The model number of your computer
is displayed on the lower front side
of the computer.
INSTALLATION
If you ordered your computer elec-
tronics with a turbine housing, it is
installed at the factory. If you ordered
your computer separately from your
turbine, simply mount the computer
on the turbine with the four screws
at the corners of the faceplate. Make
sure the seal is fully seated before
tightening the screws. If you ordered
the computer with turbine and an ac-
cessory module, please review and
thoroughly understand all installation
instructions before proceeding.
All GPI turbines are designed to
measure flow in only one direction.
The direction is indicated by the ar-
row cast-molded in the turbine outlet.
If the opposite direction is desired,
simply rotate the computer electron-
ics 180 degrees prior to installation.
Avoid electronically "noisy" envi-
ronments. Install the computer at
least 6 inches (15.2 cm) away from
motors, relays or transformers.
Verify Accuracy
Before use, check the accuracy and
verify calibration. Make sure there
is no air in the system. Measure an
exact known volume into an accurate
container. Verify the volume against
the readout or recording equipment.
If necessary, use a correction fac-
tor to figure final volume. For best
results, accuracy should be verified
periodically as part of a routine main-
tenance schedule.

OPERATION
Computer Display
All operations are reflected in the
LCD readout. The large center dig-
its indicate amounts, where smaller
words or "icons" located above and
below indicate specific information
regarding totals, flow, calibration and
units of measure.
Activate the Meter
Computer is on continuously and
always ready to perform. The
computer is powered by field
replaceable batteries. When display
becomes dim, faded or the low battery
message appears (see below),
the batteries need to be replaced.
Reference the Maintenance Section
for details.
Batch and Cumulative
Totals
The computer maintains two totals.
The Cumulative Total provides con-
tinuous 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.
