Summer/winter
time
adjustment
(AFR)
MULTICAL®
603
is
available
with
configuration
for
DST
(Daylight
Saving
Time
~
summer/winter
time).
The
meter’s
country
code
determines
the
DST
‐
configuration
algorithm,
so
that
it
corresponds
to
the
DST
regulations
of
the
country,
for
which
the
meter
is
intended.
If
the
meter
is
configured
with
DST
and
you
do
not
want
to
use
it,
the
DST
‐
function
can
be
disabled
in
the
PC
‐
program
METERTOOL
HCW.
The
DST
‐
function
has
direct
influence
on
the
meter’s
internal
clock
and
time
‐
controlled
tariff
limits.
Time
stamps
for
loggings
of
events
and
values
are
saved
in
standard
time
together
with
information
on
the
current
DST
offset.
The
current
DST
offset
is
applied
to
all
logged
time
stamps
when
the
DST
function
is
active,
the
applied
DST
offset
is
removed
from
time
stamps
if
the
DST
function
is
deactivated
in
the
meter
and
vice
versa
if
the
DST
function
is
reactivated.
DST
and
tariffs:
The
time
‐
controlled
tariff
is
influenced
by
the
DST
offset.
The
entered
tariff
limits,
for
example,
will
be
moved
an
hour
forward
at
DST
start
and
an
hour
backwards
at
the
end
of
DST
(Danish
example).
If
the
DST
function
is
disabled
after
a
period
in
operation,
the
time
limits
will
always
follow
standard
time.
Accumulated
energy
in
the
tariff
registers
remains
unchanged
and
thus
reflects
the
time
limits
with
enabled
DST
‐
function.
The
same
applies
vice
versa
if
the
DST
‐
function
is
reactivated.
DST
and
loggers:
The
logging
time
follows
normal
time.
For
example,
a
meter
with
enabled
DST
‐
function,
which
logs
data
at
00.00
during
winter
time,
will
log
data
at
01.00
a.m.
during
summer
time
(Danish
example).
If
the
DST
‐
function
is
disabled
after
delivery
and
historical
logger
values
are
subsequently
read,
the
DST
offset
of
previous
values
will
reflect
the
new
configuration
and
be
removed
from
the
time
stamp.
See
example
in
below
table.
Read
logging
times
will
always
reflect
the
current
DST
status.

If
the

of
a

If

will
be

from

and
readout
of
logging
data:
Data
can
either
be
read
from
a
register,
which
includes
time
in
standard
time
and
DST
offset
as
two
separate
parameters,
or
alternatively
from
a
register,
which
includes
time
comprising
DST
offset
as
a
parameter.
If
the
DST
‐
function
is
disabled
after
delivery,
information
on
the
DST
offset
will
be
removed
from
time
stamps
related
to
the
historical
values.
