Prodigit 3310F Series - Fig 1-6 Constant Current Mode; Fig 1-7 Constant Resistance Mode

3310F Series Operation Manual 3
The 3310F series of electronic load modules feature 4 operating modes. These are
Constant Current ( CC ) mode, Constant Resistance ( CR ) mode, Constant Voltage ( CV )
mode, and Constant Power ( CP ) mode.
Along with static operation the loads can also be programmed to operate dynamically in
CC, CR or CP modes. An analogue programming input on the mainframe allows the 3310F
series load module to track an external signal. For example a dynamic waveform can be
set up on an external generator. The load will follow this signal assuming it is within it’s
range of dynamic response.
1.1.1. CC Mode
With the operating mode of Constant Current, the 3310F series electronic load will sink a
current in accordance with the programmed value regardless of the input voltage (see
Fig.1-6).

1.1.2. CR Mode:
At Constant Resistance mode, the 3310F series Electronic Load will sink a current linearly
proportional to the load input voltage in accordance with the programmed resistance
setting (see Fig 1-7).
