SIMPLE EDDY OPERATION
- Pick up the probe and insert it into the reference sample. The probe should fit into the piece snugly, with the sides touching the threads, but without having to force the probe. If the fit is too tight or too sloppy, you will need to adjust the probe tension. To do this, locate the set screw on the probe body. Adjust it in or out depending on the direction you need to move the tension. Try the probe in the reference piece again. Once you have established proper fit, move on to step 2.
- Placing the probe into the reference sample, rotate it a full 360 degrees. The Simple Eddy should alarm on the pre-manufactured defect. It it does, you are ready to begin tank inspection. Go on to step 4. If the alarm does not sound, go to step 3.
- The sensitivity may be set too low. With the sensitivity switch on the left side of the unit, turn the sensitivity up to 4. Repeat the test on the reference sample. Keep increasing the sensitivity by one number until the alarm sounds when the probe passes the reference defect.
- You may need to readjust the probe tension for the tank to be tested. (All tanks have a manufacturing tolerance for the neck diameter and therefore vary somewhat.) Position the probe guide at its highest position. Insert the probe into the tank at the top of the threads. Make a complete revolution around the threads, being sure to maintain constant speed.
- Loosen the probe guide and drop it to the next notch. Tighten the screw on the guide and repeat the test. Continue the procedure until the entire thread area has been inspected. If there is a defect, the Simple Eddy will give both an audible and a visible alarm.
- If a defect is detected, note the depth and position of the defect to help you locate it visually. A set of calipers is useful for measuring the actual depth. Inspect the tank visually to DOT & CGA standards to confirm your findings.
- Eddy currents are not a replacement for visual inspection. They are only a tool to make it easier for you to spot any abnormalities. Visual inspection is the final indicator of whether a tank needs to be rejected.
