4) Connect the black then white test leads to the hipot tester as indicated
5) Connect the UUT’s power supply to the UUT as indicated.
6) Connect the modified Masimo cable to the UUT as indicated.
7) Connect the black alligator clip to the UUT’s Exhaust Fitting not on the holes as indicated.
8) Connect the red alligator clip to the modified Masimo cable as indicated.
9) Turn the POWER switch ON.
10) Set the HiPot tester as follows: Voltage = 5.00kV, Current = 50uA, Duration = 0.5 sec.
11) Press the green TEST button. The HIGH VOLTAGE ON indicator flashes during the test.
12) If the UUT passes the test, the tester will beep and display the results.
13) If there is a failure, the tester will alarm and the red failure indicator will light up. To stop the alarm press the red RESET button. Record the failure on the DHR and apply a
rejected tag identifying the non conformity after completing steps 13. Place UUT into the NCM area.
14) Turn the POWER switch OFF.
15) Disconnect black test lead from exhaust port and connect to power supply plug ground repeat above starting at step 8.
16) Disconnect the Masimo cable from the UUT.
17) Disconnect the black alligator clip from the power supply plug ground.
18) If there are more units to test, go to step 4.
19) If there are no more units to test, disconnect the white then black test leads from the hypot tester.
