CAUTION
Lithium batteries
are used because of their wide tem-
perature operating range and
safety. Any other cell type is not
recommended.
WARNING
To reduce the risk
of explosion do not mix new batteries
with used batteries, or mix batteries
from different manufacturers.
WARNING
To reduce the risk
of a flammable or explosive atmo-
sphere, batteries must be changed
only in a location known to be
non-hazardous.
CAUTION
Always remove
batteries before separating the
computer from the computer
display back housing.
Removing the batteries before
storing the meter will extend
battery life. If the meter’s readout
should become dim, blank or the
low battery message appears
(see below), the batteries should
be replaced. Replacement
batteries are available as an
off-the-shelf general consumer item.
When batteries are disconnected or
fail the Batch and Cumulative Totals
will maintain the value they had.
Factory and Field Calibration Curves
are retained in the meter’s computer
when power is lost.
It is strongly recommended that
battery check and terminal cleaning
be a part of a routine maintenance
schedule. Battery terminals should
be cleaned annually. Batteries can
be replaced without removing the
meter from the piping system.
