 Reset the DMM6500
 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
 Immediately update autozero reference measurements and then disable the autozero function
 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
 Wait for the trigger model to complete
 Display "Test Completed" when the binning test is complete
 Set the front-panel display to the USER swipe screen
