Each device on the GPIB (IEEE-488) interface must have a unique address. You can
set the address of the 620L to any value between 0 and 30. The address can only be
set from the front panel. The address is stored in non-volatile memory and does not
change when the power has been off or after a remote reset.
The address is set to 9 when the instrument is shipped from the factory.
