Abstract

The equipment used in standardization must be adjusted in order that both the receiver amplifier and video display are linear over the range of distance and flaw size to be used. The failure to do that would result in different block-to-block response ratios because of the measurements depending on the scope reading or attenuator setting. In this paper, using two sets of steel reference blocks (area-amplitude and distance-amplitude) to modified method to verify the linearity of the system of instruments used in the ultrasonic inspection. This method depends on the response from reference blocks with different hole diameters at constant gain and ratio between the figures slope at different gains. The linearity of the ultrasonic instruments can be measured with high precision. The results can be used effectively for determining resolution and sensitivity capabilities.
