Grady Memorial Hospital The Department of Psychiatry at Grady Memorial Hospital provides mental health care to people living in central Fulton County as well as the surrounding region. The department is an integral part of the State of Georgia mental health system and is located in a large urban community general hospital.
If the capacitor is an axial version having leads at both ends of the package, the polarity marking stripe may be accompanied by an arrow that points to the negative lead. For leaded tantalum capacitors the polarity markings indicate the positive lead. A + sign is placed close to the positive lead. When new, a further polarity making may be used because it may be seen that the positive lead is longer than the negative one.
YOU CANNOT DISCHARGE A START CAPACITOR LIKE A RUN CAPACITOR WITH A SCREWDRIVER! Many / most of the time, the start capacitor will have a bleed resistor attached. Switch the ohmmeter to the Volts AC position. To discharge the start capacitor, use your multimeter in the volts AC mode. Touch the leads, one each, to the capacitor's terminal connectors. Hold the leads in place to discharge the capacitor of any power. The meter may register some form of voltage value, but should soon dissipate down to zero volts. When the start capacitor has been fully discharged, switch the meter to the Ohms position on the meter's switch. Remove the red lead from the Volts connector and place it into the ohms connector. Touch the two leads to the two terminals of the capacitor. The resistance reading should begin at zero ohms and then slowly climb in the resistance-reading display. This indicates that the capacitor is storing a small electric charge from the meter. The capacitor is good. The capacitor is bad and should be replaced if: 1.If the meter immediately shows a very high resistance reading, in which case the capacitor has an open in the circuit. 2.If the meter remains at zero ohms and does not climb in the reading.
