T4D #72 - Splitting Ball Hairs...The HP / Agilent 3458A...4 ppm! HD

------------------------------ Click "Show more" ------------------------------------------- A tool I have wanted in my collection for quite a while...and did not think would be possible. I was very lucky to find an HP / Agilent 3458A in almost mint condition on eBay with original manuals unopened...and loads of test leads in original bags. This fine example of an 8.5 digit precision scientific bench multimeter has option 002 installed to give it 0.0004% (4 ppm) accuracy and is used in metrology labs around the world. Will I have any use for it....Mmmm... Measurement Capability 8-ppm 1 year dcV accuracy, optional 4-ppm 0.05 ppm dcV transfer accuracy Superior AC voltage measurements System Capability 100,000 readings per second at 4 1/2 digits Data sheet: http://cp.literature.agilent.com/litweb/pdf/5965-4971E.pdf ------------------------------------------------------------------------------------------------------ My website and forum:- http://www.mjlorton.com Donations and contributions:- http://www.mjlorton.com My techie channel MJLorton - Solar Power and Electronic Measurement Equipment - http://www.youtube.com/MJLorton My Techie Amazon Store: http://astore.amazon.com/m0711-20 My other channel VBlogMag - For almost any topic under the sun! - http://www.youtube.com/VBlogMag My VBlogMag Amazon Store: http://astore.amazon.com/vblogmag-20 ------------------------------------------------------------------------------------------------------ =================================================== Video sponsor, Pass Ltd - their websites: At checkout use the discount / promotion code "mjlorton" for 5% off. http://www.tester.co.uk/?cmid=QmhzQjcxYjVlc1E9&afid=bFcwbzliNzVDc289&ats=K2EyUjZNTDh3UTA9 - Test Equipment and Test-meter suppliers and http://www.calibrate.co.uk/?cmid=QmhzQjcxYjVlc1E9&afid=bFcwbzliNzVDc289&ats=S3Yxd2tOMjVISzA9 - Calibration and service of test equipment =================================================== $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Bitcoin (BTC) Donations: 1K7PeF55e7ssE7W3WVCoa7c4j2PHzy6ASv $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ ********************************************************************************** Music clip from PatternMusic by Richard Lawler www.PatternMusic.com (used under creative commons Attribution-ShareAlike Unported 3.0) http://creativecommons.org/licenses/by-sa/3.0/ **********************************************************************************
