7.2.6 Testing US Transducers

To test a US transducer:
1 Switch on the monitor.
2 Connect the US transducer to the fetal monitor.
3 Hold the transducer with one hand, and gently touch the center of the transducer with the
other hand in the frequency of 2 times per second.
4 Check that the value on the display shows this change in FHR.
If a US transducer fails the test, repeat this test with another transducer. If the second one passes
the test, defect of the first transducer is confirmed. Replace it with a good one. If the second
transducer fails the test as well, contact the manufacturer for service.
