greater than or equal to the programmed voltage divided by programmed current, the power
supply will operate in Voltage mode (forced).
Commanding the power supply to go into Current mode (with output disabled) from Voltage
mode causes the output relays to put an internal short across the power supply output (allowing
the load to be connected/disconnected). With the output disabled the CURRENT indicator will
go on and the VOLTAGE indicator will go off. If the output is enabled, the actual mode will be
determined by the programmed voltage and current values relative to the load (see PAR.
3.2.1.7.1). To command the power supply to enter Current mode, proceed as follows:
1. Press SHIFT key; display resembles A or B below.
