n Introducing fibres or other particles into the test

vessel will result in erroneous breakdown values. A
small volume of a test sample can be used to rinse out
remnants of old oil

n If there is any damage to the test vessel, chamber or

lid, the instrument should be repaired by a Megger
authorised repair facility
