SECURITY CODE SETTING MODE
General notes
The instrument parameters are divided in two families and
each family is divided in groups.
- The first family encompasses all the run time parameters.
- The second family comprises all the configuration
parameters.
A specific security code enables the parameter modification of
each family.
For run time parameters, it is possible to select which groups
of them will be protected by the security code and in this case
it is necessary to set the run time security code before to
modify one or more parameters of a protected group.
The configuration security code protects all configuration
parameters and it will be necessary to set the configuration
security code before to start the configuration parameters
modification.
For configuration parameters an hardware lock is also
available.
