Megger MFT1721 FUS fault code

[Michaelp]

Today i had the megger dropped from a meter height and is now showing the FUS code.

Checked the fuses, Both are good. Contacts look very good. New batteries installed but still get the same code. I did the reset just in case but no results.

This Megger is not in the warranty, is quite old and used. So now i tried to open it just to check if there is any wire, fuse or something visible lose caused by the drop.

My issue how do you open it ? Looks quite cumbersome and difficult. Anyone tried to open it ? I search to find somebody who did that but cant seem anyone open one yet ?

Tel will be along shortly no doubt with a method involving a hammer ?

screws in case visible top and bottom. other screws behing front panel stick-on. peel off carefully to reveal screws. then you can split the case.

Ok opened it. Looks like its a part came of from the pcb...weird because was solder on pcb...
@Tel there are no screws under the sticker.I remove only the bottom 6 screws and pull out the lead contact panel and came out like a candy bar

A surface mount mechanical relay. Looks like you may have been lucky and it may not have ripped the pads/tracks off the PCB.

Resolder it, carefully, and check for any other damage. Looks like it went with quite an impact!

Nice one! Get it calibrated to make sure everything is still working correctly. And have a beer to celebrate!
