Description
Reset the Series 3700 to
factory defaults.
Set the configuration for
all channels in Slot 4 to
fourwireohms.
Create scan for all
channels on the card
installed in Slot 4.
Set up digital I/O line 1 to
detect a falling-edge
trigger.
Set up digital I/O line 2 to
detect a falling-edge
trigger.
Set each channel so that
it will close with a
measurement complete
event.
Set digio 2 to pulse when
a channel ready event
occurs.
Set each measurement
to occur with a digio 1
event trigger.
Set bypass to ON so first
channel closes without
taking a measurement.
Make buffer named
mybuffer and configure it
to store up to 1000
readings.
Initiate the scan to
execute in the
background and save
readings to a buffer
called mybuffer.
