content: Hello!Could anyone of you, please, help with sharing instructions set (commands) for the Solartron 70755 GPIB unit? I am having the Solartron 70755 GPIB adapter, but no basic commands for controlling this unit.The best thing would be an electronic copy or paper original manual for this unit labeled "70755 Interface Operating Manual", Part No. 7075 0012.Thank You for any hints!Karel

content: Dear tggzzz!You are very kind!!! Thank You for uploading!!! The scans look very nicely! However, this manual is rather providing the service information, what is also very welcomed, but unfortunately no operator's one. Wouldn't You have also the GPIB instruction set for the 70755 unit? Or, wouldn't you know anybody, who could have?With many thanks!Karel

content: Yes but I'd rather use the original GPIB interface as part of my system all I need is the command set really.

content: while i understandare you related to DIYaudio forums by any chance ? there was search for this document and no news since 2012 ? this one seems unobtainable at some point ?7075 SK1 protokoll.txt explain a few things on that project, but this project may be your only chance ...as other suggested maybe some 7081 or nearest models may help to regroup gpib commands and try them on the 7075 ...good luck

content: I'm not from DIYaudio forums It seems a lot of people have searched for it over the years so you're probably right that it's unobtainable.And thanks for telling me about 7075 SK1 protokoll.txt I hadn't seen it before all.I did just find this posthttps://www.eevblog.com/forum/testgear/solartron-7075-digital-voltmeter-gpib-commands/which details the the mode, integration time and function commands.If I get my hands on it I'll do some trial and error to get the range commands.The 7075 has barely any functions anyway (no programs or anything like that) so with the range commands that's pretty much it.

content: If anybody wants to try out the GPIB commands of the Solartron 7061/71/81 series without the hassle of programming them himself, these instruments are supported by the freeware version of the program SweepMe (sweep-me.net)

content: Just thought I’d post it here since no one else seems to have it. Heinz (TheHWcave) has scanned a copy of the solartron 70755 operating manual so thanks very much to him( I did have to compress it slightly to attach it but I think it still looks fine)

Each page has a cleaned up tiff image, mostly 20kB-200kB in size.My understanding is that djvu also compresses across pages. Given that a highly compressed "e" will look the same on many pages, perhaps it isn't surprising that a factor of 2 can be achieved.
