Cheap auto range, Buy Quality ohm test directly from China in circuit esr meter Suppliers: EWS MESR-100 Auto Ranging in Circuit ESR Capacitor / Low Ohm Meter Up to 0.001 to 100R, Support in Circuit Testing Black+Oran
Using true 100 KHz sine wave to measure the ESR value, which is equal to the testing method of capacitor manufacturer. Dual terminal, for fast and easy inspect general capacitor or resistor, a printed ESR table for fast check. Measuring range from 0.001 to 100.0R, support IN CIRCUIT Testing. Auto-ranging capacitor ESR and Low Ohm Meter. Wide Measurement Range. Using 100kHz to remove the impedance 1/(2*pi*F*C), the impedance will become small, and then we can measure the true series resistor value. A bad E-capacitor have larger ESR and create large ripple rather than filtering noise. Normally, a big capacitor is larger than 3 ohm. Therefore, we can measure the capacitor is bad, damaged or in good condition by using this theory. Because 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. Because this low testing voltage, it cannot turn on the semiconductor inside a circuit under testing. During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not. Using true 100 KHz sine wave to measure the ESR value,
