Why Aren't All the Personality Options Loaded in Memory?

Many measurement personality options are available for use with this instrument. If the option is
loaded in the instrument, you must also have a license key entered, to use it.
Some versions of instrument hardware my not have enough memory to accommodate all the options
that you have ordered. If this is the case you will need to swap the applications in/out of memory, as
needed. It may also be possible to upgrade your hardware to have more memory. Contact your local
sales/service office.
