Hello, Wangshuang. The change of color has been a progressing issue. It started with some very small spots of faint yellowish shadows at the top of the signal receiver. now the affected area (top of paddle) has clearly grown in size. Never I have smell fumes nor have stop collecting the signal, although the attenuation seem to have lessen if the factor is 10K as you pointed. I have only used the probe on COP coils, mainly two (2) wires coils. Will take pictures tomorrow to expand your understanding of my observation. Thanks for your help and interest.
