To Verify the Accuracy of an
Electronic Meter
1. Use a clean, calibrated container. If using a single
container, be sure to clean it after each dispense.
2. Have pump air pressure at the lowest possible set-
ting for dispensing fluid.
3. Put the tip of the nozzle at the bottom of the cali-
brated container.
4. 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 liq-
uid enters the container from the bottom.
5. Trigger the gun slowly so the fluid immediately cov-
ers the tip of the dispense valve.
6. Allow product to sit for 20 minutes, then compare
the actual, physical measurement in the calibrated
container to the measure displayed on the meter.
NOTE: The procedure above will determine if the meter
is accurately dispensing the product and minimize test-
ing errors. Some variance may occur depending on the
viscosity of the fluid. If this procedure determines that
the meter is not accurate replace the meter or the elec-
tronics as necessary.
For Maximum Dispensing
Accuracy
(gallon/quart/pint meter only)
Set the meter to dispense in pints or quarts when dis-
pensing 1 gallon or less.
Always press the RESET key pad to clear the meter
before a new dispense cycle.
