1. To select a fixed source range, specify the current output value that is going to be sourced. The
Model 622x will go to the lowest range that can source that value. For example, If you are going
to source 25mA, let <n> = 25e-3. The 100mA range will be selected.
2. Selecting a fixed source range disables autorange.
3. The output must be off in order change the output response. Sending this command while the
output is on will generate error -220 Execution Error.
4. OUTP OFF turns the output off, but does change the set output level. SOUR:CLE sets the out
put level to zero and then turns the output off.

Programming example

The following programming example shows a typical command sequence to con-
figure and control the DC output:

CURRent:RANGe:AUTO ON
CURRent 12e-3
CURRent:COMPliance 10
