Hello all, Does anyone remember the old Datron 4000 series calibration software, model 4101B ? Any thoughts on what it was like, what instruments it supported ? Anyone even have a copy I could try out ? My experience with their software is only the Portocal 2 using a 9100 calibrator. I found it was well setup for their own calibrators and references, but cumbersome to write new procedures. cheerio, ben
