Changing the Measurement Units and
Calibration Factor
NOTE: A one liter Weights and Measures approved
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 typi-
cal temperature range. If you will use the meter to dis-
pense 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 mea-
surement is displayed. See the list below:
GAL = gallons
QTS = quarts
PTS = pints
L = liters
3. Press the TOTAL button to go to the CALIBRATION
menu.
NOTE: If you do not want to change the calibration
factor, press the TOTAL button again to use the
existing calibration factor and to resume normal
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 calibration
factor and resume normal operation.
NOTE: The number on the display is the calibration
factor number. It must be in the range of 311 to 466.
The following table lists approximate calibration fac-
tors for different fluids. Your calibration number may
vary slightly due to temperature or flow rate.
