The Sencore LC102 AUTO-Z takes the guesswork out of capacitor and inductor testing. It provides automatic tests of capacitor value, leakage, EST, and a patented dielectric absorption test. Inductors are automatically analyzed for value and quality with patented tests. The LC102 is a complete, automatic, microprocessor-controlled capacitor and inductor analyzer. Its features make it ideally suited for both single, component analyzing in service or maintenance work or for large volume batch testing in a lab or incoming inspection.

The Sencore LC102 AUTO-Z is a dynamic, portable, automatic capacitor and inductor tester. It is designed to quickly identify defective components by simply connecting the capacitor or inductor to the test leads and pushing a test button. The test result is readily displayed on an LCD readout in common terms. All capacitor and inductor test results may also be displayed as GOOD/BAD compared to standards adopted by the Electronic Industries Association (EIA). User defined limits may also be programmed into the LC102 for the GOOD/BAD comparison.

In addition to testing capacitors for value up to 20 Farads, the LC102 checks capacitors leakage at their rated working voltage, up to 1000 colts. ESR is checked with a patented test, and an automatic, patented test checks capacitor dielectric absorption. A patented inductance value test provides a fast, accurate test of true inductance. A patented ringing test checks coils, deflection yoke, switching power supply transformers, and other non-iron core inductors with a fast, reliable GOOD/BAD quality test.

Automatic lead zeroing balances out test lead capacitance, resistance, and inductance for accurate readings on small capacitors and inductors. The LC102 is protected from external voltages applied to the test leads by a fuse in the TEST LEAD JACK and a special stop testing circuitry which locks out all test buttons when voltage is sensed on the test leads.

Battery operation makes the LC102 completely portable for on-location troubleshooting in all types of servicing from industrial equipment to avionics to cable fault locating. 

An optional SCR250 SCR and Triac Test Accessory extends the LC102 test capabilities to provide a fast, accurate test of these components (sold separately).

The LC102 may be interfaced into any computer interface system for fully automatic, computer controlled testing in a laboratory or incoming inspection area.
