Model DMM7510 7½ Digit Multimeter Application Manual Section 5: Grading and binning resistors
DMM7510-904-01 Rev. D March 2021 5-5
Using SCPI commands
This sequence of SCPI commands grades resistors into bins based on the measured accuracy.
You may need to make changes so that this code will run in your programming environment.
Send the commands in the following tables to setup and run this example application.

▪
Reset the DMM7510 to default settings
▪
Make a buffer named
bufferVar
with a
capacity of 1,000,000 readings
▪
Set instrument to measure 4-wire resistance
▪
Set the number of power line cycles (NPLC)
to 1
▪
Enable autozero 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
