2. Meter an exact known volume into an ac-
curate container. For best results, meter with
one continuous full stream.
3. Check the volume against the display or
recording equipment. If the amount metered
is accurate, further calibration is not neces-
sary. If not, refer to the Calibration Section
for further instructions.
OPERATION
Computer Display –
Batch and Cumulative Totals
The computer maintains two totals. The Cumula-
tive Total provides continuous measurement and
cannot be manually reset. The Batch Total can
be reset to measure flow during a single use.
The Cumulative Total is labeled TOTAL 1, Batch
Total is labeled TOTAL 2 BATCH.
When the Cumulative Total reaches a display
reading of 999,999 the computer will highlight
an X10 icon. This indicates to the operator that
a zero must be added to the 6 digits shown.
When the next rollover occurs, the computer
will highlight an X100 icon. This indicates to
the operator that two zeros must be added to
the 6 digits shown.
Press the DISPLAY button briefly to switch
between the TOTAL 1, TOTAL 2 BATCH and
FLOWRATE. Press DISPLAY briefly to display
the TOTAL 2 BATCH. Hold the DISPLAY button
for 3 seconds to reset the Batch Total to zero.
When fluid is flowing through the meter, a small
propeller icon is highlighted.
NOTE: Totalization counts total units without
differentiating between gallons, litres or field
calibrated units.
Flowrate Feature
To use this feature, press and release DISPLAY
button until FLOWRATE icon appears. The
factory set time base will be highlighted to the
right of FLOWRATE (M = minutes, H = hours,
D = days). When FLOWRATE is invoked, the
display will be indicating rate of flow.

Reference the Maintenance Section for details.
Factory and Field Calibration
All calibration information is visible to the user
as icons on the top line of the display, above
the numeric digits.
All units are configured with a "factory" calibra-
tion. Both gallons and litres are available ("GL"
or "LT" will be displayed). While holding the
CALIBRATE button, briefly press DISPLAY to
toggle between gallons and litres. This factory
calibration (indicated with FAC) is permanently
programmed into the computer and is not user
adjustable.
NOTE: Your computer may have other units of
measure programmed into it. If so, holding
the CALIBRATE button and momentarily
pressing the DISPLAY button will toggle
through all factory set units. Other possible
units are: IGL (imperial gallon), QT (quart), CF
(cubic feet), CM (cubic meter), BL (42 gal.
barrel), CC (cubic centimeter) or OZ (ounce).
Switching between different units will not corrupt
the Total's contents. For example, in GL mode,
the computer totalizes 10.00 gallons, if the user
switches to LT mode, the display will read 37.85
litres (the same volume, different unit).
The "field" calibration may be set by the user,
and can be changed or modified at any time
using the calibration procedure described in the
Calibration Section. Totals or flowrate derived
from the field calibration are invoked when the
FAC icon is no longer visible on the top line of
the display.
CALIBRATION
Verify Accuracy Before
Beginning Field Calibration
For the most accurate results, dispense at a
flowrate which best simulates your actual oper-
ating conditions. Avoid "dribbling" more fluid or
repeatedly starting and stopping the flow. This
can result in less accurate calibrations.
Make sure you meet the meter's minimum
flowrate requirements:
