Activating the Meter
The computer is on continuously
and always ready to perform. The
computer is powered by off-the-shelf
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 continuous
measurement and cannot be manually
reset. The batch total can be reset
to measure flow during a single use.
The cumulative total is displayed on
the small display on the right, labeled
TOTAL. The batch total is displayed
on the large centered display and is
labeled BATCH TOTAL.
When the BATCH TOTAL reaches a
display reading of 999.9 and the next
rollover occurs, the floating decimal
adjusts to the right and the BATCH
TOTAL continues displaying in whole
units only.
Press and hold the RESET button for
about 3 seconds to reset the BATCH
TOTAL to zero.
