ReZolver In-Circuit Capacitor Inductor Analyzer

Marketing Information

The LC103 ReZolver™ Capacitor and Inductor Analyzer takes the guesswork out of capacitor and inductor testing. The ReZolver™ is a complete, automatic, microprocessor-controlled analyzer ideally suited for service, maintenance, or large volume testing in a lab or incoming inspection.

The ReZolver™ gives you the ability to accurately pinpoint defective capacitors without removing them from the circuit. Using exclusive tests, the ReZolver™ measures the capacitor's value and ESR, checks for parallel components that may otherwise disrupt the measurements, and gives a GOOD/BAD/SUGGEST REMOVAL evaluation.

Dynamically analyze capacitors out-of-circuit for all four failure modes: value (to 20 Farads), dielectric absorption (D/A), leakage (up to 1000 applied volts) and equivalent series resistance (ESR).

Features

• Pinpoints bad capacitors and inductors "in-circuit," and automatically tells you when further out-of-circuit tests are required
• Tests SMT components "in-circuit" and accurately with exclusive, time-saving test accessories
• Makes all tests, compares the results to EIA standards, and tells you "GOOD" or "BAD" - automatically
• Analyzes capacitors for all four failures out-of-circuit: Value from 1 pF to 20 F, Equivalent series resistance, Leakage with up to 1,000 volts applied, Dielectric absorption
• Analyzes inductors with exclusive patented tests for: Values from 0.1 uH to 20 H, Opens or shorts, Even one shorted turn with patented "Ringer" test
• Tests SCRs and triacs with optional SCR250 accessory
