Wow, RTFM indeed! Working correctly now. It may have been a bit more than that however.
The seller advertised this meter as broken, specifically that it wouldn't measure amperage on the high range. This being a new meter to me I believed it (as did other bidders apparently) allowing me to purchase it for under $100 US. My very cursory review seemed to confirm the issue and I didn't even attempt to manually change the range. Hours of probing and hand drawing a schematic I could find nothing wrong.
Tonight, after reading your posts, at first the high range didn't work. I continued to step through the ranges, up and down (internals relays clicking) and alas, it started to read!
I am a very happy new owner of this fine instrument. Thank you all for your help.
