      Description:

      Features:

      • 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

      Specification:

      • Range Accuracy (After Zero, tested with 1,10,100R resistor) Refresh Time (Manual Mode)*Auto mode take 0 to 2s more time depend on value
        0.000 to 1.000R 1%+2Digit ~0.4s
        1.000 to 10.00R 1%+1Digit ~0.4s
        10.00 to 100.0R 2%+1Digit ~0.4s
        *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)

        1) Accuracy: Up to 1% (detail on above table)
        Wide Measurement Range: >1uF (for 0.1uF the error will be larger on equation 1/(2*pi*F*C) @ 100Khz )
        2) High Resolution: 4 digit, or 0.001Ohm @ 1 Ohm range
        3) Measuring voltage: <~40mV RMS (TESTING VOLTAGE)
        4) Clamping voltage: ~0.15V (open voltage)
        5) Battery: 2X AA 1.5V battery (not include in the packing)
        6) External Power: 5V micro USB
        7) Operating current 0.02A
        8) Battery Life time: >80 Hours

      Package Content:

      • 1 x MESR-100
      • 1 Pair test probe
      • 1 Pair Test Clip Probe
