The manual for the LC102 "AUTO-Z" capacitor inductor analyzer provides guidance on preliminary setup, testing various components, and troubleshooting issues such as the STOP TESTING alarm. It emphasizes the importance of zeroing the unit before testing, details the steps for testing non-electrolytic and electrolytic capacitors, and explains how to handle alarms and errors during operation.
Manual Overview
The Sencore LC102 AUTO-Z Capacitor-Inductor Analyzer manual provides detailed guidance on using the device for testing various components. The initial setup requires connecting the test leads and zeroing the circuits by shorting and then opening the leads to compensate for any changes. The STOP TESTING alarm indicates issues such as a blown fuse or excessive voltage, and testing must cease until resolved. For non-electrolytic capacitors, the process involves identifying the type, entering the ideal values, and testing for value and leakage. The analyzer’s microprocessor uses this data to determine if the component is within specifications, displaying a GOOD or BAD result. Electrolytic capacitors require additional tests due to their varied failure modes, including dielectric absorption and ESR, though the latter is not applicable to non-electrolytic types. Calibration and adjustments are crucial for accurate diagnostics, ensuring the device compensates for any variations in test conditions.
Quick Issues Covered
- Diagnose power-up failures by checking power adapter or battery.
- Use STOP TESTING alarm to identify test lead or protection issues.
- Trace circuits using schematics for lead zero calibration.
Overview
The LC102 “AUTO-Z” is a capacitor inductor analyzer designed for testing various electronic components. The manual provides a self-study course on its preliminary setup and testing procedures. Users are guided through the process of zeroing the circuits, testing different types of capacitors and inductors, and understanding the analyzer’s feedback, such as the STOP TESTING alarm. The manual emphasizes the importance of rezeroing the device before testing components, especially those with small values, and provides detailed instructions for testing non-electrolytic and electrolytic capacitors, including value, leakage, and dielectric absorption tests.

Installation / Setup
Before testing any components with the LC102 “AUTO-Z” capacitor inductor analyzer, it is important to zero the LC102 circuits. This involves connecting the test leads, applying power, and using the LEAD ZERO switch to compensate for short and open circuits. The microprocessor will adjust for the test leads, and it is recommended to rezero the unit each time it is turned on or before testing small value components. If the STOP TESTING alarm activates, testing should be halted immediately, and the cause of the alarm should be addressed before resuming.
Operation
The LC102 “AUTO-Z” capacitor inductor analyzer requires a preliminary setup before testing components. Users should zero the LC102 circuits by connecting the test leads, applying power, and using the LEAD ZERO switch to short-circuit and open-circuit positions. This compensates for the test leads. The STOP TESTING alarm activates if there’s a test lead input fuse opening, protection circuit opening, or if test leads are connected to a point with 10 volts or greater. Users should stop testing, discharge any capacitors, replace blown fuses, and remove voltage from the test point before resuming.
For non-electrolytic capacitors, identify the type and enter ideal values into the LC102. Test for value and leakage, as these tests find most bad capacitors. The ESR test is not applicable for non-electrolytic capacitors. For electrolytic capacitors, perform all four tests due to their multiple failure modes, entering type, ideal value, tolerances, and voltage rating.

Safety & Warnings
The manual includes the following safety warnings and precautions:
1. Before testing any components, zero the LC102 circuits. This involves connecting the test leads, applying power, and using the LEAD ZERO switch to set the circuits to zero.
2. If the LC102’s STOP TESTING alarm is activated, stop all testing immediately. This alarm can be triggered by the test lead input fuse opening, protection circuit opening, or connecting the test leads to a point with 10 volts or greater.
3. If the STOP TESTING alarm activates, follow these steps:
– Stop all testing with the LC102.
– Carefully discharge the capacitor being tested by connecting a 10k ohm 1 watt resistor across the terminals.
– Replace the test lead fuse if blown, or remove the voltage from the point the test leads are connected to.
– Resume testing.
4. A warning is given that a flashing light indicates a leakage test is being performed, and the STOP TESTING protection circuit is active.
