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.

Handling

To view the screen from the best angle, there are three different
STOP
positions (C, D, E) for setting up the instrument. If the instrument
is set down on the fl oor after being carried, the handle auto-
matically remains in the upright carrying position (A). In order
to place the instrument onto a horizontal surface, the handle
should be turned to the upper side of the instrument (C). For the
D position (10° inclination), the handle should be turned to the
opposite direction of the carrying position until it locks in place
automatically underneath the instrument. For the E position
(20° inclination), the handle should be pulled to release it from
the D position and swing backwards until it locks once more.
The handle may also be set to a position for horizontal carrying
by turning it to the upper side to lock in the B position. At the
same time, the instrument must be lifted, because otherwise
the handle will jump back.

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.

Subject to change without notice
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 provided
with a protective earth contact. The protective action must not
be negated by the use of an extension cord without a protective
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
instrument have been tested against insulation breakdown
with 2200 V .
DC
Under certain conditions, 50 Hz or 60 Hz hum voltages can
occur 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 value
of 36pA/kg (0.5mR/h).
Whenever it is likely that protection has been impaired, the
instrument must be made inoperative and be secured against
any unintended operation. The protection is likely to be impa-
ired if, for example, the instrument shows visible damage, fails
to perform the intended measurements, has been subjected to
prolonged storage under unfavourable conditions (e.g. in the
open or in moist environments), has been subject to severe
transport stress (e.g. in poor packaging).

Operating conditions

This instrument must be used only by qualifi ed experts who are
aware of the risks of electrical measurement. The instrument
is specifi ed for operation in industry, light industry, commercial
and residential environments.
Due to safety reasons the instrument must only be connected to
a properly installed power outlet, containing a protective earth
conductor. The protective earth connection must not be broken.
The power plug must be inserted in the power outlet while any
connection is made to the test device.
The instrument has been designed for indoor use. The per-
missible ambient temperature range during operation is
+10 °C (+50 °F) ... +40 °C (+104 °F). It may occasionally be
subjected to temperatures between +10 °C (+50 °F) and -10 °C
(+14°F) without degrading its safety. The permissible ambi-
ent temperature range for storage or transportation is 40 °C
(-40 °F) ... +70 °C (+158 °F). The maximum operating altitude is
up to 2200 m (non operating 15000 m). The maximum relative
humidity is up to 80%.
If condensed water exists in the instrument it should be accli-
matized before switching on. In some cases (e.g. extremely cold
instrument) two hours should be allowed before the instrument
is put into operation. The instrument should be kept in a clean
and dry room and must not be operated in explosive, corrosive,
dusty, or moist environments. The instrument can be operated
in any position, but the convection cooling must not be impaired.
The ventilation holes may not be covered. For continuous ope-
