b. The FHR1 heartbeat indicator (
c. The recorder prints the heart rate tracing corresponding to the rate and the trace is plain black.
7. Hold the ultrasound transducer connected to US2 input in your hand with the transducer front facing
the palm of your hand and use your other hand to gently press and depress the back of the transducer
rhythmically while maintaining a steady rate. Confirm the following:
a. The FHR2 value responds to the rubbing.

3.3.6 NIBP Calibration Check

This procedure provides instruction to verify the accuracy of the NIBP circuitry, perform calibration if
necessary, and check the NIBP pneumatic circuit plumbing for leaks. Refer to section 4.4.1 for detailed
information.

3.3.7 Electrical Safety Tests

This section provides instructions to check if potential electrical health hazards to the patient or the operator of
the monitor unit exist.
Use an electrical safety analyzer and follow the operating instructions supplied by the manufacturer of the
safety analyzer to set up and perform the electrical safety tests.
NOTE: For reliable leakage current checks, perform the Ground Resistance Check first.
3.3.7.1 Power Outlet Check
This procedure checks the condition of the power outlet (wall outlet) from which the monitor gets power to
ensure correct results from leakage tests. Use a multimeter to ensure the power outlet is wired properly. If
other than normal polarity and ground is indicated, corrective action must be taken before proceeding. The
results of the following tests will be meaningless unless a properly wired power outlet is used.
3.3.7.2 Ground Resistance Check
Perform this check on the monitor unit only, with no other equipment (peripherals) attached.
1. Connect the monitor power cord to the safety analyzer.
2. Verify that the AC power cord of the safety analyzer is plugged into an appropriate wall outlet.
