Appendix A
Batch Dispense or Ratio Test
This screen enables users to dispense a selected total
volume of material on ratio. For example, 1000 ml at 4:1
= 800 ml of A + 200 ml of B. The total batch volume can
be selected from the drop down menu.
When the pump is active it flashes in black on the
screen. When the pump completes dispensing it
displays in gray on the screen.
If the system ratio mode is by volume, pressing
will allow the test to be run either by measuring volumes
or weights. If system ratio mode is by weight, then the
displaced materials must be measured by weight.
Confirm Batch Dispense Test
This screen displays when the batch dispense test
completes without error. This screen displays the
selected ratio between the pumps and the volume of
material dispensed from each pump. The gray at the
bottom of the beaker represents the volume of material
dispensed by pump A. The black at the top of the
beaker represents the volume of material dispensed by
pump B.
There are three variations that affect how the screen is
used:
