Configuration - GPI GM Serie Guía De Operación

CONFIGURATION

Configuration determines what information is present
on the LCD display. For instance, total, flowrate, type
of calibration, etc.
The Display has been programmed with many features,
which can be enabled by the end user through the con-
figuration process. By disabling unnecessary features,
day-to-day flowmeter operation can be greatly simpli-
fied, making the unit easier to use. Alternately, there are
several features not found in the default configuration.
Available features include:
• 0 to 3 totals, either resettable (Batch) or non-reset-
table (Cumulative).
• Flowrate or no flowrate. Available in units per minute,
hour or day.
• Three different field calibration methods: K-factor
entry, Dispense/Display or % Correction Factor.
• Various units of measure (some or all): GL (gallon),
LT (litre), IGL (imperial gallon), QT (quart), CF (cubic
feet), CM (cubic meter), BL (42 gal. barrel), CC (cubic
centimeter) or OZ (ounce).
Changing Configuration Settings
Access to the configuration settings require a specific
procedure and a pin code available through the GPI
website at www.gpimeters.net or call GPI Customer
Serivce at 888-996-3837.
OPERATION
Computer Display
All operations are reflected in the LCD readout. The large
center digits indicate amounts, where smaller words
or "icons" located above and below indicate specific
information regarding totals, flow, calibration and units
of measure.
Computer is on continuously while the loop is powered.
Batch and Cumulative Totals
The computer maintains two totals. The Cumulative
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.
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 liters 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 pos-
sible 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, dif-
ferent 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
derived from the field calibration are invoked when the
FAC icon is no longer visible on the top line of the display.
CALIBRATION
Field Calibration Procedures
(K-Factor Method)
If the display was purchased as an accessory or remote,
then the field calibration method set at the factory is
K-factor Entry method.
This method allows the user to key in a single point
K-factor value that represents the meter it will be used
with. K-factor values for specific meters can be found
on the meter itself, in Table 1 or www.gpimeters.net.
