•Afterwards leave alligator clip at test item 4) or attach the alligator clip to the test
item with the lowest resistance.
2.2 Enclosure Leakage Current (Chassis Leakage Testing)
•Press the gray "LEAKAGE" key, leaving all other selections from the previous test
the same.
•Switch on Incubator and allow the unit to complete the self-test.
•Switch on humidity module.
•Set air temperature and humidity higher than measured values.
•Set up the Biotek 501 Pro for the following tests by using the white keys labeled
"Ground", "Neutral" and "Polarity".
•Note: If the corresponding red LEDs for Ground, Neutral, and Polarity are not lit,
they are in the normal position.
•This is a measurement of the leakage current from the Chassis to earth ground.
•Activate height adjustment (if available) during the following tests.
•Maximum allowable test values under Normal Condition:
Normal Ground, Normal Polarity, Normal Neutral: 100 µA
Normal Ground, Reverse Polarity, Normal Neutral: 100 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, 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)
