[null and void]

Buy a big bunch of 10K resistors and cull for one at that value.

Hint, control the temperature, as that will change the measured value.

Hint 2, use kelvin contacts (four leads - two to drive the test current, two to measure the voltage drop) to avoid contact resistance problems.

Or buy a 7K carbon resistor and a jeweler's file, measure the resistor and start filing a notch in it until the value rises to 9.4115K. Protect the cut with shellac or nail polish...

Hey, very good advice, except how long will it take to accomplish the task? I don't expect answer, because we all know it is not practical since it requires about a .005 per cent precision.
