Meter Calibration

7. Dispense component A into beaker.
a. To avoid splashing, slowly open sampling
valves.
b. For more accurate calibration, adjust the valve
to dispense at a flow rate similar to your produc-
tion spray flow rate.
c. Dispense a minimum of 250 cc; make sure
enough material is dispensed to accurately read
the volume with your beaker.
d. Close sampling valve tightly.
8. The volume that the ProMix measured displays on
the EasyKey.
9. Compare the amounts on the EasyKey to the
amount in the beakers.
NOTE: For maximum accuracy, use a gravimetric
(mass) method to determine the actual volumes dis-
pensed.
10. If the screen and actual volumes are different, enter
the actual dispensed volume in cc for A or Solvent
Volume field, and press the Enter key
.
If the value was substantially different, repeat the
calibration process.
NOTE: If the screen and actual volume is the same
or if for any reason you want to cancel the calibra-
tion procedure, scroll to Abort on the Calibration
Screen menu and press the Enter key
.
11. After the volume for A or Solvent is entered, the
K-factor is calculated and shows it on the Calibra-
tion Screen.
NOTE: K-factor values on the screen are viewable
only. If needed, you can manually edit the K-factors
in Advanced Setup Screen 4 (page 37) or Recipe
Setup Screen 5 (page 43).
12. Always purge sampling valves after calibrating
meters. Use one of the following methods.
Follow the Solvent Push Feature procedure,
page 101.
Place the sampling valve fluid tubes into a com-
patible cleaning fluid (TSL or solvent) or cap
them.
NOTE: If fluid hardens in sampling tubes, replace
them with 5/32 in. or 4 mm OD tubing.
13. Make sure both sampling valves are closed and
both fluid shutoff valves are fully open.
14. Before you begin production, clear the system of
solvent and prime it with material.
a. Go to Mix mode.
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 92.
