Ultrasonic CW generator U10006
Laser diode for Debye-Sears effect U10007
Instruction sheet
8/03 ALF
Ultrasound generator with accessories for the Debye-
Sears experiment and for demonstrating standing ul-
trasonic waves.
Safety instructions
Before switching on the ultrasound generator and ac-
cessories, carefully read the following instructions for
the sake of your safety and for the safety of the equip-
ment.
• The slits in the device are for ventilation and must
be kept clear to avoid overheating the equipment.
It is recommended that the device be placed on its
own stand (also included).
• Before switching on the device make sure that it is
adjusted to the mains voltage you intend to use.
Make sure that you keep within the operating speci-
fications.
• Never try to push objects through the slits in the
device since this could cause short circuits or elec-
tric shocks.
• Only use 3B's own ultrasound transducer with the
"PROBE" connection. Be careful, voltages may be
as high as 70 V.
• Do not use the ultrasound transducer for a lengthy
period without contact to fluids. Otherwise the
transducer may overheat and be destroyed.
• Do not turn on the U10007 laser diode if there are

people standing in the beam. This is a class II laser
with power < 1 mW. Do not look into the beam or
aim it at other people or animals.
• Beware: high-powered ultrasound! Do not use the
probe on people or animals.
