Press the Program key to advance to the next
program step in System Setup mode. It is not
necessary to program all twelve presets
unless they are to be used. Program the
number of presets required. Press the
Program key again to continue in System
Setup mode.
Reference Pressure
Before entering the reference flow, determine
the pressure at which the flow will be
referenced. Use the Plus or Minus keys to
adjust the value of the pressure (PSI or Bar)
to be used as flow reference. The pressure
selected to reference flow is not critical (any
pressure can be used). Select a pressure that
is close to normal operating pressure or select
a pressure from the flow rate chart for the
nozzles being used. After the reference
pressure has been selected, press the
Auto/Man key to advance to the reference
flow for preset #1.
