Manual Overview

The Sencore LC103 “ReZolver” is an advanced in-circuit analyzer designed to efficiently test capacitors and inductors without the need for removal from the circuit board. It features a patented technology that allows technicians to perform accurate in-circuit tests, saving time and reducing the risk of damaging components. The LC103 includes an adjustable in-circuit test probe that simplifies the testing process by allowing quick connection to component terminals. It provides comprehensive diagnostics by measuring capacitance, equivalent series resistance (ESR), and dielectric absorption (DA), and can handle a wide range of capacitor values from 1pF to 20F. The analyzer also features a parallel component check to ensure measurement accuracy and offers a GOOD/BAD/SUGGEST REMOVAL message based on EIA standards. For inductors, the LC103 performs a true inductance measurement, avoiding errors from frequency or calculation. Additionally, the patented Ringer test helps identify issues in transformers and flybacks by detecting single shorted turns. This tool is essential for technicians aiming to improve troubleshooting efficiency and accuracy.
