API very helpfully quoted $495.00 for a replacement model 302 meter. Thanks, but no thanks. After a month or so one came up for a reasonable price on ebay - not a perfect match, however, since it was a -100μA - 0 - +100μA meter, whereas I needed 0 - 100μA. But close enough.$I_m = \frac{V \cdot R_6}{R_D \cdot R_m + R_D \cdot R_6 + R_m \cdot R_6}$ text/html 2016-08-28T20:25:18+00:00 Anonymous (anonymous@undisclosed.example.com) https://kitsune-denshi.net/equipment:hp4145a?rev=1472415918&do=diff HP 4145A Semiconductor Parameter Analyzer The HP 4145A in action. Floppy disk imaging and duplication The 4145A boots from a 5.25“ floppy disk, which is also used to hold user data. The format of the disk is sufficiently unusual (or rather, antique) that modern PCs will likely struggle to read the disks. However, due to the age of the original disk (mine is from 1989) and the fact that without it, the 4145A is nothing more than a very effective door stop, I was really keen to read the disk … text/html 2017-06-10T14:02:20+00:00 Anonymous (anonymous@undisclosed.example.com) https://kitsune-denshi.net/equipment:start?rev=1497103340&do=diff Equipment text/html 2016-10-13T15:01:48+00:00 Anonymous (anonymous@undisclosed.example.com) https://kitsune-denshi.net/equipment:vp5610p?rev=1476370908&do=diff Panasonic VP-5610P Introduction The VP-5610P is a compact 100MHz, 3-channel, dual delayed time-base analogue oscilloscope.
