7. Measure the voltage at U4-pin2 to COM, which should be +1.0V, +/-
100mV.
8. Measure the voltage at U4-pin3 to COM, which should be 0V.
9. Measure the voltage at U4-pin7 to COM, which should be +3.6V, +/-
100mV.
10. Verify that the OT1 LED is off.
11. Measure TP7 to TP3, which should be 0V.
12. Measure TP9 to TP3, which should be +5.0V, +/- 250mV.
13. Measure TP8 to TP3, which should be 0V.
14. Measure TP1 to TP2, which should be 0V.
15. Connect a jumper between TB3-1 and TB3-2 and verify that the voltage
at TP6 is +2.2V, +/-100mV.
16. Apply a 60Hz, 33% duty cycle signal to the OP1 fiber optic input.
17. Verify that the diagnostics transmitter LED, OT1, is on.
18. Verify that the signals at TP9 and TP8 are as shown in
Figure 60 on
page 83 .
19. Verify that the signal between TP1 and TP2 is as shown in
Figure 61 on
page 84 and Figure 62 on page 84
20. Remove the jumper between TB3-1 and TB3-2.
21. Apply a constant fiber optic signal to the OP1 input.
