So I know which end is hot. :-)
I bought 2 of the ones with the clear case. Figured I would probably blow one or both with the dielectric absorbtion of the typical aged 'lytic cap. One doesn't always remember to short circuit them before hooking up the probes, then remove the short. Its very good practice. > .ebay.com/itm/Assembled-GM328-Transistor-Tester-Diode-Cap-ESR-LCR-Volt >-Freq-Meter-PWM-Signal > <http://www.ebay.com/itm/Assembled-GM328-Transistor-Tester-Diode-Cap-E >SR-LCR-Volt-Freq-Meter-PWM-Signal-/182257972044> > > > > > > On Sat, Aug 12, 2017 at 10:00 PM, Erik Christiansen > <dva...@internode.on.net > > > wrote: > > > > On 12.08.17 15:18, Gene Heskett wrote: > > > A gismo called a Capacitor Wizard, around $200 from a guy in > > > Kansas City does the definitive such test, measuring the > > > equivalelent series resistance, aka ESR, and any capacitor that > > > reads over 2 ohms ought to be replaced. > > > > 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-/18130349901 > >4 > > > > I put 3 clipleads on it - much more convenient than a restrictive > > in-line socket.
