GeevorksMESR-100 Capacitor Tester V2, Geevorks Professional Capacitor Tester, Ohm Meter 0.001-100.0R with SMD Test Clip, Auto-Ranging Capacitor for Measuring Capacitance Resistance Circuit
Main highlights- This MESR-100 V2 auto-ranging capacitor ESR and low Ohm meter measuring range is 0.001-100.0R, support in circuit testing.
- 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.【Note:The Capacitance Meter is used for testing the internal resistance of the capacitor, not for testing capacitance value.】
- Dual terminal, for fast and easy inspect general capacitor or resistor, a printed ESR table for fast check.Equipped with a SMD alligator clip for more accurately testing.
- Capacitor tester is the series resistance inside the capacitor, and 100kHz is used to remove the impedance 1/(2*pi*F*C). When the impedance becomes smaller, the real series resistance value can be measured to determine whether the capacitor is bad/damaged or in good condition.
