Operation
The operation of the LC75 Capacitor-Inductor Analyzer involves several steps for testing capacitors and inductors. For capacitor tests, the process includes opening the test leads, setting the leakage range, adjusting for a 00.0 readout, connecting the capacitor to the test leads, selecting the desired voltage for the leakage test, and pushing the button to read the value, leakage in microamperes, and ESR in ohms on the display. For inductor tests, the steps include shorting the test leads, adjusting for a 00.0 readout, connecting the coil, yoke, or flyback, and pushing the button to read the value in microhenries and the ringing test on the display. A reading of 10 or more indicates a good component.

Safety & Warnings
Do not attempt to check capacitors in-circuit. This instrument is to be operated by a technically trained person only, who understands the shock hazard of up to 600 Volts applied to test leads during capacitor leakage tests. Do not use this instrument in circuits with power applied; it is designed to be used with the power removed from the unit being tested. Remove the AC line cord and discharge filter capacitors before making any test lead connections. Never exceed the limits of this instrument as given in the specification section and the additional warnings in this manual. A severe shock hazard can result if the chassis of the equipment being tested is tied to the “hot” side of the AC line. Always remove the AC line cord when testing components with this type of equipment. If the unit is to be put into operation, use an isolation transformer. Ensure that the top of the bench and the floor underneath it are dry and made of non-conducting material. Ensure your equipment is in good order; broken or frayed test leads can cause improper test results. Remove the test leads immediately after the tests have been completed to reduce the possibility of shock. Do not work alone when working on hazardous circuits; always have another person close by in case of an accident. Improper fuses void the warranty; always replace fuses with the proper type and current rating. Do not defeat the third wire ground on the AC line cord; it ensures correct capacity readings on low-value capacitors and voiding it will void the warranty.
