MESR-100 AutoRanging In Circuit ESR Capacitor/Low Ohm Meter Up to 0.01 to 100R (Orange)
- JINGYAN 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.
- In the market, there is some technique using short pulse method to testing, but the value will be varying vs the capacitance and sometimes reading is different from the manufacturer's value.
- What is ESR of capacitor?
- There 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.
- A bad E-capacitor will have larger ESR and create large ripple rather than filtering noise. Normally, a big capacitor is larger than 3 ohm.
- Using this theory, we can measure the capacitor is bad/ damaged or good in condition.
- 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.
