This MESR-100 V2 auto-ranging capacitor ESR and low Ohm meter measuring range from 0.001 to 100.0R, support in circuit testing. Using true 100 KHz sine wave to measure the ESR value, which is equal to the testing method of capacitor manufacturer.
It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C).
The impedance become small, and we can then measure the true series resistor value.
Using this theory, we can measure the capacitor is bad/ damaged or good in condition.
Our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result we can use it as in circuit test.
During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not.
Dual terminal, for fast and easy inspect general capacitor or resistor, a printed ESR table for fast check.

O produto chegou mas no momento de testar percebi que o item veio com defeito pois com a pilhas inseridas o aparelho não funcionava, identifiquei que os fios de conexão da bateria estavam invertidos, fio vermelho no negativo e o fio preto no positivo do conector interno da bateria/pilha. Na conexão do micro-usb estava funcionando tudo ok. Apesar disso reparei os fios de forma correta e o aparelho agora está funcionado ok.
Thank you got everything right parabens
Done just a quick testing and I’m satisfied with devic. Realy neet device. Powered by 2 x AA batteries. It comes with two set test calipers. Device is quick.
Exactly as described. Quick to deliver and came safely. The meter was packed well, with the correct probes. The screen is pretty good for what it is and is clear enough to read for me. Thanks! Now to repair my subwoofer!
Thank you very much
Received the purchase everything right. Already in use.
El producto llego. Se tardo demasiado en llegar en mi domicilio. Se ve todo bien. Ahora falta probarlo vendedor recomendado.
Plecam quickly smoothly running like please
Perfeito. Exatamente como informado no anúncio. Superou minhas expectativas. Alta precisão.
Super fast shipping, received in 7 days. Product as described!
