Set to C.V. Priority Mode 
When setting the power supply to constant voltage mode, a current 
limit must also be set to determine the crossover point. When the 
current exceeds the crossover point, the mode switches to C.C. 
mode. For details about C.V. operation, see page 24. C.C. and C.V. 
mode have two selectable slew rates: High Speed Priority and Slew 
Rate Priority. High Speed Priority will use the fastest slew rate for 
the instrument while Slew Rate Priority will use a user-configured 
slew rate. 
 
Before setting the power supply to C.V. mode,

  The output is off. 
  The load is connected.
