NOTE: Totalization counts total units
without differentiating between
gallons, litres or field calibrated
units.
Flowrate Feature
To use this feature, press and release
DISPLAY 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 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).
(some models)
The "field" calibration may be set
by the user, and can be changed
or modified at any time using the
calibration procedure described
below in the Calibration Section.
Totals derived from the field calibra-
tion 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
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:
1/2 inch meter
3/4 inch meter
1 inch meter
1-1/2 inch meter 10 GPM (37.9 LPM)
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 1-1/2 and 2 inch meters be
completed with a combination
of volume and weight using fine
resolution scales.
