GAS
—Pushing GAS scrolls through the gas list.
The default
gas is air
. The selected gas appears on the display under the
GAS button.
4
MODE
—Push MODE to switch between operating modes.
There are two operating modes (Flow and GC) in the

—Push OFF to turn the unit power off from any operating
mode.
Low battery indicator
The low battery (LO BAT) indicator
appears in the lower right corner of the display window (just
above the mode indicator) if the batteries run below a certain
voltage level.
RS-232 Output
The Flow Tracker Series flowmeters are
equipped with a serial RS-232 output that toggles with the
selected operating mode. All parameters in the selected mode
are output in space-delimited format for data collection and
analysis. No special software is required; any terminal program,
such as HyperTerminal
®
, which comes packaged with all
N O T E
It is very important that the gas being measured is selected to get an
accurate flow rate measurement.
C A U T I O N
To avoid inaccurate readings, change the batteries when the LO BAT
indicator is displayed. Low power can result in inflated temperature
sensor readings, which affect the expected gas viscosity and mass
flow calculations.
N O T E
The
auto-off
feature automatically shuts the flowmeter off after
approximately 5 minutes of continuous no flow (less than 4 mL/min)
condition. This applies
only
under battery power. The auto-off feature is
disabled when power is supplied via an AC to DC adapter.
