Never mind! I just realized I grabbed the wrong meter!

I wanted to calibrate my 3400a RMS voltmeter, but it doesn't match
any of the manuals available online. It is SN 1208A13887. On the
back of the meter the DC output is from a banana jack pair, and
there is provision for running the meter off +/- 35 to 55 volts.
It contains a single horizontal board (and a second small board -
probably an amplifier in a shielded enclosure behind the BNC
input), with no plug-in boards.
Does anyone have any information on this variation of the 3400A?
Thanks,
Gary Appel
