[volt-nuts] Precision resistors

[Ludger.Lenzen at gmx.de]

How about a Fluke 5450A Resistance Standard. I have one and fully satisfied regaring precision, drift and tempco. Covers all your values.
One is actually offered for $600 or offer with calibration, means less than $60 per value.

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
