If there are 3 or 5 good coils, choose one and set the initial setting. Display the waveforms of every coil by pressing the start button. Make a visual check of each waveform, and you will be able to find your best coil. (Please refer to our manual for the initial setting.)
＊ If there are 30 good coils

1. Choose one coil.
2. Store the waveform. (Set the value 10 – 20% for AREA, DIF-AREA)
3. Test all 30 coils and sort out 10 coils with DIF-AREA values that are very close.
4. Calculate the average of the 10 DIF-AREA values and choose one coil with the value that is the closest to the average, as a tentative master coil.
5. Store the waveform
6. Test the 10 coils and calculate the average of the AREA value.
7. The coil with the AREA value that is the closest to the average, will be the master coil.
