10.6.5.1 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 meter is connected to parts of the equipment, easily contacted by the user or patient.
Record the highest reading.
10.6.5.2 Generic Procedure
The test verifies the isolation of the power line from the chassis. The testing meter is connected from
accessible metal parts of the case to ground. Measurements should be made under the test conditions
specified in:
•
•
Record the highest reading of current.
1.
Connect the Safety analyzer to an AC wall outlet.
2.
Plug the equipment under test into the receptacle on the panel of the meter.
3.
Connect the meter to an accessible metal surface (see:
) of the Voluson E-Series using the
cable provided with the meter.
4.
Select the "Chassis" or "Enclosure Leakage" function on the meter.
5.
Test opening and closing the ground with the Voluson E-Series system on and off.
