## Overview

The MESR-100 by Geevorks is a professional-grade ESR and low Ohm meter designed for in-circuit capacitor testing. Featuring an ultra-wide 0.001 to 100Ω auto-ranging scale with 1% accuracy, it uses a true 100kHz sine wave to deliver precise ESR measurements without removing components. Powered by 2 AA batteries, it offers over 80 hours of continuous use, making it an essential tool for electronics repair professionals and enthusiasts aiming to diagnose capacitor health quickly and reliably.

## Description

This MESR-100 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 w-ave to measure the ESR value, which is equal to the testing method of capacitor manufacturer.Features: It 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. Using this theory, we can measure the capacitor is bad/ damaged or good in condition. Our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a r-esult 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. Dual terminal, for fast and easy inspect internal resistance of the capacitor, a printed ESR table for fast check.Note: The Capacitance Meter is used for testing the internal resistance of the capacitor, not for testing capacitance value.Specifications: Color: Black Accuracy: Up to 1% Wide Measurement Range: >1uF High Resolution: 4 digit, or 0.001Ohm @ 1 Ω range Measuring voltage: 80 Hours Item Size: Approx 14.5 * 8 * 3cm / 5.7 * 3.1 * 1.2in Item Weight: Approx 139.6g / 4.9oz Package Size: Approx 17 * 9 * 5cm / 6.7 * 3.5 * 2.0in Package Weight: Approx 218g / 7.7ozPackage List: 1 * Capacitance Meter 2 * Test Clips 1 * User Manual
