7.
One at a time, dispense component A and B into
separate beakers.
a.
To avoid splashing, slowly open sampling
valves (2A, 2B).
b.
For more accurate calibration, adjust the valve
to dispense at a flow rate similar to your pro-
duction spray flow rate.
c.
Dispense a minimum of 250 cc of each com-
ponent; make sure enough material is dis-
pensed to accurately read the volume with
your beaker. The A and B volumes do not
have to be equal or at any particular ratio.
d.
Close each sampling valve tightly.
9.
Compare the amounts on the EasyKey™ Display to
the amount in the beakers.
10.
If the screen and actual volumes are different, enter
the actual dispensed volume in cc for A and B Vol-
ume fields, and press
.
If the values were substantially different, repeat the
calibration process.
11.
After the volumes for A and B are entered, the con-
troller calculates the new flow meter K-Factor and
shows them on the Calibration screen.
.
12.
Always purge sampling valves after calibrating
meters. Use one of the following methods.
•
Follow the Purging Sampling Valves and
Tubes procedure, page 48.
•
Place the sampling valve fluid tubes into a com-
patible cleaning fluid (TSL or solvent) or cap
them.
14.
Before you begin production, clear the system of
solvent and prime it with material.
a.
Select Mix
on the Operator Station.
b.
Trigger the gun into a grounded
metal pail until mixed material
flows from the gun nozzle.
c.
To begin operation, see Start
Up, page 39.
8.
The volume that the ProMix™ II measured displays
on the EasyKey™ Display.
For maximum accuracy, use a gravimetric (mass)
method to determine the actual volumes dis-
pensed.
If the screen and actual volumes are the same or if
for any reason you want to cancel the calibration
procedure, scroll to Abort on the Calibration
drop-down list and press
.

If fluid hardens in sampling tubes, replace them
with 5/32 in. or 4 mm OD tubing.
13.
Make sure both sampling valves (2A, 2B) are
closed and both fluid shutoff valves (1A, 1B) are
fully open.
