resistance "standard"

Hi gang, OK, here's the missing criteria for my "standards":

  • costs less than 50$ cdn before shipping, used or new...

The idea is that anything with any accuracy at all is going to be so much beyond what I need that I won't waste time speccing them electrically. However, I do need to buy them, and 50$ is an amount I comfortable with.

For resistance, I think a 1K resistor will do nicely and cover calibrating any DMM or d'Arsonval meter thingy.

A Vishay (who else?) Y14531K00000T9L 1K00 0.01% 0.2ppm/C is going to be very good and costs 20$ new!

My question is, do I put this guy in a box with 4 banana plugs for force/sense connection?

Makes sense? Do I crimp or solder to the leads? I'd connect them directly to panel mount banana plugs and there you go.

Thoughts?

TIA!!!

Attach it to a Pomona dual banana plug, either the solder types or the screw-in kind.

Note that it's specified at 0.5" lead length, which is sort of weird for a PC mount part. Classic axial wirewounds were measured with 3/8" leads.

I have a few old L&N standard resistors, ebay mostly, that we've checked against our best DVMs when they are new, or just come back from the cal lab. They all seem to be mighty good.

I strongly recommend a 4 terminal connection at the specified distance for the sense leads. JL is ok but just does not "get" the standards lab viewpoint.
