1. Safety instructions
The device conforms to the safety regulations for
electrical measuring, control, monitoring and labo-
ratory equipment, as specified under DIN EN 61010,
section 1, and is designed to be classified as protec-
tion class I equipment. It is intended for operation
in a dry environment as this is suitable for the op-
eration of electrical equipment and systems.
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 oc-
curred), the equipment should be switched off im-
mediately and secured against any unintended use.
In schools and other educational institutions, the
operation of the function generator must be super-
vised by qualified personnel.
• Before putting the function generator into op-
eration, confirm that the specifications printed
on the rear side of the housing are compatible
with the local mains voltage.
• Before putting the function generator into op-
eration, check the housing for any damage. In
the event of any malfunction/operational defect
or visible damage, switch off the unit immedi-
ately and secure it from unintentional use.
• The instrument may only be connected to the
mains via a socket that has an earth connection.
• Before making any connections, check the ex-
periment leads for damaged insulation and ex-
posed wires.
• Never cover the air vents and heat sink at the
rear of the housing. These are necessary in or-
der to ensure sufficient circulation of air re-
quired for cooling the components inside the
equipment.
• The equipment may only be opened/repaired
by qualified and trained personnel.
2. Description
This high-power function generator is intended for
conducting experiments on the topics of harmonic
oscillation, acoustics, ultrasonics and magnetic
induction, concentrating mainly on the low-
frequency range. Frequency can be adjusted over
seven decades ranging from 10 mHz to 100 kHz.
The equipment involves an external AM and FM
(sweep) modulating function generator with power
amplification and digital frequency display showing
values and units. It can be used as a function gen-
erator, DC voltage source or power amplifier and
provides alternative operating modes such that it
can be used as a voltage or a current source with a
power output of 50 watts. Any overload of the am-
plifier due to the setting of the offset voltage or
excessive input voltage is shown on the display. The
outputs are protected against overloading by elec-
tronic protection circuitry.
Function generator U8533510-115 is designed for a
mains voltage of 115 V (±10 %) while U8533510-230
operates with 230 V (±10 %).
