1.1.1 Intended use and area of application
The instrument is a portable general-purpose ultrasonic device.
The instrument is designed for searching, evaluation and localization of various discontinuities, defects and irregularities
in different objects made of metal and plastic.
The flaw detector allows generation, registration and recording of time realizations of pulse ultrasonic signals in its memory.
A color TFT display indicates the ultrasonic signals in form of A-Scans. The instrument provides both manual and automatic
measurement of time intervals, signal amplitudes as well as automatic determination of locations of the flaws.
1.1.2 Operating conditions
The instrument is designed to operate under the following conditions:
- temperature from - 30 to +55 ˚С;
- relative air humidity up to 95 % at + 35 ˚С upper temperature limit.

1.3.1 Design
The flaw detector includes an electronic unit to which the removable piezoelectric transducers (PTs) are connected via cables.
1.3 DESIGN AND OPERATION
Figure 1
11.3.1.1 Electronic unit
The electronic unit provides the generation of electrical impulses for excitation of the piezoelectric transducer,
amplification of the signals received from the PT. The electronic unit generates and processes measurement results
and provides their display in digitalized form, records data into nonvolatile instrument’s memory and allows their
transfer to the external PC.
The external design of the electronic unit is presented in the Figure 1.
The instrument is controlled by means of a membrane keyboard. The display and LEDs on the housing of the
device indicate the signals, measurement results and state of the instrument.
The PT is connected via coaxial cables (included in the delivery kit) by means of the LEMO
connectors.
The instrument is powered from the battery unit or a power adaptor included in the de-
livery kit.
1.3.1.2 Power adapter
The power adapter provides external power supply of the instrument and charging of the
battery unit from AC mains (15 V).
The charge time depends on the depletion of the accumulator unit; it can last up to 3
hours. The instrument can be operated during charging of the battery.
Always connect the cable of the power adapter to the electronic unit first, then connect
the network cable to the power adapter, and then connect the network cable to the AC mains
to prevent damage of the instrument.

1.3.2 Transducers
The flaw detector is designed to operate with single crystal and double-crystal PTs with operating frequencies from 0.5
to 15.0 MHz.
Two cable types are used with the instrument depending on the type of the transducer. Hence, two connection ways of
the PT exist:
Single crystal transducers (S type) shall be connected via LEMO-LEMO single cable to the unmarked connector (Figure 2).
Double-crystal transducers (D type) shall be connected via LEMO-LEMO double cable. The connector marked with a red
dot is used for connection of the transmitting piezoelectric element, and the unmarked connector for the receiving piezoelectric
element (Figure 3).
1.3.3 Interface
The instrument has an intuitive interface. The content-addressable icon menu in different modes, names and schematic
indications of the keys allow quick understanding of instrument operation.
The display continuously indicates all information required for on-line inspection.
The library of configurations facilitates work with the instrument. The user can assign a unique name to each configuration.
Consequently, the user can adjust the instrument to be operated under different conditions and for inspection of various objects
in a good time. Then the only recourse the user has is to select the configuration from the list.
All settings of the device shall be saved if the instrument is switched off, stored without the battery unit or if the battery
unit goes dead.
1.3.4 Operation modes
The main operation modes of the instrument are as follows: FLAW DETECTOR, provided additionally are STOP and SETTINGS modes.
In the operating mode the instrument generates the sounding impulses, amplifies the received echo signals and displays
them, as well as performs measurements.
In the STOP mode the user can stop (freeze) the signal realizations (snapshots) displayed on the screen, record them into

1.3.5 Display of information on the screen
A color TFT display (640х480) indicates the measurement results and service information required to control the instrument.
The workspace of the screen is divided into several functional areas in each mode. In the Figure 4 the display in the FLAW
DETECTOR operating mode is shown.
