Additional Information

The identification tables below help reference the waveform for each test. In place of the time to charge the capacitor, in Section 4, is a number that corresponds to the relevant figure number. All of the figures in this section are labeled as 5-#. The second number is the number from the key table. For example, to look at waveform 6 from the Table 5-1, please refer to Figure 5-6.
