The local surplus guy has at least three different differential meters that have been collecting dust for decades. I have borrowed two of them (so far).
The first one is a Fluke 893A and is solid state. Although it appears to work, it fails the very first of the performance tests. Now that I have a full manual, I'm going to look at this a bit closer. The second one is a Fluke 803B (I think. There is no label on it). It has tubes. I am slowly bringing it up on a variac before messing with it. I plan to open it up later and take a good look. I'm not sure what the third model is, but it looks like it may be an even older Fluke. It is on a high shelf and I haven't gone over there to lift it down yet. I'll probably do that later this week. At the moment, I'm just playing around with this gear and learning a few things. In the long run, are these things worth having?
