I'm not in my workshop now. Tomorrow, I will check the suggested test points.
I am going to buy the U500 from an American seller that I once bought a 2465B, which I ended up selling to buy this 2467B that I like so much, it is a confiable supplier.
When I receive the U500, which should take at least 40 days, I will update this topic.
Chuck, I have no words to thank you.
You are a kind-hearted person.
Thank you very much.
