The manual for the Sencore LC103 In-Circuit Capacitor Test covers how to effectively test capacitors without removing them from the circuit, using the Adjustable In-Circuit Test Probe to overcome mechanical challenges and ensure accurate measurements. It also provides guidance on interpreting test results, troubleshooting potential issues, and understanding the impact of parallel components on test accuracy.
Manual Overview
The Sencore LC103 “ReZolver” offers a method for testing capacitors in-circuit, addressing challenges such as maintaining stable electrical connections and interpreting results. The device uses an Adjustable In-Circuit Test Probe (AP291) to facilitate connections to various capacitor types, including surface mount and large electrolytics, without desoldering. This probe features an adjustable spacing wheel and angled tips for ease of use, and a push button switch to prevent probe slippage during testing. The LC103 performs tests to determine capacitor value and equivalent series resistance (ESR), providing a Good/Bad analysis based on these measurements. It accounts for parallel components that may affect test accuracy by using sophisticated tests, including current and frequency analysis. The LC103 beeps to signal test completion, freezing the display for result review. It offers two testing alternatives: a basic Good/Bad test and a complete EIA Good/Bad test, each with slightly different display readouts. These features aim to reduce servicing time and expense by providing reliable in-circuit capacitor assessments.
Quick Issues Covered
- Diagnoses capacitors with in-circuit Good/Bad test for reliability.
- Calibrates using adjustable probe for various capacitor sizes.
- Assists in circuit tracing with schematic analysis for parallel components.

Basic Usage and Operation Tips
To use the LC103 in-circuit capacitor tester effectively, connect the test leads to the capacitor terminals while the capacitor remains soldered in the circuit. Ensure the device is powered on and calibrated according to the manual instructions. Observe the digital display for capacitance readings and compare them against the expected values for the specific capacitor. For best results, test capacitors when the circuit is powered off to avoid interference and potential damage. Regular calibration of the tester is recommended to maintain measurement accuracy.
Troubleshooting and Maintenance Notes
If the tester displays inconsistent or no readings, verify all connections and ensure the test leads are intact. Clean the test probes regularly to prevent oxidation and poor contact. Should the device fail to power on, check the battery or power source and replace if necessary. Avoid exposing the tester to moisture or extreme temperatures to prolong its lifespan. For persistent issues, consult the detailed troubleshooting section in the manual or contact Sencore technical support.
Safety Reminder
Always ensure the electronic circuit under test is powered down before connecting the tester to avoid electric shock or damage to the device. Use caution when handling electronic components and follow standard electrostatic discharge (ESD) precautions. Keep the tester away from high voltage sources and liquids to ensure safe operation.
