8.5 Performance
Verification
Procedures
When running a complete performance verification, perform the tests in order
to ensure logical fault diagnosis. If the ventilator fails any performance
verification test, see section 8.7, Performance Verification Troubleshooting/
Repair for troubleshooting instructions. Fill in the applicable parts of the
Performance Verification Data Form as each test is completed.
8.5.1 Electrical Safety (Test 1)
The electrical safety test verifies that the ground resistance and forward and
reverse leakage current are within specified limits (Figure 8-10).
Required equipment:
• 0.25-in. test adapter
• Needle nose vise grips
• Electrical safety analyzer
1. Check that the ground resistance < 0.2 ohm (Ω) at these test points:
• Gas outlet port
• Proximal pressure port
• Oxygen fitting retention plate
2. Attach the 0.25-in. test adapter to the gas outlet port.
3. Turn the ventilator on and check that the cooling fan is operating
correctly.
4. Check that the forward and reverse leakage current is:
• < 300 microamperes (µA) for ventilators connected to
100-120 VAC/60 Hz.
• < 500 µA for ventilators connected to 220-240 VAC/50 Hz.
5. The electrical safety test is complete.
