On the front panel of the unit there is the symbol of the instrument
with the trademark of the manufacturer. On the back panel, under
the battery cover there is device's serial number.
Information processing unit and probes are stored in a case that
would prevent them being damaged during transport.
6. Principle of operation
6.1. Operation options
6.1.1. The device operation is based on the measurement of the
ultrasonic pulse in the material product from the transmitter to the
receiver. Ultrasonic velocity is calculated by dividing the distance
between transmitter and receiver measured at the time.
6.1.2. The spreading velocity of the ultrasonic waves in the material
depends on its density and elasticity, the presence of defects
(cracks and voids), which determine the strength and quality.
Consequently, sounding elements of products, designs and
constructions can obtain information on:

- strength and uniformity;
- modulus of elasticity and density;
- the presence of defects and their location;
- form of A signal.
6.1.3. There are options are sounding with the lubricated and dry
contact (protectors, conical nozzle).
6.1.4. The device visualizing received ultrasonic waves (with flaw
detection mode), has built-in digital filters, improving the ratio of
"signal to noise ratio." Flaw detection mode allows you to view the
signals on the display (in the given time scale and intensification),
manually set the cursor to the position of the reference mark for the
first entry. The user can manually change the intensification
measurement channel and shift the axis of time for review and
analysis A signals (signals of the first entry and the enveloping).
