NOTE: This step may not appear if the console was
not previously programmed for use with a
pressure sensor.
When both a pressure sensor and flow sensor are
installed, the 854 determines when the flow rate has
dropped below the capacity of the flow meter being
used and automatically switches to pressure-based
regulation. When the flow rate once again reaches
an acceptable level for the flow meter to regulate,
the 854 automatically switches back to flow-based
regulation.
• Use the PLUS or MINUS keys to enter
the minimum recommended flow mater, in
GPM or LPM, of the flow meter installed on the
sprayer.
• This information can be located in the flow
meter manufacturer’s literature.
• Minimum flow rates for TeeJet flow meters are
listed in the following table.
• Press the PROGRAM key to return to
accept the value and advance to the next step.
