Yes, mea culpa thanks to TC for providing the meters!
Your generator remains impressive, early in this thread Meter Junkie shows the Fluke 101 using an industrial quality one which is in $5k range, to start, I think the video shows a MegaPulse by Compliance West.
For the rest of us, one can do limited tests using much easier to access and afford kV sources like a hipot tester or an electrophoretic supply.
Given your generator, setup, and interest, keep on testing!
An idea, you could show how good older branded meters are, or not, on their impulse resistance. There are many pre-CAT and older CAT rated meters sold on Ebay.
Fluke 23, 25, 77, 8021, first generator 80s series, HP and Tektronix DMMs, Craftsman, Micronta, Beckman Industrial etc., as well as Japanese meters from the golden era such as Hioki, Sanwa, Yokogawa [ that were made in Japan.]
Also you can extend your tests to dielectric withstand of the chassis to the PCB, particularly in older meters, which could have deteriorated over time.
Thanks and glad your enjoying them. We can't forget about 5KY's contributions as well! Big thanks for giving me the opportunity to see just how much a Fluke 107 can take!!
