5.
Select
to run batch dispense test.
6.
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.
7.
Close recirculation valves, mix manifold inlet ball
valves, and sampling valves.
8.
Place a clean container under sampling valve A.
9.
Press
. Wait until the Metering pump A light
comes on.
10. Dispense fluid A. Slowly open and adjust sampling
valve A (AE) to achieve desired flow. The metering
pump stops automatically when dispense completes
and metering pump A light (DK) turns off and
metering pump B light (DK) turns on.
11. Close sampling valve A (AE).
12. Dispense fluid B as follows:
a.
Batch dispense:
move container under
sampling valve B (AF).
Ratio check
: place clean container under
sampling valve B (AF).
b.
Slowly open and adjust sampling valve B (AF)
to achieve desired flow. The metering pump
stops automatically when dispense completes.
Metering pump B light (DK) turns off.
c.
Close sampling valve B (AF).
13.
Batch dispense:
stir material until mixed.
Ratio check
: compare net weight of A and B
materials dispensed.
Confirm Batch Dispense Test
The Confirm Batch Dispense Test screen displays when
the batch dispense test completes without error. This
screen displays the selected ratio between the metering
pumps and the weight of material dispensed from each
metering pump.
The gray at the bottom of the beaker represents the
weight of material dispensed by metering pump A and
the black at the top of the beaker represents the weight
of material dispensed by pump B.
Enter the weight (in grams) of each sample in the A and
B input boxes. The system will calculate the ratio and
display a check in the box if it is within tolerance. The
result of the test is also entered in the USB log.
