content: Finally scanned pdf's and attached,I sent in my master 732B to Keysight for a direct comparison to its JJ array. It's a fantastic deal, $1,000.00 cheaper than NIST. The output value was based on 217 readings with a total uncertainty of 20.5 nV. And for the $1,600.00 it charges, you also get the 1.018 output checked. Mine had an uncertainty of 15.2 nV.The output value is given to 10 digits. And the monitoring took 2 weeks. I have some previous cal points, so now I can estimate the output on a daily basis. After 3 years, my trending figure was within 0.3 ppm. So, I should be able to do better now.

content: The cal docs are still sitting in the scanner ADF. It won't work with linux. It's an Ethernet connected Xerox B215 MFP. When I figure it out,, I'll post the scans.

content: Working with Keysigut on purchasing laborarory services from it, proved d9fficult at first. Keysight has detailed and inflexible methods to serve its customers. It does not sell certain things to the general public, and the stqndards lab cal is one. I don't have a company website, domain, email qddress, Dunn and Bradstreet number and rating, company checking account, street address in a commercially zoned area, company phone #, or fax number; so Keysight wanted proof that my company name in my profile in my website account, was actually located at the corresponding address. .I sent as proof of company address, a photo of an envelope with the company name and address, which is my home address. It didn't fly. So Keysight made my company name my actual name, so I could order as a business according to Keysight's policies. Keysight is such a large company, with 0ver 100 locations, and thousands of products available worldwide, along with facilities to do service and repair, that unless you have experience dealing with it, it can take a long time..For the standards lab calibration aqainst the JJ array, there are at least 10 variations depending on the neeeds of the customer. i have traceability, anab logo, 17025 and Z540.

content: Hmmm. Just take a picture of the page with your phone. No one needs a real scan! (Just like in the 1980s cover the top secrety stuff before the photo is taken).Thanks,Randall

content: "This Zenner voltage standard"? I don't want to bethatguy, but for the fee they charge, I'd think they could have a 2nd person have a glance at the template, if not the actual certificate. I mean, that's the kind of error, the customercanidentify ...I wonder, whether the certificate comes with additional information on how the uncertainties are calculated.
