Calibration Checks

Solvent Meter Calibration

1.The meter and lines must be primed with solvent before doing the calibration. See Prime and Fill the System, page 20.

2.If the display is on a Run Mode screen, press

to access setup screens.

3.Scroll to Calibrate in the menu bar.

4.Scroll to Calibrate Screen 3, page 79.

5.Press the soft key to initiate the calibration.

NOTE: For maximum accuracy, use a gravimetric (mass) method to determine the actual volumes dispensed.

NOTE: Verify that the fluid line is filled and at the proper pressure before calibrating. Air in the line or pressure that is too high may cause incorrect calibration values.

6.Trigger the gun into a graduated cylinder. Dispense a minimum of 500cc of material.

7.The volume that the unit measured displays on the screen.

8.Compare the amount on the screen to the amount in the graduated cylinder.

NOTE: If the value is substantially different, repeat the calibration process.

9.Enter the amount of solvent dispensed in the Measured Volume field on the screen.

10.After the measured volume is entered, the controller calculates the new solvent meter K-factor and displays it on the screen. The standard meter K-factor is 0.021 cc/pulse.

11.Press to accept the calibration. Press to cancel the calibration and retain the previous K-factor.
