Check
the
product
specifications
Before
starting
to
use
this
product,
check
the
product
specifications
that
can
be
found
in
this
manual
or
the
basic
information
located
on
the
back
panel
of
the
product.
The
detailed
product
technical
specifications
can
be
found
in
Section
7.
For
a
specific
application,
the
pressure
rating
must
not
be
higher
than
the
system
pressure
to
be
measured,
and
the
flow
range
should
also
be
within
the
specified
ones.
In
most
cases,
the
use
of
a
high
full
‐
scale
ranged
meter
for
the
very
low
flow
rate
measurement
often
results
in
erroneous
data.
The
gas
to
be
measured
must
also
be
consistent
with
that
specified
by
the
product.
Be
particularly
cautious
about
the
supplied
voltage
indicated
in
the
specification.
A
higher
voltage
may
lead
to
irrecoverable
damage,
and
a
lower
voltage
will
not
power
the
product
for
any
desired
functions.
For
the
best
performance
of
the
product,
it
is
advised
that
the
gas
to
be
measured
must
be
clean
and
free
of
particles
or
other
foreign
materials.
5.2
Check
the
leakage
Check
gas
leakage
before
any
measurement.
If
it
is
needed,
the
pressurized
nitrogen
or
air
can
be
used
for
the
leakage
check.
5.3
Power
the
meter
and
digital
data
connection
Although
this
product
complies
with
the
CE
‐
required
EMC
regulations,
it
also
requires
the
product
to
be
used
according
to
the
standard
electrical
device
practice.
For
general
‐
purpose
usage,
the
meter
can
be
powered
by
4
AA
batteries.
Be
sure
to
select
the
batteries
with
safety
proof
and
within
the
expiration
date.
Do
not
use
batteries
without
a
known
manufacturer
and
expiration
date.
For
models
with
control
valves
or
for
extensive
usage,
it
is
recommended
to
have
the
meter
powered
with
external
DC
power
or
an
AC
‐
DC
adapter.
Make
sure
the
supply
voltage
is
within
the
range
of
the
specified
ones
in
Section
7.
Before
connecting
the
product
with
the
external
power,
make
sure
the
standard
electrical
device
precautions
such
as
EDS
(electrostatic
discharge)
and
DC
voltage
are
observed.
Excessive
electrostatic
discharge
may
damage
the
product.
