not included.
Negative – Total negative (reverse) flow; positive (forward) flow
not included.
The selected totalizer mode applies to all connected instruments.

A totalizer reset can also be performed via HyperTerminal with
the SZ command (refer to Table A-1).
HADFM Totalizer
Limitations
The totalizer for a connected HADFM will always totalize net
flow, regardless of the selected mode. This does not affect total-
izers for any other connected instruments. The accQcomm cannot
zero an HADFM totalizer. Whenever the HADFM is reset, the
accQcomm’s corresponding totalizer will also reset.
2.2.4 Instruments By default, only Instrument 1 will be set as active when you click
the Site tab; the other two will be set to Inactive. Use the
pull-down menus for Type to select between Inactive, ADFM,
accQmin, or HADFM for inputs 1, 2, and 3, and enter an identi-
fying name for each instrument.
