If you rename a digital power supply by changing its RefDes, and there are other instances of
the same supply on the schematic, you will be prompted to confirm that you want to change
all instances of the RefDes. If you select No, only the RefDes for the selected component will
change. Remember that if a digital power supply’s RefDes is changed, the net name of any
wires attached to it will change to match the new RefDes. For a more detailed discussion, see
“Global Nets” in the Multisim User Guide, or the Multisim helpfile.
 To change the properties of a digital power supply:
1. Double-click on the component to display its properties dialog box, and click on the
Valu e
tab. Change the value in the
Voltage (V) field as desired.
2. To change the reference designator for the component, click on the
Label tab and change
the entry in the
RefDes field.
3. Click
OK to close the dialog box.
