2 Electrical Safety Tests
2.1 General
Electrical safety tests provide a method of determining if potential electrical health hazards to
the patient or operator of the device exist.
2.2 Recommendations
GE recommends that you perform all safety tests presented in this chapter.
• Upon receipt of the device (monitor and its associated equipment).
• Every twelve months thereafter planned maintenance
• Each time the main enclosure is disassembled or a circuit board is removed, tested,
repaired, or replaced
These instructions are intended for every component in the system. GE recommends that the
qualified personnel performing the tests.
2.3 Test Equipment
The recommended test equipment required to perform electrical safety tests is listed below.
Perform electrical safety tests using an electrical safety analyzer per IEC 60601-1, UL 60601-1,
EN 60601-1 or CSA C22.2 No. 601.1. The schematics in the section provide a general
understanding of the test equipment. Actual configuration of test equipment may vary.
The patient monitor being tested should be placed on an insulating surface.
2.4 Power Outlet Test
Verify that the power outlet is wired correctly per the countryís electrical code standard before
starting the following electrical safety tests. The results of the following tests will be inaccurate
unless a properly wired power outlet is used. Use only non-isolated power outlets when
performing safety tests.
2.5 Power cord and plug
Verify the power cord being used with the patient monitor is good. The following are a couple
of things to check for in this regard:
Item Specification
Leakage Current Tester Equivalent to the circuits
shown
Digital Multimeter (DMM) (optional based on
leakage tester used and locality)
AC volts, ohms
Ground Bond Tester 0 – 1 ohm
ECG Test Body All leads together
