Mode
SW
2.xx
You
can
operate
the
DragerService
Mode
with
the
Info
key
and
the
Reset
key.
These
keys
allow
you
to
change
the
set
values,
to
scroll
through
tests,
or
to
confirm
execution
of
a
specific
test.
The
DragerService
Mode
is
subdivided
into
the
Customer
Service
Mode
(CSM)
and
the
Extended
Service
Mode
(ESM).
The
working
language
used
throughout
the
DragerService
Mode
is
English.
The
DragerService
Mode
in
Oxylog
2000
has
17
tests:
•
The
first
five
tests
(Test
001
through
Test
005)
are
specifically
designed
for
the
customer
(CSM),
but
can
also
be
used
by
Drager
service
technicians.
•
The
other
twelve
tests
(Test
011
through
Test
022)
are
part
of
the
Extended
Service
Mode
(ESM)
which
is
used
to
carry
out
calibrations.
These
tests
are
only
accessible
to
Drager
service
technicians.
To
do
so,
the
Drager
service
technician
must
enter
a
numeric
code.
1.1
Definition
of
the
Original
Status
Each
function
in
the
DragerService
Mode
can
be
carried
out
separately.
At
the
beginning
of
the
DragerService
Mode
and
after
completion
of
a

test,
the

Reaction
in
the
Event
of
a
Technical
Error
(TE)
If
Oxylog
2000
detects
a
technical
error,
it
will
show
the
error
number
on
the
display.
The
technical
error
and
the
name
of
the
current
test
are
displayed
alternately
at
2-second
intervals.
In
the
event
of
a
technical
error,
all
tests
can
be
carried
out
normally.
The
message
on
the
display
disappears
as
soon
as
the
technical
error
has
been
corrected.
A
new
Control
PCB
will
generate
the
error
No.
16
(invalid
check
sum
in
the
EEPROM)
before
initial
calibration.
This
technical
error
will
disappear
as
soon
as
all
data
has
been
calibrated.
