PURPOSE
To set user protection levels that restrict access to certain functions and to edit the
password required for changing user levels.
PRINCIPLE
molbox RFM’s front panel user interface provides the means to access all molbox RFM
u s e r d e f i n e d d a t a , s e t t i n g s a n d f u n c t i o n s i n c l u d i n g c a l i b r a t i o n d a t a .
Inadvertent, uninformed or unauthorized altering or deleting of data, settings and
functions could require extensive reconfiguration by the user and might cause invalid
readings. For these reasons, depending upon the application in which molbox RFM is
being used, it may be desirable to restrict access to certain functions. The USER LEVEL
function makes this possible. Four different levels of security are available:
none
,
low
,
medium
and
high
.
Access to changing security levels can be left open, or be protected by a password so
that security levels can be used as a convenient way to avoid accidental changing of data
or as a secured means of preventing tampering with molbox RFM settings.
3.6.2.1
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 and other settings that affect
measurement integrity.
Low
Low security is designed to protect the specific metrological information
and SYSTEM DIAGNOSTIC AND MAINTENANCE functions of the
system 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 specific metrological information
in the system and to assure that the molbox RFM is operated using
consistent operational parameters.
High
High security protects all operating parameters. It is intended to
minimize operator choices (e.g., to perform repeated identical tests
under consistent conditions).
molbox RFM 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).
