5.0 Operating instructions
CAUTION: Do not exceed maximum operating flow rates.
Recalibration may be required if the unit has been sub-
jected to extreme flow rates.
Connect the white probe end tip to the output of the gas flow line to
be measured. Be sure the probe tip connection is completely sealed
around the flow source outlet and is free of leaks (Figure 4).
Press and hold the (power) button until the unit responds
with a regular clicking sound. The ProFLOW will immediately begin
to provide flow measurements (Figure 5). Wait for the measured val-
ues to stabilize. It takes a few seconds for the unit to reach a steady
state with the gas flow line.
To power down the unit press and hold the (power) button
until the unit stops clicking.
The unit is equipped with a timed auto shutoff option (Default: 6
minutes).
