Test
The
following
paragraph
briefly
describes
the
various
functions
used
during
test.
The
description
is
divided
into
flow
test
and
calculator
test.
13.3.1
Test
of
flow
sensor
The
high
‐
resolution
volume
can
be
accessed
through
the
serial
interface
or
by
reading
the
display.
Is
used
during
both
standing
and
flying
start/stop.
13.3.2
Test
of
calculator
The
calculator
supports
autointegration,
which
is
used
for
testing
the
accuracy
of
the
temperature
measurement.
Autointegration
counts
a
simulated
volume
over
a
given
number
of
integrations
with
an
evenly
distributed
increase
of
volume.
At
each
integration,
the
temperature
of
the
temperature
sensors
is
measured
and
with
the
simulated
increase
in
volume,
energy
is
calculated.
The
energy
and
an
average
of
the
temperature
measurement
can
subsequently
be
read
either
from
the
display
or
through
serial
communication.
Autointegration
can
be
started
via
the
serial
interface.
Further,
it
can
be
activated
by
a
keystroke
when
the
meter
has
been
legally
unlocked.
If
the
meter
has
not
been
unlocked,
autointegration
can
be
used,
but
it
does
not
increment
volume
and
energy
in
the
legal
registers.
However,
this
requires
that
the
installation
seal
is
broken.
Used
in
connection
with
standing
start/stop.
