## Description

Product Description

Review: Useful product - Good product
Review: Smart components Identify and Original parts value for SMPS and Charges repairs - Excellent product for SMPS, Chargers, Adapter repair on Components level to identify the Tranistor NPN PNP, True Capistance with ESR , Resistance, Inductor, Trac etc My Hi-end 4K HDR Player SMPS with multi voltage was giving Trouble while playing Disc and Layer changing BDXL. I tested Reference Resistance and Tank capistor and ref. Capistor was Having half value. I tested with this device and got New Parts first tested with this Device. I was amazed that less value on parts then description. So I got ref value parts and now NO freezing of Disc while laser change to 3rd Layer in BDXL movie Discs 4k HDR+

## Features

- Transistor Capacitor Tester: FNIRSI LCR-P1 transistor tester can be used for the measurement and analysis of patch component, NPN, PNP, triode, MOS, field effect transistor (FET), diode, Zener diode, capacitor, resistor, inductor, battery, etc
