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. 
  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. 
Operation steps 
1.  Press [CR] key and [Shift] +[CV] to enter parameter setting screen. 
Constant   Resistance 
Range=7500.0Ω 
2.  Set maximum working resistance value and press [Enter] for confirmation. 
Constant   Resistance 
Range=2000.0Ω 
3.  Set maximum voltage value and press [Enter] key. 
Constant   Resistance 
High=130.0V 
4.  Set minimum voltage value and press [Enter] key. 
Constant   Resistance 
Low=0.000V 
5.  Complete parameter setting. 
10.0000V   0.0000A 
0.00W          CC=2.000Ω 
 
NOTE 
If the above method is for editing auto test step (as mentioned below), constant 
resistance range can also be set.
