I would like to buy my own "off the shelf" set of resistors, capacitors and inductors (5-10 of each type) and send them out to be precision measured at a "typical" room temperature (recorded), the LC parts at
1kHz, to an accuracy of 0.1% or better (1000 ppm). I understand that long term component stability is an issue, especially with some types of capacitors. I'd probably go with a "base" of 1% metal film resistors, NPO ceramic, silver mica, and polypropylene caps, etc.Value ranges are approximately:
R: 8 to 500k Ohms (might not need over 100k) C: 10pF to 500uF (might add 1pF if can) L: 10uH to 8H
The purpose is to have my own references solely for my own use to field verify the accuracy some of my own test equipment without paying the kind of money typically needed with high end calibration standards. The company that does the measurement should have equipment that is NIST traceable. I know HP/Agilent made/makes some models of LCR meters that have 0.1% or better accuracy (e.g., HP 4274A, HP 4284A, $1K-10K).
Has anyone had any experience with this kind of thing, and/or can recommend a friendly lab that will perform such measurements at a low cost (say, < $100)?
Thanks in advance,
Mike Shell
