Info needed on Ballantine 3440A RF Millivoltmeter
« on: May 29, 2016, 09:35:22 pm »
Hello all,
I just purchased this 3440A RF multimeter complete with 2 sets of 50 ohm RF probes and two 100:1 50 ohm T adaptors.
After calibration from Ballantine back in September 1989 it has been in a box until last week when I pulled it out and plugged it in.
As far as I can tell it STILL WORKS and it looks brand new !
Doing a quick search for a user's manual yielded zip so hopefully someone out there might have one for this beauty ?

Ballentine appears to still be doing business.

radhaz: tnx for the quick reply ! I saw that but $100 is a bit way tooo far out of reach for me for just a manual

That is good news. Their manual pricing drove me to buying one on epay for my 323-07 meter.

i argued them down to 15, wanted 30. Plus 12 in shipping  :-//
That 12 in shipping confused me.

Was that for a paper copy or CD ?
