Error analysis
Errors may arise
• on the plug connections
• on the ultrasonic transducer
• on the probes
• on the HF generator
The device is robustly constructed and designed for a high level of reliability. Nevertheless,
the possibility of a malfunction due to a defective component can never be fully discounted.
Mechanical defects of the HF connector sockets, the plug connectors, the ultrasonic transducer,
etc., are possible as a result of frequent use or even incorrect handling, e.g. by dropping them.
