Descriptions

Create a variable to hold the scan
count


scanned data every two seconds


state

Set the buffer size (not necessary
when using the default buffer, but
added to show command use
case)


Set the channels ranges to auto

Set NPLC to 5

Set autozero function to ON

Setup the scan list

Setup the number of repeated
scans

Initiate the scan

Delay two seconds to allow
readings to accumulate

