Performing a Scan
Once you set up a scan list and configure the scan, the actual scan can be
performed.
•
If a scan list contains a non-existing channel, the scan cannot be
performed and an error will occur.
•
If a scan list contains a channel on a digital I/O module that does not
work in Mode #1 or Mode #2, the scan cannot be performed and an
error will occur (see page 98 for more information about modes).
•
If a stored channel setup in the scan list does not match the current
hardware configuration, the scan cannot be performed and an error
will occur.
•
Front-Panel Operation: Press Scan to begin the scan operation. If you
have set the arm source and trigger source to IMMediate, the scan
will begin when the key is pressed. If you have configured other arm
or trigger sources, the scan will begin when the source criteria are
met.
Stop a scan in progress by pressing Shift+Scan. The last channel
closed in the scan list will remain closed. You cannot pause and then
continue a scan. You must start the scan operation over.
Press Step to start and step through the channels in the scan list, one
channel at a time.
•
Remote Interface Operation: Use the commands shown below to begin
a scan or stop a scan in progress. If you abort a scan in progress, the
last channel closed in the scan list will remain closed. You cannot
pause and then continue a scan. You must start the scan operation
over.
The
INITiate
command moves the instrument from the idle state to
the arm layer. The arm source and trigger source will control the
actual beginning of the scan.
