8. Dispense component A or B 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. The A and B vol- umes do not have to be equal or at any particu- lar ratio.

d.Close sampling valve tightly.

9.The volume that the ProMix measured displays on the EasyKey.

10.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.

11.If the screen and actual volumes are different, enter the actual dispensed volume in cc for A, B, or Sol-

vent 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.

Meter Calibration

12.After the volume for A, B, or Solvent is entered, the ProMix 2KS controller calculates the new flow meter K-factor and shows it on the Calibration 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 41) or Recipe Setup Screen 5 (page 46).

13.Always purge sampling valves after calibrating meters. Use one of the following methods.

•Follow the Purging Sampling Valves and Tubes procedure, page 98.

•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.

14.Make sure both sampling valves are closed and both fluid shutoff valves are fully open.

15.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 89.
