A couple of my DMMs require a 1VDC reference for calibration, and I'm sure I am not the only one who has a 10V ref but not a 1V ref. I see lots of posts about arbitrary divider networks, but surely there's a simple 'fixed' 10:1 divider which will minimize the load on a reference, not degrade the accuracy, and not require re-calibration? The best resistors I have in my lab are PRC "standards" (the MC-7) with 0.01% rated accuracy, so I recognize I may need to buy specially graded resistors for the build.
On a related note, is there anyone in the central Indiana area who might be able to measure my MC-7 and give me 5-digit or better values for the elements? I'd like to be able to at least compare my DMM ohms measurements with a little more accuracy than the marked values, and some testing I've done already hints to me that a couple of them are borderline.
