Connect
the
monitor
to
an
AC
power
source.
Turn
on
the
monitor.
2.
Rotate
the
trim
knob
to
highlight
CO
2
numerical
area
and
then
press
the
trim
knob
to
display
the
CO
2
menu.
3.
Verifying
that
Capno
Measurement
is
set

Test
#1:
Display
Accuracy
a.
Connect
the
10%
calibration
gas
cylinder
with
the
valve
to
the
sampling
tube
connected
to
the
water
trap
of
the
monitor.
b.
After
passed
the
warm
up
time
(about
3
minutes),
repeat
3
or
4
times
turning
on
and
off
the
valve
of
the
gas
cylinder
with
the
interval
of
1
to
2
seconds.
c.
Verifying
that
the
monitor
displays
76mmHg
±
2mmHg
in
CO
2
numerical
area.
5.
Test
#2:
Flow
Rate
a.
Connect
the
flow
meter
to
the
sampling
tube
connected
to
the
monitor.
b.
Connect
a
sampling
tube
to
the
other
side
of
the
flow
meter
and
make
the
other
side
of
the
sampling
tube
open.
c.
Verify
that
the
flow
rate
is
between
150
±
2mmHg.
6.
Test
#4:
Occlusion
a.
Block
the
sample
input.
The
module
should
enter
the
ʺ
occlusion
ʺ
state.
Verify
that
it
does
correctly
enter
this
occlusion
state.
b.
Unblock
the
input.
Verify
that
after
the
modules
occlusion
sequence
of
high
flow
rates
and
valve
actuations
the
occlusion
message
disappears
and
the
module
restores
normal
function.

Test
#5:
EtCO
2
Calibration
To
perform
a
Zero
Calibration:
The
user
is
required
to
apply
a
0%
CO
2
gas,
or
“zero”
gas,
during
the
steps
of
a
Zero
Calibration.
a.
Select
a
well
ventilated
room
to
perform
the
calibration.
b.
Make
sure
the
monitor
has
been
operating
for
at
least
5
minutes
prior
to
the
Zero
Calibration.
c.
Attach
the
CO
2
scrubber
to
the
water
trap
inlet
according
to
the
CO
2
scrubber
“Directions
for
Use”
(or
attach
a
0%
medical
‐
grade
gas
source).
Now
the
monitor
operates
for
one
minute.
d.
After
approximately
one
minute,
observe
the
CO
2
reading.
The
CO
2
reading
should
be
between
0.0%~0.3%
with
well
‐
ventilated
room
air.
e.
Proceed
with
the
zero
gas
phase
of
the
calibration
as
defined
by
the
host
system.
f.
Disconnect
the
CO
2
scrubber
(or
gas
source)
from
the
water
trap
after
the
zero
gas
calibration.
