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
calibration information and other settings that affect
measurement integrity.
Low
Low security is designed to protect system calibration information and
system diagnostic and maintenance functions against
accidental alteration. It is intended for an advanced operator performing
many different tasks. Low security is the default user level setting.
Medium
Medium security is designed to protect system calibration information and
to assure that the MFC-CB is operated with consistent operational parameters.
High
High security protects all operating parameters. It is intended to minimize
operator choices (e.g., to operate in a single, inalterable configuration).
MFC-CB is delivered with the security level set to low to avoid inadvertent altering of
critical internal settings but with unrestricted access to changing security
level
setting. It is recommended that the low security level be maintained at all times
and password protection be implemented if control over setting of security levels
is desired.
If there is a risk of unauthorized changing of the security level, changing authority
should be password protected (see OPERATION of this section).
The High security level disables remote communications and returns an error
message (“ERROR”) to all remote commands. All other security levels have NO effect
on remote communications.
The security levels are structured to support typical levels of operation.
Specifically, the security levels
prevent
execution of the functions accessed by the
keystrokes marked by “
