--- Quote from: The Electrician on January 05, 2018, 03:48:37 am ---The project you are planning to build has a couple of banana plugs on the project box connect with ordinary wires inside the box. Those wires probably have a resistance of several milliohms which will add to the measured ESR unless some method is provided for compensating. Using a 4 wire connection is the standard way of solving the problem of lead resistance. --- End quote --- All my ESR meters are made in the form of tweezers. In this circuit, the reduction of the resistance of the measuring probes will be solved in a similar way. |

I think this topic is nearest my question. Just thinking what is best budget choice to measure ONLY esr. Not need that transistor, resistor, etc testers. Of course if you guys are that thinkings that price 8-15 transitors/resistor/capacitor/esr testers are accurate enough well i happy take links to good one :) I thinking that just ESR meters are very much accurate and better reliable result, than that 8dollars cheap "multi" testers. Maybe i be just wrong. Measuring directly on circuit is very big positive thing. Can be kit or ready. Price point is about 30-100dollars. And if possible europe shops are better because customs, taxes, postages etc :) I know only Black one what Eevblog Dave use if i remember right something: Dick Smith Electronics but i think that not get anymore and price going with customs, taxes and postages quite high. This is only one what i finded: http://clientes.netvisao.pt/greenpal/evb1.htm This looks quite good and get kit version too. Seems better than china clones on ebay, but anyone know is that ones ok? Not any information is that crash, bad, good or something else :P I use that meter my hobby. Normally measuring normal 10-35v 100-1000uf elkos and 230-400v 2-40uf elkos. Different repair projects etc. |

on my repository (web link below in my signature) you have a lot of esr meters to build or buy just choose the one you want. the JayDaddy 5 transistors one, or the old poptronix are simple to build, and give accurate results. |

The PCB is already drawn. This is an experimental option. Then I will do as a tweezer. :) |
