4-3 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 3310F 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.

4.3.1 Static mode: (Fig 4-3)

Major application areas include:

• Voltage source testing

• Power supply load regulation testing

• Battery discharge testing
