Leakage Current “Measurement Device” (MD) Characteristics
To perform the leakage current measurements, the unit under test (UUT) or device under test (DUT) has to be separated
from any interconnection to a system. If the UUT is part of a system, extended tests according to IEC 60601-1-1 have to
be performed. The figure above shows the Measuring Device (MD) circuit required for leakage current. The reading in mV
corresponds to µA (leakage current). The Safety Testers generally work with this MD circuit and the displayed values are
already converted to leakage current.
Tests
The “Electrical Safety” tests may be performed under normal ambient conditions of temperature, humidity and pressure
and line voltage. Use test “Devices” or “Measuring Devices” as shown or equivalent.
Visual Inspection
Verify instrument and accessories to ensure that;
•
Fuse links have the rating proclaimed by the manufacturer
•
Safety labels and inscriptions on the device are clearly legible
•
The mechanical condition will allow the device to be put to further use
•
Any soiling has no effect on safety of operation.
The defibrillator electrodes as well as handles and holder recesses must be free of any cream residue.
The defibrillator electrodes, pacemaker cable, ECG cable, SPO
2
cable and Responder 2000 power cord should be
checked for any visible external damage to the insulation and strain relief.
