Normally, a big capacitor is larger than 3 ohm.<br>Using this theory, we can measure the capacitor is bad/ damaged or good in condition.<br>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.<br>During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not.<br>*Dual terminal, for fast and easy inspect general capacitor or resistor, a printed ESR table for fast check<br>Compare MESR100 old V1 and new V2 Improvement:<br>1)<br>Change square wave to sine wave 100 KHz, reduce square wave’s high frequency component, and affect the reading passing the test leads and capacitor.<br>2)<br>Higher Resolution up to 0.001 ohm.<br>3)<br>128X64 dot matrix LCD, with more larger value display and information<br>4)<br>Embedded 25V capacitor table at LCD, auto display the capacitor is good or bad reference to common 25V electrolytic capacitor.<br>5)<br>New plastic case, curve design for hand carrying.
