Agilent Technologies 664xA Manuale Utente

 
 Switches the display between its normal metering mode and a mode in which it displays text sent by the user.  The command
uses the character data <CRD> format.
 
 

 

 

 

DISP:MODE NORM      DISPLAY:MODE NORMAL

 

 

 

<CRD>   NORMAL or TEXT

 

 
 Allows character strings to be sent to display.  The characters will be displayed when the display mode is TEXT.  The LCD
has the following character set:
 

 LCD Character Set

 uppercase letters

 A through Z (Case-sensitive entry)

 digits

 0 through 9

 punctuation

 _  |  “  $  < >  +  -  /  =  ?  .  :  ,

 blank space

 

 
 A display is capable of showing up to 12 characters.  However, the three punctuation characters do not count toward the 12-
character limit when they are preceded by an alphanumeric character.  When punctuation characters are included, then the
maximum number of characters (alphanumeric + punctuation) that can be displayed is 15.  If it exceeds the display capacity,
a message will be truncated to fit and no error message will be generated.  If any character in the message is not a member
of the above character set, the character will not be rejected but will be displayed as a "starburst" (all 16 segments of the
character will light).
