2.8 Enclosure (Touch) leakage current test

Perform this test to measure current leakage through exposed conductive surfaces on the
device under test during normal operation. Refer to the instructions contained with the safety
analyzer to perform enclosure leakage current test.
DMM
NOTE: The MD represents the network and voltage measuring instrument and its frequency
characteristics per IEC 60601-1.
(1) Configure leakage tester as follows:
•
•
•
(2) Power on device under test.
(3) Read and record the current leakage indicated on tester.
NOTE: Center-tapped and non-center-tapped supply circuits produce different leakage
currents and the UL and IEC limits are different.
(4) Change leakage tester switches to:
•
•
•
(5) Read and record the current leakage indicated on the tester.
(6) Change leakage tester switches to:
•
•
•
(7) Read and record the current leakage indicated on the tester.
(8) Change leakage tester switches to:
•
•
