for LCD test with 40 characters of “8”.
Function
6: User-definable message, up to 40 characters long, set from
the front panel. Enter numeric messages with the keypad.
Alphanumeric messages require the [Z7iQY] (SHIFT) key
to access the alphabetical characters (blue letters) above
the keypad. If required alphabetical characters are not
available on the front panel, send a message from an external
controller over HP-IB. Refer to “ [SOURceI : PAGing [ : FORMat]
: (POCSag I FLEX I FTD3 :MESS :DEFine ’ string”’ in Chapter 2.
MESSAGE LENGTH specifies the maximum number of characters that
will be sent out and displayed in the message field. The allowable
range is 1 to 40. After specifying the number of characters, press
[vdB(mL) (ENTER) to save the new value.
When the value of this parameter is equal to or greater than the
length of the message, the whole message will be sent out.
When the value of this parameter is less than the length of the
message, only the characters specified by this parameter are output.
(For example, if the MESSAGE NO. is 1 (0123456[Xj) and the MESSAGE
LENGTH is 5, the message which is displayed and will be sent out is
actually 01234.)
