Electrical safety tests
General
Electrical safety tests provide a method of determining if potential
electrical health hazards to the patient or operator of the device exist.
Recommendations
Qualified personnel must perform all safety tests presented in this
chapter:

Upon receipt of the device (patient monitor and its associated
equipment). Refer to
“Dash installation checkout procedure” on
page 3-8 for more information.

Every 12 months thereafter (Preventive Maintenance). Refer to
“Maintenance schedule” on page 5-2 for more information.

Each time the main enclosure is disassembled or a circuit board is
removed, tested, repaired, or replaced (Corrective Maintenance).
Refer to
“Recommended checkout” on page 7-52 for more information.
GE recommends that the qualified personnel performing the tests should
record the values of each required electrical safety test in the
“Checklist”
on page D-1.
These instructions are intended for every component in the system.
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.
