Setup
Ratio Type
Fluid ratio can be monitored as either weight-ratio or vol-
ume-ratio. If the ratio type selected is "Volume", the cali-
bration factor for each installed flow meter must be
entered in the calibration factor fields (PF, PG). The cal-
ibration factor is found on the flow meter data sheet
shipped with the machine.
After each shot, the ratio for that shot will be shown on
the Home screen. If weight-ratio is selected, the ratio will
be shown to the left of the piston position graphic. If vol-
ume-ratio is selected, the ratio will be shown to right of
the piston position graphic.
