This eBook shows you how to TEST COMPONENTS. To do this you need "TEST GEAR." The best item of Test Gear is a MULTIMETER. It can test almost 90% of all components. And that's what we will do in this eBook:CONTENTSA nalogue MultimeterAudio StagesBatteries- testingBurnt ResistorBuying A MultimeterCapacitorsCapacitors -decoupling capsCapacitors in ParallelCapacitor Substitution BoxCells- batteriesCircuit SymbolsCo-Ax CablesColour Code (Resistor)CoilsContinuity Creating any value of RMultimetersNon-polar Capacitor (electrolytic)Open Circuit"Open" Resistor- damagedOpto-couplersParallel- resistorsParallel and Series Capacitors Piezo Diaphragms Piezo BuzzersPotentiometersPots- testing Power DiodesPower Supply -see Basic Electronics 1A Reed SwitchRelaysRemote ControlsCurrent - measuringCurrent Sensing ResistorsCurrent TransformerDamper DiodesDarlington TransistorsDigital ChipsDigital MultimeterDigital TransistorsDiodes replacing a diodeDischarge a CapacitorEarth Leakage DetectorsElectrolyticsFETsFingers- to feel temperatureFocus pots Fuses and 100mA fusesGermanium DiodesHeatsinksImpeda

By simply touching different items you can quite often feel a hot item and home-in on the fault - at a saving of hours of work. Servicing is not "A bull at a gate" approach.
