General Information; Symbols; Use Of Tilt Handle; Safety - Hameg HM5012-2 Manual

Important hints
Immediately after unpacking, the instrument should be checked
for mechanical damage and loose parts in the interior. If there is
transport damage, the supplier must be informed immediately.
The instrument must then not be put into operation.

Use of tilt handle

To view the screen from the best angle, there are three different
positions (C, D, E) for setting up the instrument. If the instrument
is set down on the floor after being carried, the handle
automatically 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 standard. 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 instrument
operates according to Safety Class I (three conductor power cord
Subject to change without notice
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 2200V DC.
Under certain conditions, 50Hz or 60Hz 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 qualified experts who are
aware of the risks of electrical measurement. The instrument is
specified 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 permissible
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 ambient temperature range for storage
or transportation is 40°C (-40°F) ... +70°C (+158°F). The maximum
operating altitude is up to 2200m (non operating 15000m). The
maximum relative humidity is up to 80%.
If condensed water exists in the instrument it should be acclima-
tized 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
operation the instrument should be used in the horizontal position,
preferably tilted upwards, resting on the tilt handle.
