Display Control
For security reasons or for a slight increase in scanning rates, you may
want to turn off the front-panel display. From the remote interface,
you can also display a 13-character message on the front-display.
You can only disable the front-panel display by sending a command
from the remote interface (you cannot disable the front panel while in
local operation).
When disabled, the entire front-panel display goes blank and all
display annunciators except
ERROR are disabled. All keys except
are locked out when the display is disabled.
The display is automatically enabled when power is cycled, after a
Factory Reset (*RST command), or when you return to local by
pressing .
You can display a message on the front panel by sending a command
from the remote interface. The instrument can display up to
13 characters on the front panel; if you attempt to send more than
13 characters, an error is generated. You can use letters (A-Z),
numbers (0-9), and special characters like “
@”, “%”, “
*
”, etc. Use the
#” character to display a degree symbol ( ° ). Commas, periods, and
semicolons share a display space with the preceding character, and
are not considered individual characters. While a message is
displayed on the front panel, readings from a scan or monitor 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.
Remote Interface Operation: The following command turns off the
front panel display.
DISPLAY OFF
The following command displays a message on the front panel and
turns on the display if disabled.
DISP:TEXT ’SCANNING ...’

the display state), send the following command.
