• Reset the Model DMM7510 to default settings
• Make a buffer named bufferVar with a
capacity of 1,000,000 readings
• Clear bufferVar
• Set instrument to measure 4-wire resistance
• Set the number of power line cycles (NPLC)
to 1
• Enable auto zero once
• Enable offset compensation for more accurate
resistance readings
• Configure digital I/O lines 1 through 4 as
digital outputs; these are used to output
binning code to the component handler
• Set the states of digital I/O lines 1 through 4
to bit low
• Configure digital I/O line 5 as trigger input to
detect start-of-test trigger
• Set trigger detector to detect falling edge on
digital I/O line 5
• Configure digital I/O line 6 as a trigger output
used to send end-of-test trigger with negative
logic and output pulse width of 10 µs.
• The trigger pulse occurs when the Notify block
generates an event
• Define the GradeBinning trigger model
template
• Initiate the trigger model
• Set the front-panel display to the USER swipe
screen
• Display "Test Completed" when the binning
test is complete
