JINGYAN MESR-100 V2 Auto-Ranging ESR and Low Ohm Meter

Overview

The JINGYAN MESR-100 V2 is a sophisticated auto-ranging meter designed for accurately measuring Equivalent Series Resistance (ESR) in capacitors and low resistance values. This device operates within a range of 0.001 to 100.0 ohms, making it ideal for in-circuit testing without the need to remove components from their circuits.

Key Features

• Measurement Range: Capable of measuring from 0.001 to 100.0 ohms.
• In-Circuit Testing: Allows testing of capacitors while they remain connected in the circuit.
• True Sine Wave Measurement: Utilizes a true 100 KHz sine wave for accurate ESR readings, aligning with manufacturer testing methods.
• Improved Accuracy: Offers an accuracy rate of up to ±1%, ensuring reliable results across various ranges.

Enhanced Specifications

• High Resolution Display: Features a clear 128×64 dot matrix LCD that provides detailed information and larger value displays.
• Capacitor Reference Table: An embedded table on the LCD helps quickly determine if a capacitor is functioning properly based on common standards (25V electrolytic).

Design Improvements Over Previous Model

1. Transitioned from square wave to sine wave measurement at 100 KHz, reducing interference and improving accuracy.
2. Increased resolution capability down to 0.001 ohm for precise measurements.
3. New ergonomic plastic casing with an integrated stand that allows for easy handling at a comfortable viewing angle (60 degrees).
4. Powered by two AA batteries, offering longer life compared to traditional 9V batteries; also supports external power via micro USB.

Operational Guidelines

1. Powering On/Off: Hold the orange ON/OFF button for two seconds; press again briefly to turn off.
2. Mode Selection:

– Auto Mode automatically selects optimal measurement range upon pressing RANGE button.
– Manual Mode allows users to select specific ranges (1R, 10R, or 100R).

1. Zero Calibration: Short circuit test leads before pressing ZERO button ensures accurate readings by eliminating lead resistance.

Practical Applications

This meter is particularly useful during repairs involving televisions, audio equipment, or any electronic devices where capacitor integrity needs verification without disassembly.
