Chassis leakage current test
Definition
This test, also known as Enclosure Leakage current test,
measures the current that would flow through a grounded
person who touches the accessible conductive parts of the
equipment during normal and fault conditions.
The test verifies the isolation of the power line from the chassis.
The testing Electrical Safety Analyzer is connected to parts of
the equipment, easily contacted by the user or patient.
Record the highest reading.
DANGER Electric Shock Hazard.
When the Electrical Safety Analyzer's ground switch is OPEN, DO NOT
touch the Ultrasound system!
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.
