6.2.5.1 Insert probe in defect free area of standard and press auto balance.

6.2.5.2 press in channel I button, turn up intensity, press in store buttons on MII 12 display and set V/DIV on 1.

All. other buttons must be out.

6.2.5.3 Check phase of ICO: thru wall hole signal on MIZ 12 display as probe is pulled thru standard.

If 100%

hole does not go down and to the right wnen probe is pulled thru standard and pr:be motion is not hori: ental, phase can be rotated by phase controls.

Estimate the phase angle error and make that direct change using phase controls. Re-check phase to make sur*.

1 defect signals go down first and prebe motion is herfrontal.

Continue this procedure until phase is correct.

6.2.6 Channel 2 Calibration procedure.

6.2.6.1 Insert probe in defect free area cf standard (auto balance does not need to be pressed as probe is balanced in all frequencies.

Hewever, if any gain is changed probe must be re-balanced).

7.2.7 Calibration standard identification.

7.2.8 Operator's name, certifi, cation level and company affiliation.

7.2.9 Probe size and model nunter.

7.3 Before the scan is made on each tube, the tube number will be recorded on the sagnetic tape and strip chart.

7.4 ' During the scan, the operator will monitor channels 1, 2, 3, 4 and the upper six on the MII 12 display to datamine that the equipment is operating properly and calibration has not changed.

In addition, the operator will sonitor the strip chart recorders for proper signals.

De tape recorder will pass thru signals to ths' strip chart racercars without the tape being recorded.

Therefore, the signals on the 2 strip chart recorders are. set up so one signal on each strip chart mcorder is coming directly from the MIZ 12 and the other signal is coming directly from the tape recorder.

If the tape recorder is recording, the 2 signals on each strip chart will be slightly displaced from each other.

This must be checked continuously as this is the only assurange you have that the tape recorder is recording.

7.5 The operator will initial each tube examined on the data sheet after the tube is scanned.

7.6 The probe speed during the scan will not exceed 70 feet per minute.

7.7 The nusber of tubes inspected, the length inspected and the frecuency of inspection will be datamined by the NRC Regulatory Guide 1.83 and specific customer requirements.

7.8 Examination of tubes at additional frequencies may be perfonned to evaluate possible discontinuity indications.

8.0 QATA INTERPRETATION 8.1 Data interpretation will be nude using infomation front the initial calibration of the 400 kHz data. The data interpretar may use the additional infomation from the multifrequency signal mixing as an aid in intarpreting the 400 kHz data.

T 8.2 Ali tubes with defect signals which Indicata defects 20t enru well or greater will be reported on data sheets, with the exception of s

defects above US + 20.

These defects fil be disregarded as they will be above new roll area.

2.6 Calibration Standard 2.6.1 The calibration standard will be machined for the same alloy and. -

tube size as the antarial under test.

2.6.1.1 For defect calibration there vill be four (4) circum-farential cuts.005" wide x.250" long approximately 40% depth spaced 900 apart. These cuts will be on the outside diameter and inside diameter of the tube.

2.6.1.2 For calibration verification there will be five (5) circumferential cuts.015" wide 3600 around the tube i

with the following appr minate depths; 100%, 80%, 60%,

40% and 20% through wall from the outside diameter of the I
