At Power-On and after a reset command (“*RST”), the front
panel display is turned on. The front panel will display the
message:
Standby
if the AC line power switch is off. If the AC line power switch is
on, the front panel will display the message:
System OK
These two messages are displayed only when no out-of-
tolerance conditions have been detected by the EMS. If an out-
of-tolerance condition is detected, a status message is
displayed. Consult the “Front Panel Display Status Messages”
of this chapter for a description of the various status messages
and their meanings.
Turning The
Display On and Off
At Power-On and after a reset, the front panel display is turned
on. The front panel may be turned off using the command:
DISPLAY:TEXT:STATE OFF
After this command is executed, the display is turned off. The
display will not display any status messages nor will it display
any user-defined messages.
The front panel display may be turned on by using the
command:
DISPLAY:TEXT:STATE ON
The present state of the display may be read using the query:
DISPLAY:TEXT:STATE?
The EMS will reply to this query with a “0" if the display is off, or
a “1" if the display is on.
Writing a Message
To The Display
The user may write a message to the display. This is done with
the command:
DISPLAY:TEXT “Show This On The Display”
This text to display may be enclosed in either double quotes or in
single quotes.
The text message may be from 0 to 80 characters in length.
