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.
