NOTE
z
If all of the applied parts correspond to the instrument type, the applied parts
will be tied together and one reading will be taken. If any of the applied parts
differ from the instrument type, all applied parts will be tested individually,
based on the type of applied part. This applies to Auto and Step modes only.
In Case of Failure
„ Check any broken of the enclosure. Replace any defective part.
„ Inspect wiring for bad crimps, poor connections, or damage.
„ Test the wall outlet; verify it is grounded and is free of other wiring abnormalities.
Notify the user or owner to correct any deviations. As a work around, check the other
outlets to see if they could be used instead.
„ Change another probe to confirm if the fail is caused by console.
„ If the leakage current measurement tests fail on a new unit and if situation can not be
corrected, submit a Safety Failure Report to document the system problem. Remove unit
from operation.
„ If all else fails, stop using and inform the Customer Service Engineer for analysis and
disposal.
LIMITS
„ For CF applied parts: 50 μ A
„ For BF applied parts: 5000 μ A
