Before attempting any programming, it is best to set the instrument to a known
state. The following command grouping illustrates how to reset the instrument.

information on issuing a device clear, since the device clear command is specific
to the interface you are using. Perform the following steps:
1 Issue an Interface Clear and a Device Clear. (See your computer or interface
