If the devices in the medical electrical system are connected to a multiple portable socket outlet, the
resulting protective earth leakage current needs to be determined. All system components must be
connected to the multiple portable socket outlet and be switched on during this measurement.
Refer to the documentation that accompanies the safety analyzer for further details on how to set up
the test.
Preventive Maintenance Procedures
The preventive maintenance tasks are restricted to the noninvasive blood pressure measurement
calibration. Carry out the noninvasive blood pressure measurement performance tests at least every
two years, or as specified by local laws (whichever comes first).
Noninvasive Blood Pressure Measurement Calibration
Carry out the noninvasive blood pressure measurement performance tests at least every two years, or
as specified by local laws (whichever comes first).
Tympanic Temperature Calibration
To verify the performance of the Tympanic Thermometer:
1 Purchase a Covidien calibration device, part number 303097. See the Covidien web site for
ordering information (www.covidien.com).
2 Follow the instructions provided with the calibration device to perform the test.
NOTE
The battery compartment in the Tympanic temperature probe is not functional.
CAUTION
After performing the calibration, check the body reference site selection of the Tympanic
Thermometer to make sure it matches the required settings for your hospital.
Fetal Recorder Maintenance
The recorder rubber roller, thermal printhead, and paper sensor should be cleaned at least once a year,
or when needed (when traces become faint).
Clean the assemblies as follows:
•
Clean the recorder rubber roller with a lint-free cloth using a soap/water solution.
• Wipe the printhead using a cotton swab moistened with 70% Isopropyl alcohol based solution.
• Check the paper sensing mechanism is dust free.
