If the above method is for editing auto test step (as mentioned below), constant voltage
range can also be set.
3.2.3 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.
 Under CR mode, rotate the pulse knob to change constant resistance
value.
 Under CR mode, directly input numeric key and press [Enter] key for
confirmation to change constant resistant value.
 Under CR mode, move the cursor with Left/Right Key and press Left/Right
Key to adjust value at corresponding position.
