1. Safety instructions
The apparatus conforms to the safety regulations for
electrical test, control and laboratory equipment as
specified in DIN EN 61010 Part 1. Its protection classifica-
tion is deemed to be class I. It is intended for use in dry
rooms suitable for electrical equipment or installations.
Safe operation of the equipment is guaranteed, pro-
vided it is used correctly. However, there is no guar-
antee of safety if the equipment is used in an im-
proper or careless manner. If it is deemed that the
equipment can no longer be operated without risk
(e.g. visible damage has occurred), the equipment
should be switched off immediately and secured
against any inadvertent use.
In schools and training institutions, operation of the
apparatus is to be responsibly supervised by trained
personnel.
• Before putting the equipment into operation, con-
firm it is compatible with the local mains voltage.
• Before setting up or starting any experiments,
check the apparatus for any damage.
• In the event of any malfunction/defect or visible
damage, switch off the equipment immediately
and secure it against any inadvertent use.
• The instrument may only be connected to the
mains via a socket that has an earth connection.
• Only trained electricians are permitted to open
up the apparatus’ housing.
Beware: Risk of burns! The viewing windows and the
walls of the heating chamber can reach tempera-
tures of up to 300° C during operation.
• Set up the heating chamber on a heat-resistant
surface.
• When the heating chamber is in operation, do
not attempt to touch or move the apparatus.
Only move or transport the equipment by using
the insulated handle.
• Allow the apparatus to cool before dismantling
the experiment.
Beware: There is always a risk that glass can break
and cause injury.
• Use all six knurled screws to affix the front plate
to the heating chamber.
• Do not subject the tube to any mechanical
stress. Do not put kinks in any connecting leads.
The Franck-Hertz tube contains mercury.
• If the glass breaks and mercury escapes, make
sure to observe safety regulations relating to the
handling of mercury.
