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
