Important hints

Immediately after unpacking, the instrument should be checked
for mechanical damage and loose parts in the interior. If there
is a damage of transport, fi rst the instrument must not to be
put into operation and second the supplier have to be informed
immediately.

Important note1
Positioning the instrument
STOP
As can be seen from the fi gures, the handle can be set into dif-
ferent positions:
A and B = carrying
C = horizontal operating
D and E = operating at different angles
F = handle removal
T = shipping (handle unlocked)
Attention!
When changing the handle position, the instrument
must be placed so that it can not fall (e.g. placed
on a table). Then the handle locking knobs must be
simultaneously pulled outwards and rotated to the
STOP
required position. Without pulling the locking knobs
they will latch in into the next locking position.
Handle mounting/dismounting
The handle can be removed by pulling it out further, depending
on the instrument model in position B or F.

Safety

This instrument has been designed and tested in accordance
with IEC Publication 1010-1 (overvoltage category II, pollution
degree 2), Safety requirements for electrical equipment for
measurement, control, and laboratory use.
The CENELEC regulations EN 61010-1 correspond to this stan-
dard. It has left the factory in a safe condition. This instruction
manual contains important information and warnings that have
to be followed by the user to ensure safe operation and to retain
the instrument in a safe condition.
The case, chassis and all measuring terminals are connected
to the protective earth contact of the appliance inlet. The in-
strument operates according to Safety Class I (three conductor
power cord with protective earthing conductor and a plug with
earthing contact).
The mains/line plug must be inserted in a socket outlet provi-
ded with a protective earth contact. The protective action must

not be negated by the use of an extension cord without a pro-
tective conductor.
The mains/line plug must be inserted before connections are
made to measuring circuits.
The grounded accessible metal parts (case, sockets, jacks)
and the mains/line supply contacts (line/live, neutral) of the in-
strument have been tested against insulation breakdown with
2200 V .
DC
Under certain conditions, 50 Hz or 60 Hz hum voltages can oc-
cur in the measuring circuit due to the interconnection with
other mains/line powered equipment or instruments. This can
be avoided by using an isolation transformer (Safety Class II)
between the mains/line outlet and the power plug of the device
being investigated.
Most cathode ray tubes develop X-rays. However, the dose
equivalent rate falls far below the maximum permissible va-
lue of 36pA/kg (0.5mR/h).
Whenever it is likely that protection has been impaired, the in-
strument must be made inoperative and be secured against any
