h or 22 7 2.2 Calibration checks may be made using a conveniently portable test block such as the IIW in lieu of the basie :alibration block.
7 2.3 Should a check indicate a change in amplitude response greater than 20% (2 db) the tester shall be immediately recalibrated.
7.2.h Performance of the calibration check shall be indicated on the inspection report er chart record generated for each examina-tion.
7.3 Generction Of the Dintance Amplitude Curve For Angle Beam Testing Of Nuclear Piping and Components - Excluding the Reactor Pressure Vesse:,
7.3.1 The distance amplitude correction curve shall be constructed by plot'ing responses from the Basic Calibration Reflector.
The first plotted point is the response from the reflector at the nearest point. This response shall be obtained by posi-tioning the transducer for maximum return. The gain control is then set so that this response is 75 percent of full nereen.
Without further changing the gain, the search unit shall be placed similarly at other nodal positions and the indication response shall be marked on the tester screen, and its metal path (in microseconds) and amplitude marked on the DAC curve plot of Figure 2.
This point is the PRIMARY REFELENCE RESPONSE.
The tester sweep shall be adjusted to display 2-1/2 moden when-ever possible.
7.3.2 Connect the plotted points on the tester screen and on the DAC cut 7e plot with a smooth line to form the DISTANCE A!PLITUDE CORREC2 ION curve.
7.h Generation Of the Distance Amplitude Curve For St*
ght Beam Tesiing Of Piping and Component Welds - Excludin6 the Reactor Pressure Vessel 7.h.1 A bistance Amplitude Correction Curve is not required for material one inch or less in thickness.
7.h.2 For material over one inch thick a Distance Amplitude Corree-tion Curve may be constructed using the proper calibratien block (determined by Figure 1).
With the search unit positioned for maximum response from the basic calibration hole at 1/h T (see Figure h), set the signal amplitude to 50% of screen height.
This is the PRIMARY STRAIGHT BEAM REFERENCE RESPONSE.
Without changing the instruments cettings, cimilarly position the search units over the reference reflector at 3/h T.
Mark the amplitude and position of both points on the screen and on the DAC Curve plot on the Calibration Record Sheet.
