Chapter 1 Safety

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

X

Balance system calibration.

X

Absorbing (or reecting) target suspension mechanisms.

X

Linearity of the balance system.

X

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

and thermal drift).

X

Target imperfections.

X

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

X

Target misalignment.

X

Ultrasonic transducer misalignment.

X

Water temperature.

X

Ultrasonic attenuation and acoustic streaming.

X

Coupling or shielding foil properties.

X

Plane-wave assumption.

X

Environmental inuences.

X

Excitation voltage measurement.

X

Ultrasonic transducer temperature.

X

Eects due to nonlinear propagation and saturation loss.

The overall ndings of the analysis give a rough Acoustic Power accuracy gure of +/- 10% for the

frequency range of 1 - 10 MHz.

Training

The users of this ultrasound system must familiarize themselves with the ultrasound system to optimize

the performance of the device and to detect possible malfunctions. It is recommended that all users

receive proper training before using the device. You can receive training on the use of the product

from the Samsung Medison service department, or any of the customer support centers worldwide.
