Patient
Leakage
Current
This
test
measures
patient
leakage
current
in
accordance
with
IEC60601
‐
1,
clause
19,
for
Class
I,
Type
CF
equipment.
Patient
leakage
current
in
this
test
is
measured
from
any
individual
patient
connection
to
earth
(power
ground).
1.
Configure
the
electrical
safety
analyzer
as
recommended
by
the
analyzer
operating
instructions.
2.
Connect
the
monitor’s
AC
mains
power
cord
to
the
analyzer
as
recommended
by
the
analyzer
operating
instructions.
3.
Connect
the
ECG
test
cable
between
the
ECG
connector
on
the
monitor
and
the
appropriate
input
connector
on
the
analyzer.
4.
Turn
on
the
monitor.
5.
Perform
the
patient
leakage
current
test
as
recommended
by
the
analyzer
operating
instructions.
6.
Repeat
the
patient
leakage
current
test
for
the
SpO
2
and
temperature
patient
connections,
using
the
appropriate
test
cables.
Note:
Patient
leakage
current
is
measured
under
various
conditions
of
the
AC
mains
and
protective
earth
conductor.
For
each
condition,
the
measured
leakage
current
must
not
exceed
that
indicated
in
Table
5.
Note:
This
test
requires
a
test
cable
for
each
patient
connector.
For
example,
the
ECG
test
cable
consists
of
the
ECG
cable
connector,
with
all
conductors
shorted
together,
connected
to
a
test
lead
from
the
electrical
safety
analyzer.
Test
cables
for
SpO
2
and
temperature
can
be
configured
in
a
similar
manner,
by
wrapping
each
sensor
end
individually
with
aluminum
foil
filled
with
conductive
gel
(only
enough
gel
to
ensure
conductivity).
Attach
a
wire
to
the
foil
that
is
connected
to
a
test
lead
from
the
electrical
safety
analyzer.
