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 clas-
sification 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,
provided it is used correctly. However, there is no
guarantee of safety if the equipment is used in an
improper 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 visi-
ble damage, switch off the equipment imme-
diately and secure it against any inadvertent
use.
The instrument may only be connected to the
mains via a socket that has an earth connec-
tion.
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 tem-
peratures of up to 300° C during operation.
Set up the heating chamber on a heat-re-
sistant surface.
When the heating chamber is in operation, do
not attempt to touch or move the apparatus.
Only move or transport the equipment by us-
ing the insulated handle.
Allow the apparatus to cool before disman-
tling 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.
