6.- SET-UP PROCEDURE
The set-up procedure of the CVM-144 is performed by means of several SET-
UP options.
For accessing the set-up menu the keys max & min must be
simultaneously pressed once the instrument is at the main screen.
When accessing the SET-UP, the message "SET-UP unlo " (1) is shown for
some seconds on screen, or, otherwise, the message "SET-UP loc" (2).
(1) Set-up UNLO (SET-UP unlocked ) : when the SET-UP is
accessed, configuration parameters can be either visualized and
modified.
(2) Set-up LOC (SET-UP locked ) : when the SET-UP is accessed,
configuration parameters can be visualized but cannot be modified .
