By read access the device provides information about its restore capability.
Bit 0 = 1, the device restores parameters only on command. That means, if
parameters have been changed by the user and "Restore Parameter Command" had
been executed, at the next power on, the parameters will have the values of factory
setting.
In case of write access the device stores the parameters to the non volatile memory.
This procedure takes approx. 3s. In this time the measuring system isn't accessible
at the bus.
In order to avoid restore of parameters by mistake, restore is only executed when a
specific signature is written to the object. The signature is "load".

On reception of the correct signature, the device restores the parameters. If the
restoring failed, the device responds with abort domain transfer, error class 6, error
code 6 (hardware fault). See also object 6503h.
If a wrong signature is written, the device refuses to restore and responds with abort
domain transfer, error class 8, error code 0.
