Accurately diagnose capacitor health and ensure reliable circuit repairs with this advanced ESR Meter, designed to measure the equivalent series resistance (ESR) of capacitors using a 100kHz test frequency. By effectively removing the capacitive reactance impedance, this meter allows you to measure the true series resistor value inside capacitors, enabling precise detection of damaged or faulty components without removing them from the circuit. Key Features: · Precise ESR Measurement at 100kHz: Utilizes a high-frequency signal to minimize capacitive impedance, providing accurate readings of the series resistor inside capacitors for reliable condition assessment. · In-Circuit Testing Capability: Applies less than 15mV DC or peak-to-peak voltage on capacitors, allowing safe and convenient testing directly on TV, LCD, audio boards, and other electronic devices without disassembly. · Dual Terminal Design: Equipped with dual test clips for fast and easy inspection of general capacitors and resistors, improving efficiency during troubleshooting and repair tasks. · Clear ESR Reference Table: Includes a printed ESR chart for quick comparison and fast evaluation of capacitor condition, streamlining the diagnostic process. · Wide Measurement Range and High Resolution: Measures ESR values from 0.000 to 100.0 ohms with accuracy up to 1%, featuring a high-resolution 4-digit display capable of 0.001 ohm precision at 1 ohm range. · Long Battery Life and Convenient Power Options: Powered by 2 AA batteries (not included) with over 80 hours of continuous use, and supports external 5V micro USB power for flexible operation. · Compact and Lightweight: Measuring 14.4 x 8.1 x 3.1 cm and weighing approximately 219g, this portable meter is easy to handle and store, ideal for technicians and hobbyists alike.
