C. Test

NOTE: One of these two tools is necessary for this test: the 99D24003000001 PLUG-ELECTRICAL TEST or the VOLTMETER - TRUE RMS AC VOLTAGE MEASURING.

(1) For the test with the 99D24003000001 PLUG-ELECTRICAL TEST:
(a) On CAPT hand-microphone panel 17VU:
1 Connect the 99D24003000001 PLUG-ELECTRICAL TEST to the CAPT outlet (5NA).
2 On the 99D24003000001 PLUG-ELECTRICAL TEST, push the pushbutton switch. A light comes on.
3 Connect the voltmeter to the 99D24003000001 PLUG-ELECTRICAL TEST and make sure that the voltage is 115VAC.
4 Disconnect the voltmeter from the 99D24003000001 PLUG-ELECTRICAL TEST.
5 Release the pushbutton switch. The light goes off.
6 Disconnect the 99D24003000001 PLUG-ELECTRICAL TEST from the CAPT outlet (5NA).
(b) On F/O hand-microphone panel 16VU:
1 Connect the 99D24003000001 PLUG-ELECTRICAL TEST to the F/O outlet (4NA).
2 On the 99D24003000001 PLUG-ELECTRICAL TEST, push the pushbutton switch. A light comes on.
3 Connect the voltmeter to the 99D24003000001 PLUG-ELECTRICAL TEST and make sure that the voltage is 115VAC.
4 Disconnect the voltmeter from the 99D24003000001 PLUG-ELECTRICAL TEST.
5 Release the pushbutton switch. The light goes off.
6 Disconnect the 99D24003000001 PLUG-ELECTRICAL TEST from the F/O outlet (4NA).
(2) For the test with the VOLTMETER - TRUE RMS AC VOLTAGE MEASURING:
(a) Do the next steps for the CAPT outlet:
1 On panel 121VU, open circuit breaker PILOTS OUTLETS 2NA.
2 On CAPT hand-microphone panel 17VU, connect the VOLTMETER - TRUE RMS AC VOLTAGE MEASURING to the CAPT outlet (5NA).
3 On panel 121VU, close circuit breaker PILOTS OUTLETS 2NA.
4 Make sure that the voltage is 115VAC.
5 On panel 121VU, open circuit breaker PILOTS OUTLETS 2NA.
6 Disconnect the VOLTMETER - TRUE RMS AC VOLTAGE MEASURING from the CAPT outlet (5NA).
7 On panel 121VU, close circuit breaker PILOTS OUTLETS 2NA.
(b) Do the next steps for the F/O outlet:
1 On panel 121VU, open circuit breaker PILOTS OUTLETS 2NA.
2 On F/O hand-microphone panel 16VU, connect the VOLTMETER - TRUE RMS AC VOLTAGE MEASURING to the F/O outlet (4NA).
3 On panel 121VU, close circuit breaker PILOTS OUTLETS 2NA.
4 Make sure that the voltage is 115VAC.
5 On panel 121VU, open circuit breaker PILOTS OUTLETS 2NA.
6 Disconnect the VOLTMETER - TRUE RMS AC VOLTAGE MEASURING from the F/O outlet (4NA).
7 On panel 121VU, close circuit breaker PILOTS OUTLETS 2NA.
