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 UP or
Example
CURR DOWN command to increase or decrease the output current with the CURR:STEP
command.
‘‘CURR:STEP 0.01’’ Set the step size to 0.01 A
‘‘CURR UP’’ Increase the output current
‘‘CURR:STEP 0.02’’ Set the step size to 0.02 A
‘‘CURR DOWN’’ Decrease the output current
