1.1.2 Operating Modes
The four operating modes of SLM-series DC electronic load include: Constant Current (CC) mode,
Constant Resistance (CR) mode, Constant Voltage (CV) mode, and Constant Power (CP) mode. The
wide-range dynamic load with independent rise/fall current slew rate and analog programming input
with arbitrary waveform input, is available in Constant Current and Constant Power modes. This
dynamic feature enables SLM-series DC electronic loads to simulate real world loads.
CC Mode:
In Constant Current mode, the load will sink a current in accordance with the programmed
current setting regardless of the input voltage (see Figure 1-6).

CR Mode:
In Constant Resistance mode, the load will sink a current linearly proportional to the load input
voltage in accordance with the programmed resistance setting (see Figure 1-7).
