Set to C.C. Mode
When setting the power supply to constant current mode, a voltage
limit must also be set to determine the crossover point. When the
voltage exceeds the crossover point, the mode switches to C.V.
mode. For details about C.C. operation, see page 22. 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.
