Re: [volt-nuts] HP-3455A calibration

I did it time ago. Warmed up ~3 hours / Measure value with my 3548A. Next trimmed to mid of trimmable range (pot to center). Than trimmed (by shorting step by step) as close as possible to 10.000V. /PeLuLe > Gesendet: Sonntag, 19. November 2017 um 06:51 Uhr > Von: "Jeremy Nichols"

The pictures show error 9005, means "Serial Interface Error". This is the typical error, if the Analog-Board is not installed.   BR Ludger     Gesendet: Donnerstag, 22. Oktober 2015 um 15:32 Uhr Von: "Electronics and Books via volt-nuts" An: "Discussion of precise voltage

I had the same issue in the beginning (bad online reading with embedded PDF Reader). Thus I downloaded the ZIP package and had no issues anymore. Thus it seems to be an issue of the online reader, not caused by the files. BR PeLuLe     Gesendet: Donnerstag, 25. Juni 2015 um 11:08 Uhr Von:

Hi Randy, I would be happy to go on with the modification (for the HP 419A). Will also rout a PCB - plan to use EAGLE (V6) or maybe Altium Designer 14 (not yet used to). Any information (ideas, sketches, notes, files...) is highly welcome. I don't have an account for upload either, thus simply

Re: [volt-nuts] Datron 1271 AC Option

Hi Greg, Yes, I am open to sell it. I guess, 350 EURO plus shipment cost is a fair price. It would come with the required cables, shielding plate and the srews to mount. I did a short function test in my 1281 and got plausible values. So I will give also a DOA guarantee with cash-back, if you

Re: [volt-nuts] Datron 1271 AC Option

I have one spare (Germany). The AC option is a board with shields and cables. Simple to plug-in and to mount at the bottom of the system. Same as for the current option board. The 1271/81 detects it when the function is activated. There is no special requirement or matched version, but for sure

[volt-nuts] Datron 1281 cal ram data backup

Note: I have also posted at EEVBLOG forum. In my Datron 1281 (8.5 digit) bench DMM it seems, some of the electrolytics haved aged and need to be replace. I like to save the CAL-RAM content for security before working on (A backup is a good idea anyhow, if the battery drops). Does anyone know

Re: [volt-nuts] Design Spark PCB Design Package

I had same experiance with DS, even it is free, it not quite professional to use. I checked several free available PCB programs. I would recommend KiCAD, but the free version of EAGLE and the free German program Target 3001 (actual v1.7) I can also recommend.   BR Ludger Lenzen Gesendet
