Terminal
Block
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.

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 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.
