Graco VRM 24F872 Instructions Manual page 37

NOTE: It is recommended that the user calibrate the
machine at the extreme rates where it will be used.
Example: If the machine is to be used at mixed flows
between 300 & 500 grams/second (at 3:1 ratio), cali-
brate the machine at the two 300 and 500 grams/ sec-
ond extremes, then stop the calibration process. The
machine will be very close to all requested flows and
ratios in between.
14. Turn off the "Enable Ratio Check Weight Mode
Entry" option in the Advanced #3 screen. The user
can verify the machine calibration by performing a
ratio check dispense and weighing the A (Red) and
B (Blue) materials.
NOTE: Graco suggests to discard all material dispensed
during a "Learning New Set Point" dispense.
