Delete non volatile ram deletes all entries stored in the non volatile ram of the CMU. This memory contains particular settings of the last CMU session that can be reused in the next session (e.g. the last active function group and measurement menu, special configuration etc.).
Deleting the non volatile ram can be useful after an abnormal termination of a CMU measurement session.
Note: The settings stored in the non volatile ram can also be written to a configuration file and reused in later sessions; see Chapter 3, section Saving Configurations.
