Display Control
To speed up your measurement rate, or for security reasons, you may
want to turn off the front-panel display. From the remote interface, you
can also display a 12-character message on the front panel.
• When the display is turned off, readings are not sent to the display
and all display annunciators except
ERROR and Shift are disabled.
Front-panel operation is otherwise unaffected by turning off the display.
• The display state is stored in volatile memory; the display is enabled
when power has been off or after a remote interface reset.
• You can display a message on the front panel by sending a
command from the remote interface. The multimeter can display up
to 12 characters of the message on the front panel; any additional
characters are truncated. Commas, periods, and semicolons share a
display space with the preceding character, and are not considered
individual characters. When a message is displayed, readings are not
sent to the display.
• Sending a message to the display from the remote interface overrides
the display state; this means that you can display a message even if
the display is turned off.
• Front-Panel Operation:
5: DISPLAY (SYS MENU)
The display always turns on for menu operation; this means that
even when the display is turned off, you can still operate the menu.
• Remote Interface Operation:
DISPlay {OFF|ON} disable/enable the display
DISPlay:TEXT < quoted string > display the string enclosed in quotes
DISPlay:TEXT:CLEar clear the displayed message
The following command string shows how to display a message on the
front panel.
"DISP:TEXT ’HELLO’"
