16 Adjustment of the generators
An adjustment of frequencies is required after replacement of
the following components:
• tank with complete mounted transducer system
• transducer disks
• complete generator print
• transistors
• coils and output transformer
Wrong adjustment can destroy the generator and the
transducer disks.
For the measuring you need the following tools:
Required measuring
tools
• adjustable interrupting transformer
• wattmeter
• 2-channel oscilloscope
• 2 probes (1:1 and/or 1:10)
• mains interrupting transformer
For further description of the measuring tools see section 1.5.
Carefully read and observe the following safety warnings before
you start the adjustment of the generator!
Risk of electrocution.
Live parts inside the unit. Even in the switched-off unit there are
several components charged with electricity!
In order to prevent damage on persons and equipment, the
mains-driven measuring instruments and the open unit must be
connected via a mains interrupting transformer.
CAUTION
An open generator output can damage the electronics.
The generator print must be operated with connected
transducer system only.
NOTE
Risk of damage to the electronics by thermic overload
Operate the generator only with the transistors fixed to the
relevant cooling body (bottom plate etc.)
