Flow Tracker Series 1000/2000
Rel. = (Temperature difference between the two sensors
when last zeroed) – (Present temperature difference
between the two sensors)
Thus, if the unit is completely warmed up and zeroed in air, the
relative conductivity indicator will read approximately zero
until a leak is detected. If a gas with a greater conductivity than
air is introduced, more current will be required and the Rel.
reading will increase positively. If a gas with a lower
conductivity than air is introduced, less current will be required
and the Rel. reading will go negative.
Sound on/off
This indicator is located in the bottom center of
the display above the dynamic label “Sound”. The unit defaults
in sound off. The sound can be toggled on and off simply by
pushing the button located under the dynamic label. The sound
is normally a slow intermittent tick sound that becomes more
frequent with a change (either positive or negative) in the
thermal conductivity from air. When measuring gross leaks, the
tick sounds merge into a constant tone, indicating a large leak.
Gas select
The selected gas is shown in the upper right hand
corner of the display. Available gases are listed in
Low battery indicator (LO BAT)
The low battery indicator,
located just above the mode indicator in the lower right corner
of the display, appears if the batteries run below a certain
voltage level that can affect the accuracy of the flowmeter.
Leak mode indicator
This indicator is located in the lower right
corner of the display and indicates that the unit is in Leak
mode. The operating mode can be changed by pushing the
MODE
button.
C A U T I O N
To avoid inaccurate readings, be sure to 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.
