ESR meter

Howdy folks , I am looking for a ESR meter , is there any suggestion ? thanks a lot

Pay attention to the test voltage when you are shopping for a ESR meter.  I see that some brand-name LCR/ESR meters in the market have test voltage above 0.7V which may turn on nearby transistors and hence cannot be used in-circuit.  Some DIY designs uses test voltage as low as 0.2V to avoid this problem and hence can measure ESR without soldering the capacitors off the board.

    希望買還是diy?

買 好D diy 又要煩個case 而且見無咩廠ESR meter ,上網搵到既都係DIY野多..... ,例如fluke又好似無出 ? <-我搵唔到,同埋準度差就無意思(唔係一定要exact , 就算有偏差都希望穩定。因為見過D次次量同一粒個值都有一段距離 比較唔到大細就無用)

有埋殼....但可能需要再校準下先準
自從我買左TH2822A 之後已經冇再用佢... 你岩用可以轉讓給你...
