David, The difference between the 335 A or D model I don't recall off the top of my head specifically, but they were improvements. I would probably take the D but really either one is good, assuming, of course, they are working.
You might want to consider getting both of them. They can handle being 1000 volts above ground. So with two you have a calibrated DC voltage up to 2000 volts. You still need a good null meter. While the 335's null meter is OK, it does not hold a candle to the Fluke 845 when it comes to isolation. Are you just gathering this stuff for your own use as a hobbyist or are you intending to get into some commercial concern ? Bill....WB6BNQ "David C.
