Constant resistance operation mode (CR)
Under CR mode, the electronic load is equivalent to a constant resistance (as
shown below) and will give linear change of current with input voltage change.
As shown in Fig. 3-3.
Fig. 3-3 Voltage-Current Relation Schema under CR Mode
Under CR mode, the electronic load provides three ways to modify constant
resistance.
⚫
Rotate adjusting knob to set constant resistance value.
⚫
Use numeric keys to input resistance value and press [Enter] key to confirm
set constant resistance value.
⚫
Use
moving cursor and press
to adjust values at
corresponding positions.

Constant power operation mode (CW)
Under CW mode, the electronic load will consume a constant power, as shown
below. If input voltage rises, the input current decreases and power P (= V * I)
