Information

Capacitor and inductor usage in electronic equipment is increasing rapidly and the forecast is for this growth to continue. Much of the increased use of capacitors and inductors is due to the increasing use of the integrated circuit. ICs are taking the place of discrete components in many electronic circuits. Due to their construction however, capacitors and inductors are not contained within the IC package, but rather remain as discrete components. To meet the requirements of todays IC circuits, capacitors and inductors have tighter tolerance and more critical parameters than ever before. As the use of ICs increases, so will the usage of capacitor and inductors. The need to measure critical capacitor parameters and inductor value and quality is greater than ever before. Without a good reliable measurement of these parameters, circuit troubleshooting becomes difficult. The Sencore LCIG1 Z METER meets this challenge. It allows capacitors to be checked for value, ESE and leakage at their rated working voltage. The LC101 also provides a patented dielectric absorption test. Inductors are readily tested for value with a patented inductance test and for quality with a patented ringing test. The LC101 is a complete capacitor and inductor Analyzer. Features The Sencore LC101 Z METER is a complete, capacitor and inductor Analyzer (4 patents) designed to locate defective components. Simply hook the capacitor or inductor to the test leads, push a button and the LC101 automatically displays the value on the digital readout. In addition to checking value, the LC101 also checks capacitors for leakage at their rated working voltage from 1.5 to 1000 volts. A flashing LED serves as a safety reminder when the voltage applied to the capacitor is 35 volts or higher. A patented dielectric absorption test and patented ESE test round out the capacitor checks, making the LC101 a unique* thorough capacitor Analyzer. The Sencore patented inductance value test provides a fast, reliable check of true inductance. The Sencore patented ringing test checks coils, deflection yokes, and other non-iron core transformers with an accurate good/bad check. Six impedance matching settings match coils from 10µH to 10H to the test circuit. Good coils show 10 or more ringing cycles on the digital display while bad coils show less than 10. A LEAD ZERO control allows you to balance out test lead capacity and inductance for accurate readings of very small capacitors and coils. The Z METER is protected against accidentally being applied to the test leads by a front panel, replaceable fuse and a special relay inside the instrument.
