MESR100 AutoRanging In Circuit ESR Capacitor Meter Tester Up to 0.001 to 100R with 2 pairs Probes


Feature:
 
  • 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.
    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

    *Accuracy maybe affected by the test lead length and contact point resistance.

    Standard test leads is 15cm, for longer test leads need special shielding to affect the EMI inference (Can contact sales person for more detail)
