Output Setting and Operation Commands
This section describes low-level commands used to program the power supply.
Although the
APPLy
command provides the most straightforward method to
program the power supply, the low-level output setting commands give you
more flexibility to change the individual parameters.
CURRent{<current>|MINimum | MAXimum|UP|DOWN}
This command programs the immediate current level of the power supply. The
immediate level is the current value of the output terminals.
The
CURRent
command changes the output of the power supply to the newly
programmed value regardless of the output range presently selected.
You can substitute ‘‘
MINimum
’’ or ‘‘
MAXimum
’’ in place of a specific value for
the current parameter.
MIN
selects the lowest current values of ‘‘0’’ amps.
MAX
selects the highest current values allowed for the selected range.
This command also increases or decreases the immediate current level using
the ‘‘
UP
’’ or ‘‘
DOWN
’’ parameter by a predetermined amount. The command
CURRent
:
STEP
sets the amount of increase or decrease. Notice that a new
increment setting will cause an execution error -222 (Data out of range) when
the maximum or the minimum rated current is exceeded.
CURRent
The following program segments show how to use the
CURR
