When voltage is first applied, the capacitor has no charge stored and so has 0 V across it. The voltmeter should then read VS. As the capacitor charges up, its voltage will increase. KVL then says that the voltmeter reading should decrease. For an ideal capacitor, the voltmeter should eventually read 0 V as the capacitor is fully charged and has a voltage equal to VS. For practical capacitors, the voltmeter should read a very small voltage. Large electrolytic capacitors may have leakage current that makes them appear bad, especially with a very high impedance voltmeter. In this case, use the test as a relative test, comparing the reading with a similar capacitor that you know is good.
From your kit, retrieve the capacitors whose value is given in Table 6-1 below. On the DMM, select the  Ω2W  button to use the DMM as an ohmmeter. Using the softkeys, change the Range from Auto to 600 kΩ. Check each capacitor using the ohmmeter test described above. Record the results of the test in Table 6-1.
On the DMM, select the  DCV  button to use the DMM as a voltmeter. Test each capacitor using the voltmeter test as illustrated in Figure 6-1. Use VS = 20 V. Large electrolytic capacitors may appear to fail this test. Check the voltage rating on the capacitor to be sure it is not exceeded. The working voltage is the maximum voltage that can safely be applied to the capacitor. Record your results in Table 6-1.
