>
Invoking the NOTOT command disables the Totalizer. To-
talization will not resume until you repeat the Fn and Nu-
meric 2 key sequence. When you activate NOTOT, an N
precedes the TOTAL symbol (i.e., [NTOTAL]) on the LCD
Screen.
The LAPTOT command freezes the Totalizer screen dis-
play. However, the flow computer will continue to update
its internal registers. The flow computer will show the cur-
rent total when you repeat the F1 - Numeric 3 key sequence.
When you activate LAPTOT, an L precedes the TOTAL
symbol (i.e., [LTOTAL]) on the LCD Screen.
Clears the Batch Sample totalizer register. See Batch/
Sample Tot.
