Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual
8-10 3700S-901-01 Rev. C / July 2008
The ICL 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())
Front panel scanning
After channels have been added to the scan list, press the SCAN key to display
the SCAN ACTION MENU. If no scan list exists, pressing the SCAN key will
briefly display "No Scan List. Use INSERT to add selection."
The menu contains the following items:
BACKGROUND: Runs scan list in the background
CREATE: Displays Use <INSERT> key (reserved for future enhancements)
LIST: Displays the current scan list steps. Turn the navigation wheel to
scroll through the list.
CLEAR: Clears the existing scan list.
RESET: Resets the unit's scan aspects, which include scan count, clearing
the scan list, and scan stimulus settings like scan trigger arm.
Press the INSERT key to add the selected channels or pattern to the existing
scan list.
Press the DELETE key to remove the selected channels or pattern from the
existing scan list. Only the first occurrence of the selected item will be removed.
For example, if Channel 3003 appears in the list three times and Channel 3003
is selected when the DELETE key is pushed, the first step using Channel 3003
will be removed (the remaining two will stay in the list).
