FIELD: nondestructive test of strength of structures. SUBSTANCE: device ensures simplicity and high reliability owing to possibility of setting by program of practically any function of analog-to-digital conversion and of detection thresholds which makes it possible to adapt device to various objects of test. Multichannel device easily increases or decreases number of channels depending on objectives of test. Given device does not require any expensive hardware ( fast analog-to-digital converters, specialized imported microcircuits, etc ). EFFECT: simplicity and high reliability of device. 2 dwg
