Electrical Safety Analyzer

Walks through the Class I/II, Type B/BF/CF leakage-current test structure - Normal Condition vs Single Fault Condition - with a measured-vs-limit meter for each test.

What a BMET verifies with this

-Protective earth resistance
-Enclosure and patient (applied-part) leakage current, normal and single-fault
-Whether the device class and applied-part type change which limit applies
