Electrical safety tests
Ultrasound System – Common Service Information 4-29
Direction 5444964-100 English Rev. 5
Isolated patient lead (source) leakage–lead to ground
Definition
This test measures the current which would flow to ground from
any of the isolated ECG leads. The Electrical Safety Analyzer
simulates a patient who is connected to the monitoring
equipment and is grounded by touching some other grounded
surface.
Measurements should be made with the ground open and
closed, with power line polarity normal and reversed, and with
the Ultrasound system on and off (per IEC 62353).
For each combination the operating controls, such as the lead
switch, should be operated to find the worst case condition.
CAUTION
Equipment damage possibility.
Never switch the Polarity and the status of Neutral when the
Ultrasound system is powered ON.
Power off the Ultrasound system, allow the stored energy to
bleed down, and turn the circuit breaker off BEFORE switching
the "POLARITY" switch and/or the "NEUTRAL" switch on the
Electrical Safety Analyzer to avoid possible power supply
damage.
