Batch Ratio Dispense Test - Graco XM Series Operation Manual

Batch Ratio Dispense Test

NOTE:
This test dispenses a calculated volume of each fluid
based on ratio. The two fluids combined equal the batch
size selected.
Follow this procedure to dispense a batch (into one con-
tainer) for touch-up work or to verify a ratio setting (use
separate containers for fluids A and B).
Dispense into a container with graduations no greater
than 5% of each component. If the ratio is known by
weight, use a scale for greatest accuracy.
1. Enter Test mode in the run (fluid control) screen.
See Test Screens on page 71. Select
