You could acquire a Fluke 5450A and have it measured. These are quite
good, and have all the resistors you need.

Looking for a set of precision resistors for calibration purposes.
I need the following values to calibrate the ohms ranges on my meters:
100
1k
2k
10k
20k
100k
200k
1M
2M
10M
20M
The crucial factor isn't that they be exactly the values above, so I don't necessarily need 0.001% parts. Low TCR is important, and I will need to know that actual values to 10ppm or better.
I'm looking for suggestions on the best choice of parts and pricing? I believe the Vishay HZ series may fit the bill for the lower values but they may be rather expensive.
Regards,
David Partridge
