I assumed it was something like that. The original use was probably for a large
laser printer and I believe there can be some rather high surface voltages
present. Why is there a vibrating sensor in the probe?
I cannot think of any reasonable use for it (and I have so much "stuff" tucked
away at home that I hesitate to add any more). I'll probably return it to the
trash bin.
Thanks,
Bill
