You can recalibrate the meter as follows:

3a. If the unit of measurement is liters, dispense exactly one liter of fluid into a calibrated

1-liter container. If the unit of measurement is gallons, pints, or quarts, dispense exactly one quart of fluid into a calibrated 1-quart container. For proper calibration, you must dispense the exact amount, according to the markings on the container.

After dispensing, the displayed number is the new calibration factor. The new calibration factor must be within 20 percent of the fac- tory default value [in the range of 294--442 quarts (310--467 liters)], or it will not be accepted.

The following table lists approximate calibra- tion factors for different fluids. Your calibra- tion number may vary slightly due to temper- ature or flow rate.
