Before testing the probe, the Simulator reads this resistor to determine the LED
connection being tested.
Examining the 15-pin connector further:
1. Up to two LED calibration resistors can be tested by the Simulator. Connect them as
2. The probe photodiode is to be connected to pins 9 and 10 as shown.
3. Finally, up to three shields can be tested for shorts to other leads. These would be
