For example, a scan list is comprised of Channels 1 to 60 on a Model 3720 card with the channels
configured to measure DC volts. Changing Channels 1 to 30 to be configured for 4-wire ohms
measurements causes the scan list to change. The scan list changes to contain Channels 1 to 30
measuring 4-wire ohms, and Channels 31 to 60 are removed because they are paired with Channels
1 to 30. If you then change Channels 1 to 60 to be configured for measuring DC volts, the scan list
will still only contain Channels 1 to 30, but it will be measuring DC volts. Channels 31 to 60 are not
automatically added back into the list.
The remote commands to simulate this example follow. Assume the Model 3720 is in Slot 3:
-- Configure Channels 1 to 60 to measure DC volts.
dmm.setconfig("slot3", "dcvolts")
-- Create a scan list, channels measuring DC volts.
scan.create("slot3")
-- View the scan list, 60 channels measuring DC volts.
print(scan.list())
-- Change Channels 1 to 30 to 4-wire ohms.
dmm.setconfig("slot3", "fourwireohms")
-- List now has Channels 1 to 30 measuring 4-wire ohms.
print(scan.list())
-- Change back to DC volts on Channels 1 to 60.
dmm.setconfig("slot3", "dcvolts")
-- List still has Channels 1 to 30, but measures DC volts.
print(scan.list())
To configure a scan from the SCAN ATTR MENU, while in an active scan list:
1. Press the CONFIG key.
2. Press the SCAN key. Modify any of the following menu items as needed:
â–ª ADD: Displays Use INSERT key. The related command is scan.add, without the optional DMM
configuration.
â–ª BYPASS: Enables (ON) or disables (OFF) bypassing the first step of the first scan pass. Related
command: scan.bypass (on page 11-314).
â–ª MODE: Sets the scan mode value to one of the following: OPEN_ALL (default setting),
OPEN_SELECT, or FIXED_ABR
Related command: scan.mode (on page 11-321).
â–ª MEAS_CNT: Sets the measure count value. Related command: scan.measurecount (on page 11-320).
â–ª SCAN_CNT: Sets the scan count value. Related command: scan.scancount (on page 11-325).
3. Press the EXIT key to leave the menu.
