Safety Testing Chapter 8 - Test and Inspection Matrix 89 System Safety Test Whenever you connect a monitor to an obstetrical system such as Agilent OB TraceVue you must perform the System Test. The System Test consists of the Enclosure Leakage Current tests (normal and single fault condition) as described on 86. You must run this test when connecting either a new or repaired monitor.

Testing Transducers 90Chapter 8 - Test and Inspection Matrix Testing Transducers Testing Toco Transducers Visual CheckCheck the transducer for signs of damage. Ensure that there are no cracks in the transducer housing or dome, in the cable or the connector plug. Electrical Check1. Turn on the monitor. 2. Connect the transducer to the Toco socket. 3. Check that the display acknowledges the connected transducer in the Toco frame of the main monitoring screen. 4. Lay the transducer face up on a flat surface for a few seconds. 5. Set the Toco Baseline as follows: a. Highlight the Toco frame in the main monitoring screen by turning the navigation wheel. b. Press the wheel to enter the Toco Menu. The existing Toco Baseline will be displayed. c. If you need to change this, highlight the TOCO Baseline menu item, and press the navigation wheel. You will see a box containing the choices for setting the Toco Baseline. d. Highlight the desired Toco Baseline value by turning the navigation wheel, and select by pressing the wheel. e. Exit the Toco menu by highlighting Return and pressing the navigation wheel. 6. Zero the Toco by pressing the button. 7. Turn the transducer over so that button is face down on the flat surface. Hold the cable at a point 25 cm from the transducer and ensure that the
Testing Transducers Chapter 8 - Test and Inspection Matrix 91 transducer touches the flat surface only with the button and that the transducer is parallel to the flat surface. 8. The Toco display should read between 20 and 40 units above the Baseline. Figure 12 Testing a Toco Transducer 9. If the test fails, repeat with another transducer. If it still fails, refer to Chapter 5,“Troubleshooting”. Toco display = 5, 10, 15, or 20 depending on Baseline setting Toco display = 20 - 40 Toco units above the Baseline
Testing Transducers 92Chapter 8 - Test and Inspection Matrix Testing Ultrasound Transducers Visual CheckCheck the transducer for signs of damage. Ensure that there are no cracks in the transducer housing or dome, in the cable or the connector plug. Electrical Check1. Turn on the monitor. 2. Connect the transducer(s) to the US 1 or US 2 socket. 3. Check that the display acknowledges the connected transducer(s) in the Ultrasound frame of the main monitoring screen. 4. Increase the loudspeaker volume to an audible level. 5. Holding the transducer in one hand, move your hand repeatedly towards and then away from the surface of the transducer, or gently tap the transducer surface with your finger. Figure 13 Testing an Ultrasound Transducer 6. Check that a noise is heard from the loudspeaker.
Testing Transducers Chapter 8 - Test and Inspection Matrix 93 7. The transducer contains seven piezo-electric crystals. Figure 14 Position Of Crystals in an Ultrasound Transducer 8. Holding the transducer in one hand, move a flat-bottomed pencil or similar object repeatedly towards and then away from each crystal. The distance between the pen and the transducer surface should be about 2 to 3 cm. Figure 15 Testing the Crystals in an Ultrasound Transducer 9. Check that a noise is heard from the loudspeaker for each crystal.
