Hi, Has anyone used Tektronix Calibration services?  (https://www.tek.com/fastquote)I have to send in a Fluke 732B (Volt standard) and a 742A-10K (resistance standard). The quotes are about half what Fluke charges for Z540.1 calibration.I'm just wondering if anyone has had any experience with them and can make any recommendations. I have submitted the two RFQs for the two units above and what I am questioning is they labeled the 742A-10K quote as:--------------------------------------------------FLUKE 742A-10K RESISTOR; FIXED; STDRESISTOR, AIR;<0.005%; 1Ω - < 1MΩZ540.1 2-YEAR Syracuse(Rome), NewYork$226.17 -------------------------------------------------- The "STD RESISTOR, AIR; <0.005%; 1Ω - < 1MΩ" is in the description and I'm just wondering if that is a generic name for the service or if that is really what they are reporting back on my 742A-10K in their cal report?  <0.005% (50ppm) report for a resistor spec'd to 4ppm over one year would be useless to me. Thanks,Victor Silva

I have used them for both. The standards were sent to their Rome, NY location. Price wise, the 732B 17025 cal is hard to beat if you can drop it at a local Tektronix office. I think Process Instruments is a good deal for resistance calibrations. The business is next door to Ohm-Labs and the owners are brothers. I have had good experiences with them and they can actually answer questions. Tektronix can be difficult to get specific questions answered.

Fluke has recently purchased a NIST PJVS (Josephson junction) which is accurate to about 12 digits. I believe Fluke is using the method and software developed by NIST using the PJVS to directly calibrate the 732B monitoring temperature and other parameters simultaneously. I would check with Fluke, but if that is how they are now doing Calibrations I would think it is worth the price. https://www.nist.gov/sri/standard-reference-instruments/sri-6000-series-programmable-josephson-voltage-standard-pjvs<https://www.nist.gov/news-events/news/2013/04/primary-voltage-standard-whole-world> Cheers; Tom Knox 303-554-0307 actast@hotmail.com "Peace is not the absence of violence, but the presence of Justice" Both MLK and Albert Einstein ________________________________ From: volt-nuts <volt-nuts-bounces@lists.febo.com> on behalf of Todd Micallef <tmicallef@gmail.com> Sent: Friday, August 9, 2019 3:37 PM To: Discussion of precise voltage measurement <volt-nuts@lists.febo.com> Cc: Victor Silva <daejon1@yahoo.com> Subject: Re: [volt-nuts] Recommendation for calibration services I have used them for both.
