Remarks
Regardless of which instrument state is specified, the power-down state is
automatically stored in location 0.
When shipped from the factory, storage locations 1 through 4 are empty
and the instrument is configured to automatically recall the power-down
state (location 0) when power is restored. You can change the factory
configuration such that a Factory Reset (*RST command) is issued when
power is restored.
A Factory Reset (*RST command) does not affect the configurations stored
in memory. Once a state is stored, it remains until it is overwritten or
specifically deleted.
