Below
you
see
examples
of
display
readings
of
the
date
and
data
readings.
The
frames
around
the
date
indicate
whether
the
date
is
connected
to
yearly
or
monthly
data.
In
data
readings
of
yearly
data
the
last
two
digits
of
the
year
are
marked
in
frames,
whereas
the
two
digits
for
month
are
marked
for
monthly
data.
Furthermore,
the
symbols
”MIN”
and
”MAX”
are
illuminated
to
indicate
whether
the
values
are
minimum
or
maximum
values.
The
symbol
”LOG”
is
illuminated
for
historical
readings.
Examples of yearly date and data (max. values) for flow
Date of max. this year
Data of max. this year
Date of max. yearly logger
Data of max. yearly logger
Examples of monthly date and data (min. values) for power
Date of min. this month
Data of min. this month
Date of min. monthly logger
Data of min. monthly logger
All
minimum
and
maximum
values
are
calculated
as
the
average
of
a
number
of
current
flow
or
power
measurements.
After
each
averaging
period
the
latest
value
is
compared
to
previous
values,
and
the
new
value
is
saved
if
it
exceeds
the
previous
maximum
value
or
is
lower
than
the
previous
minimum
value.
The
averaging
period
used
for
all
calculations
can
be
selected
in
the
interval
1...1440
min.
in
leaps
of
one
minute.
(1,440
min.
=
24
hours).
The
averaging
period
and
the
target
dates
are
stated
in
the
order.
Read
more
about
order
data
in
paragraph
3.3.
If
not
otherwise
stated
in
the
order,
the
default
averaging
period
of
60
min.
is
used.
This
value
can
later
be
changed
via
SETUP
loop
or
via
METERTOOL
HCW.
Please
note
the
following:
In
the
display
the
date
is
shown
in
the
format
20YY.MM.DD,
but
by
serial
reading
the
time
can
be
stated
too,
and
the
format
then
becomes
YY.MM.DD,
hh.mm.ss.
The
averaging
period
starts
the
moment
the
meter
is
powered,
i.e.
when
the
battery
is
mounted
in
the
meter
or
when
mains
supply
is
switched
on.
Therefore,
the
averaging
period
is
not
necessarily
synchronous
with
the
change
of
day.
Due
to
this
fact
the
min./max.
calculation
is
immune
to
the
clock
setting
as
the
interval
is
kept
intact
at
e.g.
60
or
1440
min.
