DIRECTIONS FOR USE
Safety
regulations
(in
accordance
with
|EC
348)
Before
connecting
the
instrument
to
the
mains
(line),
visually
check
the
cabinet,
controls
and
connectors
etc.,
to
ascertain
that
no
damage
has
occurred
in
transit.
If
any
defects
are
apparent,
do
not
connect
instrument
to
the
mains
(line).
The
instrument
must
be
dis-
connected
from
all
voltage
sources,
and
any
high
voltage
points
discharged
before
any
maintenance
or
repair
work
is
carried
out.
If
adjustments
or
maintenance
of
the
operating
instrument
with
covers
removed
is
inevitable,
it
must
be
carried
out
only
by
a
skilled
person
who
is
aware
of
the
hazards
involved.
In
normal
Operation
the
double-insulated
power
supply
obviates
the
need
of
a
safety
ground.
WARNING:
IT
MUST
BE
BORNE
IN
MIND
THAT
IN
ALL
MEASUREMENTS
THE
FRAME
GROUND
OF
THE
OSCILLOSCOPE
IS
RAISED
TO
THE
SAME
POTENTIAL
AS
THAT
OF
THE
MEASURING
GROUND
PROBE
CONNECTION.
NEITHER
THE
PROBE’S
GROUND
LEAD
NOR
THE
FRAME
GROUND
SHALL
BE
CONNECTED
TO
LIVE
POTENTIALS.

4.1.
4.2.
Local mains (line) connection
Before
connecting
the
instrument
to
the
mains
(line),
make
sure
that
it
is
set
to
the
local
mains
(line)
voltage.
On
delivery,
the
instrument
is
set
to
110
V,
220
V
or
240
V,
which
is
indicated
on
the
rear
of
the
instrument.
If
the
instrument
has
to
be
set
to
another
voltage
as
indicated,
contact
your
local
service
organisation.

Slide switch; in combination with the TIME/DIV
switch selects the time coefficients. In A&B-mode
the display is chopped in position ms and
alternated in position Us.
Slide switch; allows increase of the horizontal
deflection by a factor of 5.
In combination with the Us/ms switch, selects
the time coefficients from 0.5 Us/DIV to
200 ms/DIV in a 1-2-5 sequence.
In the position X via A, horizontal deflection is
determined by the channel A input signal
(bandwidth < 2 MHz).
CAUTION: Extended high intensity may
damage CRT especially with a stationary or
slow-moving spot.
Slide switch; triggering is effected on the signal
derived from channel A or B, depending on the
switch position.
Slide switch; enables triggering on the positive-
going (+) or negative-going (—) slope of the input
signal.
Slide switch; the time base can trigger either on a
signal derived from channel A or B, or on a signal
applied to BNC connector EXT.
Slide switch; normal triggering. DC component
of the trigger signal is blocked.
TV line or TV frame synchronisation is obtained.
(Frame in position ms, and line in position ps).
BNC socket for external trigger input.
