Flow Tracker 1000/2000 User Information
Each operating mode displays all of the parameters and each
parameter has a button associated with it. The buttons for the
parameters that are common to all modes, GAS and MODE, are
labeled directly. The "dynamic parameters", which are specific
to certain modes, are labeled on the display.
Dynamic parameters are either active or passive. Active
parameters are directly affected by the flow and are constantly
changing. Active parameters can be moved to the primary
display by pushing the button associated it. Passive parameters
are generally variables that require input from the user. The
passive parameters buttons are generally used to select the
value of the variable.
1 ON—To turn the unit on, press and hold the ON button for
approximately a ½-second.
Should the unit fail to come on as expected, push the OFF button then
press and hold ON.
2 ZERO—Pushing ZERO tares the flowmeter and provides it
with a reference point for zero flow. This is a very important
step in obtaining accurate measurements. It is good
practice to "zero" the flowmeter each time it is turned on. If
the flow reading varies significantly from zero after an initial
tare, give the unit a minute or so to warm up and re-zero it.
If possible, zero the unit near the expected operating pressure by
positively blocking the flow downstream of the flowmeter prior to pushing
the ZERO button. Zeroing the unit while there is any flow will directly
affect the accuracy by providing a false zero point. If in doubt about
whether the flow is positively blocked, remove it from the line and
positively block both ports before pressing the ZERO button.
