High Power DC Electronic Load 63200 Series Operation & Programming Manual
You can program two different static settings, A and B under all static CC, CR, CV, and CP
modes. Both A and B states use the same range. You can select A or B through the A/B
key. Slew rate determines the rate that Load level changes from one state to another.
Figure 3-4 shows the load current level after pressing A/B key.

Dynamic load operation enables you to program two load levels (CCDL1, CCDL2), load
duration (CCDLT1, CCDLT2), and slew rate (CCDL , CCDL ). The loading level is
switched between those two load levels according to your specific setting during operation.
The dynamic load is commonly used to test the UUT’s performance under transient loading
condition. Figure 3-5 shows current waveform of dynamic function.
