•
Remove the red lead with the alligator clip from the Incubator.
•
Remove the alligator clip from the red test lead and plug this end into the green
input jack "GROUND" on the back panel on the Biotek 501 Pro.
•
Leave all other selections from the previous test the same.

•
This is a measurement of the leakage current flowing through the ground wire of
the power cord.
•
Activate height adjustment (if available) during every following test.
•
Maximum allowable test values under Normal Condition:
Open Ground, Normal Polarity, Normal Neutral:
500 µA, but not 0 µA
Open Ground, Reverse Polarity, Normal Neutral:
500 µA, but not 0 µA
(According to CAN/CSA - 22.2 No. 601.1 - M90, Sub-clause 19.3, Table IV)
•
Maximum allowable test values under Single Fault Condition:
Open Ground, Normal Polarity, Open Neutral:
