Like Chris, I bought a $10 kit from Banggood, same PCB & firmware (judging by the sisplay) as this one: http://www.ebay.com/itm/DIY-Kits-Capacitance-ESR-Inductance-Resistor-LC-Meter-Tester-NPN-PNP-Mosfet-M168-/181303499014 I put 3 clipleads on it - much more convenient than a restrictive in-line socket. A beercan-sized electrolytic's finger-thick terminals go into a DIL socket only with difficulty. It's not accurate to twenty decimals, but I'm just looking for 5 milliohms or fifty - which it does with aplomb. (Leaving $190 change on the wizard.) Ah, here's the kit I bought: https://www.banggood.com/86-Plastic-Shell-DIY-Meter-Tester-Kit-For-Capacitance-ESR-Inductance-p-956240.html?rmmds=search Erik ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
