3. Perform this test for both the display assembly and the DC power supply.
Powered Leakage
Test the display assembly and external DC power supply leakage:
1. Attach the ground wire to the metal rear panel of the display assembly.
2. Plug the leakage analyzer into an AC power source. Plug the display assembly into the
analyzer’s AC receptacle.
3. Verify that leakage current from the display assembly case or DC power supply to module
housing to ground meets, or is lower than, the values provided in Table 2.
Monitor Functional Tests
This procedure verifies operation of the Ethernet port, patient data logger, remote alarm, and
external SDLC options. It assumes that an Integrated Multi-parameter module, 90470, is available
for testing purposes. In the event that the module is not available, similar modules may be
substituted for verifying specific parameters.
Required Tools/Test Equipment
• Waveform simulator and appropriate patient cable
• If patient data logger option is to be tested: terminal or computer with VT100 emulator and
appropriate standard PC cable to connect it to the properly configured DB9 serial port on the
monitor
• Module housing (for 90363)
!
• When testing the DC power supply, be sure to measure from the most distant
module housing.
