PROGRAMMING OF MULTIRAE
4 - 3
Security Level
There are three levels of security in the MultiRAE PLUS
programming mode to provide further protection against
unauthorized changes to the monitor alarm settings and other
settings. The
level 2 security allows a user to enter
programming mode without any restriction. This is the
default security setting. The
level 1 security requires a 4
digits password to enter programming mode. Level 0
security allows a user to enter the programming mode
without any password checking, as in the level 2. However,
it does not allow a user to save any changes to the alarm
limits, real time clock, correction factor, user and site
information, etc. A user can still perform calibration with
level 0 security. The security level must be set using a PC
(see Chapter 5 for details on setting up the security level).
Once inside the programming mode, LCD will display the
first menu. Each subsequent menu item can be viewed by
pressing the
[N/-] repeatedly until the desired menu is
displayed. To enter the sub-menu of a particular menu, press
the
[Y/+] key and the sub-menu will be displayed.
To exit the programming mode and return to the normal
operation, press the
[MODE] key at any of the first tier menu
displays.
