Security Levels
The security levels are structured to support typical operating environments
as follows:
None
This level is intended for use only by the system manager and/or
calibration facility. It allows access and editing in all areas including
critical metrological information.
Low
This level of security is designed to protect the specific metrological
information and system diagnostic and maintenance functions of
the system. It is intended for an advanced operator performing many
different tasks.
Medium This level of security is designed to protect specific metrological
information in the system and to assure that the PPC2+ is operated using
consistent operational parameters.
High
This level of security is designed to protect all operating parameters. It is
intended to minimize operator choices, for example to perform repeated
identical calibrations under consistent conditions.
