See the user manuals for the pump and other system
components to ground the following:
D Pump: Follow the manufacturer’s recommenda-
tions.
D Air and fluid hoses: Use only grounded hoses.
D Air compressor: Follow the manufacturer’s recom-
mendations.
D Fluid supply container: Follow your local code.
Factory Settings
The meter is factory calibrated for 10W–30 oil, and the
default unit of measurement is quarts. For other fluids
and different units of measurement, see Changing the
Measurement Units and Calibration Factor on
page 7.
D To maintain grounding continuity when you flush or
relieve pressure, always hold a metal part of the
valve firmly to the side of a grounded metal pail,
then trigger the valve.

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:
