I set the voltage one at a time, but all bundled into the same Forth
word.
Wht would be *really* helpful is a command log (with responses) for
some time before the read, at least through the beginning of the
exposure and perhaps through the previous one as well.
I am at the Rio meeting and going directly to the airport tonight,
so will ask for help in the data retrieval.
This would be an ideal use for the "give me a complete log" archiver
query tool.
