Batch Dispense or Ratio 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 the dispensed ratio
(use separate containers for fluids A and B).
When checking the ratio, use a scale to tare the two
containers then weight the dispensed materials.
1. Close mix manifold material ball valves.
2. Close recirculation ball valves.
3. Pressurize the material lines:
d. Set metering pump air regulator pressure to
zero. Open metering pump air valve.
e. At the main run (fluid control) screen, press
to enter manual pump run mode.
f. Adjust metering pump air regulator pressure to
50 psi (0.35 MPa, 3.5 bar).
g. Press .
h. When both the A and B metering pumps stall,
press .
4. Enter Test mode in the run (fluid control) screen.
See Test Screens on page 69. Select

batch dispense test.
5. Adjust dispense amounts from 500 ml to 2000 ml (in
250 ml increments) by pressing to open the
drop-down box. Then press and to select
the desired value. Press to select that value.
6. Close recirculation valves, mix manifold inlet ball
valves, and sampling valves.
