2. To change terminal block connections,
loosen the appropriate screws. Reconnect
the wires in the proper positions and tighten
the screws.
3. Install the batteries. Make sure the positive
post is in the correct position.
4. Position the module on the turbine housing.
To avoid moisture damage, make sure the
seal is fully seated. Tighten the four screws
on the front of the module.
Ten feet (3 m) of cable is provided with the
module. Trim the cable to desired length or
extend it as necessary.
Verify Meter Accuracy
Before using, check the meter's accuracy and
verify calibration.
1. Make sure there is no air in the system
by starting the flow until it runs steadily.
Then, stop or divert the flow using a valve
or nozzle.
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 with 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 zeroes 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
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.
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.
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 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).
