6.4.1 Constant Current Mode (CC)
In this mode, the electronic load will sink a constant current in accordance with
the programmed value regardless of the input voltage. See figure as follow.
6.4.2 Constant Resistance Mode (CR)
In this mode, the electronic load was equivalent to a constant resistance, as
shown below, the electronic load will linearly change the current according to the
input voltage. See figure as follow.
6.4.3 Constant Voltage Mode (CV)
In this mode, the electronic load will attempt to sink enough current to control
the source voltage to the programmed value. See figure as follow.
6.4.4 Constant Power Mode (CP)
In CP mode, the load will consume a constant power. See Figure as follow. If
the input voltage rises, the input current will decline. The P (=V * I) will remain
on the set power.
