Examples:
:APPLy DEF, MAX
You can use DEF, MIN or MAX to replace voltage value < Voltage > or
current value .
1) When select DEF, the voltage value is at 0, and the current value is at
20A(PSM-2010). Please refer to Table1-1, Table1-2 and Table1-3.
2) When select MIN, both values of voltage and current are at 0.
3) When select MAX, both values of voltage and current can be set at the
maximum value of the selected range. Please refer to Table1-1, Table1-
2 and Table1-3.
4) If only one parameter is specified, the power supply will regard it as
voltage value.
Ex :APPLy 2.0
5) :APPLy ? This command returns present voltage and current setting
values.
