Hey, I have a Megger 1553 and lent it to a friend, who is an experienced spark with 2391 and good knowledge/experience of testing. However, friend carried out PFC test using 3 leads, even though PFC should be carried out using 2 leads on this unit. Since PFC was carried out incorrectly the tester will apparently now only detect reversed polarity when trying to carry out any Zs or RCD tests. She tried 2no different socket test leads and separate leads with kewtech R1+R2 socket but still no joy. Recently calibrated, batteries replaced, and replacable fuse is fine. Anyone had a similar problem? I havent got the unit back of my friend yet and am just trying to work out and whether its completely dead from doing the test wrong or just an internal fuse that has blown? Thanks
