Calibration
of
MULTICAL®
403
using
METERTOOL
HCW
In
order
to
calibrate
MULTICAL®
403
calibration
equipment
is
required,
and
calibration
data
must
be
entered
in
METERTOOL
HCW.
15.1
Calibration
equipment
Calibration
equipment
is
used
for
calibration
of
the
calculator
MULTICAL®
403.
Different
temperatures
are
simulated
on
the
two
temperature
sensor
inputs
(t1
and
t2).
Together
with
the
volume
simulation
(autointegration)
they
form
the
basis
of
the
calibration
of
the
energy
calculation,
E1
and
E3.
The
equipment
was
primarily
constructed
for
use
in
laboratories
testing
and
verifying
meters
but
can
also
be
used
for
performance
testing
the
meter.
METERTOOL
HCW
(6699
‐
724)
is
used
for
configuration,
test
and
calibration.
Calibration
equipment
for
MULTICAL®
403
includes
USB
interface.
During
installation
this
interface
creates
a
virtual
COM
port
which
figures
on
the
computer
as
an
optional
COM
port
in
METERTOOL
HCW.
As
the
virtual
COM
port
only
exists
when
the
equipment
is
connected,
the
calibration
equipment
must
be
connected
to
the
computer
before
METERTOOL
HCW
is
started.
Note:
Calibration
does
not
include
temperature
sensors
and
flow
sensor.
The
calibration
equipment
comes
in
two
different
types,
depending
on
the
type
of
MULTICAL®
403
to
be
calibrated
(Pt100
or
Pt500).
Both
calibration
equipments
calibrate
the
meter
as
both
heat
meter
and
cooling
meter
via
five
calibration
points.
