Sencore introduces its In-Circuit Capacitor/Inductor Analyzer:

Pinpoints bad capacitors and inductors "in-circuit," and automatically tells you when further out-of-circuit tests are required.
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

Tests SMT components "in-circuit" and accurately with exclusive, time-saving test accessories.
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

Makes all tests, compares the results to EIA standards, and tells you "GOOD" or "BAD" - automatically.
Tests SCRs and triacs with optional SCR250 accessory.

LC103 Condensed Specifications:

IN-CIRCUIT TESTS (Capacitors and Inductors):
- Dynamic in-circuit tests to determine whether the component is good or bad.
Component Types: Electrolytic, double layer lytic, tantalum, ceramic, and other capacitors.
Yokes, flybacks, switching transformers, and coils.
Inductor Range: 3.18 uH to 3.18 H
Capacitor Range: 0.002 uF to 20,000 uF
Accuracy: Same as Out-of-Circuit tests for known good inductors and capacitors with no parallel
current paths.
Suggest Removal Indication: Initiated when AC test differs from DC test by more than 20%,
or if low level DCR test indicates a leakage path greater than 20% of charge current for capacitors.

CAPACITORS (Out-of-Circuit):
Value: Dynamic test of capacity value is determined by applying a constant current to the capacitor
and measuring the dV/dt.
Range: 1 pF to 20 F
Accuracy: ±1%, ±1 pF, ±1 digit for values to 1990 uF, ±5%;
±0.1% of range full scale for values 2000 uF to 20 F

EQUIVALENT SERIES RESISTANCE (ESR):
Accuracy: ±5%, ±1 digit
Capacitor Range: 0.01 uF to 20 F

DIELECTRIC ABSORPTION:
Accuracy: ±5% of reading, ±1 count
Range: 1 to 100%
Capacitor Range: 0.01 uF to 20 F

LEAKAGE:
Accuracy: ±5%, ±1 digit
Applied Voltage: Keyboard entry 1.0 to 1000 volts in 0.1 volt steps short circuit current limited to 900 mA

INDUCTORS (Out-of-Circuit):
Value: A dynamic test of value determined by measuring the EMF produced when a changing current
is applied to the coil under test
Range: 0.1 uH to 20 H
Accuracy: ±2%, ±1 digit, ±0.1 uH

RINGING TEST:
- A dynamic test of inductor quality determined by applying an exciting pulse to the inductor and counting the number of cycles the inductor rings before reaching a preset damping point.
Inductor Range: 10 uH and larger, non-iron core
Accuracy: ±1 count on readings between 8 and 13 Rings
Resolution: ±1 count
Exciting Pulse: 5 volts peak

GENERAL:
Temperature Operating Range: 32¡ to 104¡ F (0¡ to 40¡ C)
Temperature Range for Specified Accuracy (after 10 minute warm-up): 50¡ to 86¡ F (10¡ to 30¡ C)
Power: 105-130V AC, 60Hz, 30 watts with supplied PA251 power adapter.
Battery operation with optional BY289 rechargeable battery.
Auto-Off: Removes power during battery operation if unit sits idle longer than 5 minutes.
Battery Life: 2 hours typical operation
HxWxD Size: 6" x 9" x 11.5" (15.2 cm x 22.9 cm x 29.l cm)
Weight: 6.0 lbs. (2.7 kg) without battery, 7.6 lbs. (3.4 kg) with battery
GOOD/BAD Indication: Functions on all tests.
Requires user input of component type and value, or input of desired limits.
