We also refer to a September 1993 analysis done by a working group of the IEC technical committee 87

and prepared by K. Beissner, as a rst supplement to IEC publication 1161.

The document includes analysis and discussion of the sources of error / measurement eects due to:

Balance system calibration.

Absorbing (or reecting) target suspension mechanisms.

Linearity of the balance system.

Extrapolation to the moment of switching the ultrasonic transducer (compensation for ringing and

thermal drift).

Target imperfections.

Absorbing (reecting) target geometry and nite target size.

Target misalignment.

Ultrasonic transducer misalignment.

Water temperature.

Ultrasonic attenuation and acoustic streaming.

Coupling or shielding foil properties.

Plane-wave assumption.

Environmental inuences.

Excitation voltage measurement.

Ultrasonic transducer temperature.

Eects due to nonlinear propagation and saturation loss.

The overall findings of the analysis give a rough Acoustic Power accuracy figure of +/- 10% for the

frequency range of 1 - 10 MHz.\

Training

The operator of this equipment must become thoroughly familiar with the correct use of the equipment

in order to optimize its performance and recognize possible malfunctions. It is recommended that all

users receive proper training before operation. Applications training is available through the Samsung
