OT - Need Help/Info For Keithley 155 Null Detector/Microvoltmeter
Mike Harmon
Hi Group,
I have a Keithley 155 Null Detector/Microvoltmeter which has some problems. I downloaded a manual from the Keithley web site, but when I looked for the schematic, I couldn't find it. Section 5 of the manual says the schematic is shown in Figure 5-3, but it's not there in the manual provided on Keithley's download site. I contacted Keithley about the omission and was told by John Sobola that all schematics had been removed from downloadable manuals on Keithley's site, as well as the instruction manuals for all current Keithley products. When I asked if he could send me one, he said I had to provide the company with a bunch of info as to who I was, what company I represented, what I did, and why I wanted a schematic. I sent him the info he requested (it was for my own personal use), but did not receive a reply from him for a couple of weeks. I wrote him back and asked him if he needed more info, and he finally told me that the company had decided not to make the schematics available. I suspect if I had lied and told him that I was the engineering director of Company X and we had $750,000 worth of Keithley gear in the lab, he would have overnighted the schematic to me. I have no idea as to why they would have done this, but it pretty much makes the downloadable manuals useless without the schematic. As it stands right now, I have a sweet little meter sitting on my bench which is completely brain-dead! Please let me know (OFFLINE) if you can help me out. I don't want to start another flame war. Thanks, Mike, WB0LDJ |

Greetings,
Thanks to good advice from this forum, my 895 printer is working great on black and white. The red color works on both of my C1823 color cartridges. Blue works on one. Neither works with the yellow. I have tried cleaning the jets with 92% isopropal alcohol without result. Suggestions? Jerry |

However, I do need to find out how to automatically add manuals in a safe way, since I cant devote too much time for it. I'm guessing that I would need some help from you people as moderators, in order to allow manuals to be published for download. Any suggestions would be appreciated. As some of you probably are aware of, I do have a repository for NAK gear and some test equipment as well. I'm currently on SERVAGE with quite a lot of disk space and bandwidth available. With best regards Tomas Larsson Sweden my main work-site, sorry currently only in Swedish, working with refrigeration. My citroen XM repository, in Swedish. for downloads etc. ftp://ftp.servage.net for uploads use "naks" as both password and username. Or you can use the free www.yousendit.com service.

HP boatanchor help
Hi all,
I am in the process of restoring a huge HP 524B counter. 100 tubes and about 100 lbs makes it qualify in spades as a boatanchor! After looking for many years I recently found one to replace my butchered unit which was beyond restoration. My (slight) problem is that the behemoth I have is a later model than the manual I have. The main difference relates to the readout system for the fastest two decades, which are centre-zero meters calibrated 0-9. The older manual shows the staircase voltage for these meters derived from a resistor network driven from the plates of the counter flip flop tubes. The actual unit I have has a plug in unit labelled "524B-65A staircase amplifier" with four 12AX7 tubes. Does anyone have any info on this change? I suspect the amplifier was added to reduce loading on the counters which were already pushed to the limit of what you could do with vacuum tubes. The 10 MHz decade counter is a very complex bit of circuitry. Thanks, and happy holidays, Morris |

Hello everyone,
I'm pursuing a project to post many of the older HP Application Notes onto the Agilent website. I could really use your help!

This is a chance for you to influence which ANs get digitized for all customers. Please send your email by 5 January. To force you to prioritize :-) please list no more than 20. You can send me the AN #, Title or Description. Thanks, Mike Kawasaki mike_kawasaki@... |

Re: data aquisition switch
freo12000
Hello Paul,
You're very welcome. The 34970A is a nice system. As mentioned, I have a number of functional 3497A's, a couple of untested 3498A extenders and a large amount of relevant hard copy documentation, along with a various cards which have been tested and are known to be functional. I am happy to pass on the IBasic code I wrote to test the cards and the test results, and was actually contemplating offering it all on the big auction sometime, but it's a lot of effort for potentially little return, so if you ar any others in the group wish to take the 3497A path, I am happy to help at minimum cost. We obtained the whole lot for a song from a closed local R&D project and don't expect a large return for it. Regards, Ron Wilkinson ==== Ron and Davidand manuals etc.being on my bench. Its very flexible and easy to use but but its hire period |

Re: data aquisition switch

Ron and David
Thank you for the informative answers, I can start to trawl the info and manuals etc. I currently have the use of a 34970a and I've become used to it being on my bench. Its very flexible and easy to use but but its hire period finishes shortly. I will have to buy something to replace it but it really needs to be an earlier unit to make it affordable for home use. Anyway, thanks again, lots to go on now. Regards Paul -- 73 de Paul GW8IZR IO73TI |
