Visual Inspection
Before Each Use
Check all exterior housings for cracks and damage. Check the condition of all external cables,
especially for splits or cracks, and signs of twisting. If serious damage is evident, the cable should be
replaced immediately. On the Toco
+
transducer and the patient module, ensure that the adapter cable
socket is not damaged. Check that all mountings are correctly installed and secure. Refer to the
instructions that accompany the relevant mounting solution.
After Each Service, Maintenance or Repair Event
Ensure all fuses accessible from the outside comply with the manufacturer’s specification.
Check:
•
the integrity of mechanical parts, internally and externally.
• any damage or contamination, internally and externally.
• that no loose parts or foreign bodies remain in the device after servicing or repair.
• the integrity of all relevant accessories.
Power On Test
1
Connect the monitoring system to mains and switch on the monitor.
2
Make sure that the green LED lights up and switches off again, and the display comes up.
The expected test result: the monitor boots up and display comes up.
Safety Tests
Safety tests are comprised of the following tests performed on the monitoring system:
•
detachable power cord protective earth resistance (optional)
• equipment leakage current
• applied part leakage current
• system test (if required)
Safety test requirements are set according to international standards, their national deviations and
specific local requirements. The safety tests detailed in this Service Guide are derived from
international standards, but may not be sufficient to meet local requirements. We recommend that you
file the results of safety tests. This may help to identify a problem early, particularly if the test results
deteriorate over a period of time.
Each individual piece of equipment of the monitoring system, which has its own connection to mains,
or which can be connected or disconnected from mains without the use of a tool, must be tested
individually. The monitoring system as a whole must be tested according to the System Test procedure.
Accessories of the monitoring system which can affect the safety of the equipment under test, or the
results of the safety test, must be included in the tests and documented.
