Meter Calibration
Setting Calibration
Located on the side of each meter is a calibration wheel for setting the calibration.
To adjust the meter, proceed as follows:
1
Check the meter by delivering the product into an appropriately-sized Prover Can. If the
amount in the Prover Can does not match with the display (within a tolerance), proceed with
the remaining steps to calibrate the meter.
2
Remove the seal wire from the locking pin.
3
Remove the locking pin and turn the wheel to adjust the measurement. Moving the pin to one
adjacent hole position changes the calibration by 2/3-cubic-inch per 5 gallons dispensed. To
change by half this amount, use the alternate locking pin hole on the opposing side of the
calibration wheel.
