Format Subsystem - Keithley 2302 Instruction Manual

11-4 DISPlay, FORMat, and SYSTem
DISPlay:TEXT:DATA <a>
:DISPlay[:WINDow[1]]:TEXT:DATA <a>
Parameters
This command defines a text message for the display. A message is made up of 32 characters
and starts on the top line of the display and wraps down to the bottom line. Spaces are counted
as characters and can be used to properly position the message on the display. If your message
is less than 32 characters, the appropriate number of spaces are added at the end. If your message
is greater than 32 characters, it will not be displayed. On power-up, the message is a string of 32
spaces.
An indefinite block message must be the only command in the program message or the last
command in the program message. If you include a command after an indefinite block message
(on the same line), it will be treated as part of the message and is displayed instead of executed.
NOTE
DISPlay:TEXT:STATe <b>
:DISPlay[:WINDow[1]]:TEXT:STATe <b>
Parameters
This command enables or disables the text message mode. When enabled, the text message
is displayed. If no message is defined, a string of 32 spaces is displayed. When disabled, the
message is removed from display. The display returns to the normal display state.
A text message remains displayed only as long as the instrument is in remote. Taking the
instrument out of remote (by pressing the LOCAL key or sending GTL) cancels the message and
disables the text message mode.
