Megger mft error codes

[vernam616]

Hi all

Does anyone have a list of error codes for the MFT1552?

Come across the code "E79" today and wondering what it could be

Thanks
Dan

Sorry no, they're not listed in the pdf manual. Have you tried the megger site?

Megger site isnt much use, clicked the support link and they need various details, i CBA going to the van to find the serial number out (its cold and windy outside and ive been in it all day )

Just had a peek and there's nothing in the MFT1500 series section that contains it (as far as I can see). Best drop megger technical an email.

Seems strange and i dont think its the test kit at fault either, was happily testing away in a new build plot, FULL RCBO d/b so had the 3 leads connected doing the earth loops on "No Trip" got to the heating circuit, polarity correct etc... and E79 error pops up instead of the reading!

Borrowed another test kit, identical one infact and that issued the same error E79, ran out of time tonight so will have a better look in the morning

Try a few PD tests at the point of test, maybe there's a voltage present that shouldn't be.
