PRINCIPLE
PPCK+'s front panel user interface provides the means to access all PPCK+
user 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 and behavior. For these reasons, depending upon
the application in which PPCK+ is being used, it may be desirable to restrict
access to certain functions for certain users. The user level function provides a
means of restricting access to certain functions. Four different levels of security
are available.
Access to changing security levels can be left open, or be protected by
a password.
