The
meter
can
use
both
battery
and
mains
supply.
In
case
of
battery
supply,
a
reading
interval
of
10
seconds
or
higher
does
not
result
in
a
reduction
of
the
meter’s
specified
battery
lifetime.

more
about
battery
lifetimes
in
paragraph
10.3
In
case
of
battery
supply,
it
is
recommended
to
use
the
highest
possible
communication
speed
as
this
results
in
the

power
consumption.

for
the
meters’
battery
lifetimes.
