Operation
Changing the Measurement Units and Calibration Factor
NOTE: A one liter Weights and Measures ap-
proved container is required for calibration.
This meter is factory calibrated to dispense 10W–30
motor oil at 70_ F (21_ C) at 2.0 gpm (7.6 lpm) and is
acceptably accurate for most common fluids over a
typical temperature range. If you will use the meter to
dispense antifreeze or other approved fluids, you may
have to recalibrate it for greater accuracy.
1. Press and hold both the TOTAL and RESET
buttons for four seconds.
The numbers on the display turn off, and the
L (for liters) and CAL (for calibration) icons turn
on.
2. Set the units of measurement by repeatedly press-
ing the RESET button until the correct unit of
measurement is displayed. See the list below:
GAL = gallons
QTS = quarts
PTS = pints
L = liters
3. Press the TOTAL button to go to the CALIBRA-
TION menu.
NOTE: If you do not want to change the calibra-
tion factor, press the TOTAL button again to use
the existing calibration factor and to resume nor-
mal operation. To change the calibration factor,
do steps 4 and 5.
4. Dispense exactly one liter of fluid into a calibrated
1-liter container. For proper calibration, you must
dispense exactly 1 liter according to the markings
on the container.
NOTE: If you dispense more than 1 liter, press
the TOTAL button to exit the CALIBRATION
menu. Pressing the TOTAL button at this point
does not save the new calibration factor. You must
complete steps 1 to 5 change the calibration
factor.
5. Press the RESET button to store the new calibra-
tion factor and resume normal operation.
NOTE: The number on the display is the calibra-
tion factor number. It must be in the range of 311
to 466. The following table lists approximate
calibration factors for different fluids. Your calibra-
tion number may vary slightly due to temperature
or flow rate.
