## Overview

The MESR-100 by Geevorks is a professional-grade ESR and low Ohm meter designed for in-circuit capacitor testing. Featuring an ultra-precise 0.001 to 100Ω auto-ranging measurement, it uses a 100kHz sine wave to accurately assess capacitor health with minimal voltage impact. Powered by 2 AA batteries, it offers over 80 hours of operation, dual terminals for quick testing, and a handy ESR reference table, making it an essential tool for electronics repair professionals and enthusiasts alike.

## Description

Full description not available

## Features

- This MESR-100 auto-ranging capacitor ESR and low Ohm meter measuring range from 0.001 to 100.0R, support in circuit testing.
- Capacitance meter 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.
- 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.
- 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.[Note: without SMD test clips]
