 PURPOSE

To set user protection levels that restrict access to certain functions and to edit the

password required for changing user levels.

 PRINCIPLE

MFC-CB’s front panel user interface provides the means to access all MFC-CB user

defined data, settings and functions including calibration data.

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 MFC-CB 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 MFC-CB settings.
