Or point me towards where I can download one? All costs re-imbursed. Regards Robin -- Robin Birch Robin, I have bunches of HP manuals, at: . For the 1740A, it loos like all I have is the operator's guides, not a service manual. I think ONE of the ones that I have might also be downloadable from agilent.com . Good luck!

I am interested in the manual if it is a service manual with a schematic. You say it is the same as the 3449 (typo?) Is it the same as the 3439 except for the sampe rate? If so I am interested. leave me an email or web address Thanks BL --- In hp_agilent_equipment@..., "Joseph Orgnero" <joseph@p...> wrote: Jorgen,same as the 3449 except for the sample rate, cost U$S 12.00 plusshipping.

Re: HP 3439A

Ripple is about 1.5v on the 150v supplies and about .5v on the 50v
supply. This site: has the calibration procedure for the 3439A which gave me some more good information. This site: mentions the 3440A which is very similar and their unit has the same symptoms: "The nixie tubes light up, but multiple segments are on simultaneously" so I am thinking this problem is common on these units. Thanks for the replies so far.

don't know if it will make you feel any better but I have a Fairchild Model
7000, 5 1/2 digit Nixie tube?DMM? and I use it all the time.?
Works perfect.? I also have a Systron Donner 6152A, 500 mHz Nixie freq.
counter and it also works perfect.? I love Nixies -no reading glasses
required!? The pinnacle of display technology, IMHO, ?was planar
gas.? LCD displays were the downfall of modern electronics- screw low power
consumption!?

Sorry
I can't help you with the schematic.? There are many vintage manual

HP 3439A

Hello All
I was just given an old HP 3439A Digital Voltmeter to play with. It has the 3443 High Gain/Auto Range plugin. The Nixie tubes light but display random digits. I have searched for a schematic and found nothing. Really, like others have said here before, its the challenge to see if I can get it functioning, so any info about it is appreciated. Thanks BL |

Re: 3455, 3456, &3457 multimeters

That completes the continuum for me, then!!!! Very
cool. I have a Fluke 8050A, a benchtop 4.5 digit DMM with battery option. It's now 20 years old. I have never calibrated it. I take it to work once per year, and check it against an HP 3458A (8 1/2 digit calibration standard) and it's always right on, down to the last digit of the Fluke. On eBay, they're about $50. My question, though, is what are the "bargain of the century" DMMs that are HP-IB controllable? Or serial, or USB or....? The 34401A is too steep for me, given that I probably want several remotable DMMs. 73, Dave W8NF === In reply to === From: "John Miles" <jmiles@...> Subject: RE: 3455, 3456 & 3457 multimeters A friend in town (W7TOM) just bought an HP 3478A, and we were both very favorably impressed by it. I have a HP 34401A on my bench which I bought brand-new for $1K, and the 3478A is almost as good at 20% of the price. It has one less digit of resolution than the 34401A (5.5 instead of 6.5, either are more than sufficient for nearly any practical purpose and much more than any handheld can offer), and a couple fewer bells and whistles (dB, frequency...) that I don't use anyway. Calibration is simple, with no need to open the cabinet, and the manuals are excellent. Bob's 3478A showed an invalid calibration checksum on one DC voltage range, so we set it up against my 34401A and he was good to go. The other ranges were so close to the 34401A that no adjustment was warranted. Dealers sell the 3478A for around $300; the going eBay rate is $200 or less. These things are the T&M bargain of the century, IMHO. I wish I'd gone the 3478A route -- I could have gotten essentially the same meter for a lot less money.

The HP 3478 has one major drawback I think,I have a few HP3456As and have been pleased with them. The have a 1000 volt range and I think they can measure higher voltages than the HP 3478.

I have some HP test gear for sale, e.g. HP 3456A, HP 3455A, HP 3325A, HP power supplies, etc., for pickup only in Illinois. They are large and I don't want to have to pack them.

Re: 3455, 3456 & 3457 multimeters
A friend in town (W7TOM) just bought an HP 3478A, and we were both veryThe 3478A is certainly a nice meter, but I have a hard time getting my bench lighting right so LCDs are readable without too much light falling on the scopes. Too bad it doesn't have a backlit display. My personal favorite DMM is a Solartron 7060, but it's a lot larger than a 3478A. |
