2.6 THE FLOW/TOTAL UNITS MENU

The Flow/Total Units menu is available after selecting a meter type and measurement channel. Use the

Flow/Total Units menu to select volumetric flow units and an associated time base for the energy and

flow rate and total outputs. 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)

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.

*Use the <F1> key as the “Lead-in command” for 4-Path Totalizer operations.

The LAPTOT command freezes the Totalizer screen

display. However, the flow computer will continue to up-

date its internal registers. The flow computer will show the

current total when you repeat the F1-Numeric 3 key se-

quence. 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.

Resetting the Totalizer registers clears all total data ac-

cumulated 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>.
