Mike,
I found that page on rptrbldr also.
Its not much but better than nuthin.
Thanks for the bit of history. I didn't know that before.
I have one of the Helper millivoltmeters. It sure works well for me.
Sure are a lot for sale on Ebay without the probe. Fortunately I got one at a reasonable price with the probe.
Did you see that design for a homebuilt probe? Somewhere here on rptrbldr I think.
thanks again.
