Batch Dispense or Ratio Test

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
container) 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 the Test Screens (page 63).
2. Select to run batch dispense test.
3. Adjust dispense amounts from 500 ml to 2000 ml (in
250 ml increments) by pressing
drop-down box. Then press
the desired value. Press
