Terminal
Block
Ten feet (3m) 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 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 me-
tered is accurate, further calibration is not
necessary. 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 with TOTAL
1 LOCKED indicating that this total is locked
and cannot be manually zeroed. Batch Total is
labeled with TOTAL 2.
When the Cumulative Total reaches a maxi-
mum reading of 999,999, it will automatically
reset to zero.
Press the DISPLAY button briefly to switch
between the batch, cumulative total, and
flowrate.
NOTE: Totalization counts total units without
differentiating between gallons, litres or
field calibrated units.
