Operation

To Verify the Accuracy

1. Use a clean, calibrated container.
NOTE: If using a single container, be sure to clean it
after each dispense.
2. Set the pump air pressure at the lowest possible
setting for dispensing fluid.
3. Place the tip of the nozzle at the bottom of the cali-
brated container.
NOTE: If the tip of the dispense valve does not
reach the bottom of the calibrated container, use a
length of plastic tubing over the tip of the nozzle to
ensure liquid enters the container from the bottom.
4. Trigger the dispense valve slowly. Dispense fluid
until the calibrated container is full.
5. Allow product to sit for 20 minutes, then compare
the actual, physical measurement in the calibrated
container to the measurement interpreted by the
Logic Control Device.
NOTE: The above procedure determines if the meter is
accurately measuring the product and minimizing
testing errors. Some variance may occur depending on
the viscosity of the fluid. If this procedure determines
that the meter is not accurate, recalibrate the Logic
Control Device. Recalibrating will vary depending upon
the Logic Control Device settings.
