calculations
MULTICAL
603
operates
with
15
different
energy
formulas,
E1,
E2,
E3,
E4,
E5,
E6,
E7,
E8,
E9,
E10,
E11,
A1,
A2,
dE
and
cE,
which
are
all
calculated
parallel
with
each
integration,
irrespective
of
how
the
meter
is
configured.
E8
and
E9
are
used
as
a
basis
of
the
calculation
of
average
temperatures
of
inlet
and
outlet,
whereas
E1
and
E3
are
used
for
heat
and
cooling
measurement,
respectively.
E4
to
E7
are
used
in
a
number
of
energy
applications
that
are
shown
below.
A1
and
A2
are
used
as
a
basis
for
discount/surcharge
based
on
the
outlet
temperature
(see
paragraph
7.1.3).
