Press the DISPLAY button briefly to
switch between the TOTAL 1 and
TOTAL 2 BATCH and FLOWRATE
(if applicable). 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.
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.
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" calibration. 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 oth-
er units of measure programmed
into it. If so, holding the CALI-
BRATE 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).
(some models)
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 modi-
fied at any time using the calibration
procedure described in the Calibra-
tion Section. Totals 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 operating con-
ditions. 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:
Low Flow meter 0.3 GPM (1 LPM)
1 inch meter
2 inch meter
The use of a uniformly dependable,
accurate calibration container is
recommended for the most accurate
results. For best results, the meter
should be installed and purged of air
before field calibration.
Due to high flowrate, it is strongly
recommended that Field Calibration
of a Two Inch Meter be completed
with a combination of volume and
weight using fine resolution scales.
