NOTE
If the above method is for editing auto test step (as mentioned below), constant
resistance range can also be set.
3.2.4 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)
will maintain at setting power. As shown in Fig. 3-4:

Under CW mode, the electronic load provides three ways to modify constant
power.
 Under CW mode, rotate the pulse knob to change constant power value.
 Under CW mode, directly input numeric key and press [Enter] key for
confirmation to change constant power value.
 Under CW mode, move the cursor with Left/Right Key and press Left/Right
Key to adjust value at corresponding position.
Operation steps
1. Press [CW] key. Press [Shift] + [CV] to enter parameter setting screen.
