DESCRIPTION
INTRODUCTION
Capacitors and inductors are widely used in electronic
systems. Capacitor and inductor usage continues to
increase since neither of these components can be
physically incorporated into ICs on a broad basis.
Though capacitors and inductors have changed in
physical size, they still perform the same basic functions.
In today's high tech electronic circuits, capacitors and
inductors are critical to normal circuit operation.
In today's high performance circuits, value, leakage,
dielectric absorption, and ESR are important indicators
of a capacitor's ability to perform properly in-circuit.
Inductors too, must be of proper value and quality.
Unless all of these parameters are thoroughly analyzed,
problem capacitors and inductors may be missed and
troubleshooting becomes a guessing game.
The Sencore LC103 ReZolver takes the guesswork out
of capacitor and inductor testing. It provides in-circuit
capacitor value and ESR tests along with automatic out-
of-circuit tests for capacitor value, leakage, ESR, and
dielectric absorption. Inductors are automatically
analyzed in-circuit for value or out-of-circuit for value
and quality with patented tests.
The LC103 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.
FEATURES
The Sencore LC103 ReZolver is a dynamic, portable,
automatic, in- or out-of-circuit capacitor and inductor
analyzer. It is designed to quickly identify defective
capacitors and inductors by providing fast in-circuit tests
and complete analyzing out-of-circuit. The test results
are displayed on an easy-to-read fluorescent display 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).
In addition to testing capacitors for value up to 20
Farads, the LC103 checks capacitors for leakage at their
rated working voltage, up to 1000 Volts. ESR is
checked with a patented test, and an automatic, patented
test checks for excessive dielectric absorption. A
patented inductance value test provides a fast, accurate
test of true inductance. A patented ringing test checks
coils, deflection yokes, 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 test
results. The LC103 is protected from external voltages
applied to the test leads by a fuse located on the front
panel. Stop-testing circuitry locks out all test buttons
when voltage is sensed on the test leads.
Battery operation makes the LC103 completely portable
for on-location troubleshooting in all types of servicing
including industrial equipment, avionics, and cable fault
locating. An optional SCR260 SCR & TRIAC TEST
ACCESSORY extends the LC103 test capabilities to
provide a fast, accurate test of these components. The
LC103 may be used with an RS-232 computer interface
for fully automatic, computer controlled testing in a
laboratory or incoming inspection area.
