Constant Current Mode Application - Prodigit 34000A Series Operation Manual

5-3. Constant Current mode application

The Constant Current (CC) mode is ideal for testing the Load Regulation, Cross Regulation,
Output Voltage and Dynamic Regulation of the power supply under test. The CC mode can
also be used to test the Discharge Characteristics and the Life Cycle of cells and battery
packs. In CC operation the 34000A series can operate as a static load with switchable high
and low current levels. It is also possible to operate the load dynamically enabling the user
to adjust sink current with time.
