Re: [volt-nuts] Fw: Datron 1281 / 1271 secret GPIB cmds for CALRAM-Readout
PeLuLe, I am currently working on two 1281's. If you have anything you would like me to try, let me know. I am certain my cal constants are not good on one of them. The battery was just changed a few days ago and it appears to be the original from '87. I also had some intermittent NVRAM errors. Replacing caps worked for the first 1281 and cleared the DCV 2182 error. The project is a WIP and everything is being documented on xDevs. Also, please post your FW versions. Both of mine are at different revs and I would like to know the different versions from Datron/Wavetek On Sun, Feb 7, 2016 at 2:33 PM, wrote: > > > > Gesendet: Sonntag, 07.
