Application — sorting resistors
For this application, the idea is to sort a batch of 100Ω resistors into three bins. Bin 1 is for
resistors that are within 1% of the nominal value. Bin 2 is for resistors that exceed 1%
tolerance, but are within 5%. Bin 3 is for resistors that exceed 5% tolerance.
The digital outputs of the Model 2700 can be used to further automate the test system by
controlling a compatible component handler to perform the binning operations.
Limits
Limit testing is used to test resistor tolerances. Figure 9-6 shows a basic setup using 4-wire
offset-compensated ohms to test 100Ω resistors.
