Fluke 725 repair

[kingsolmn]

Greetings StarFighters.

I've been tasked with repairing a Fluke 725 that appears to have been grabbed by a sparky and used on a mains voltage line. Anyway, the input protection seems to have done its job but I'm having trouble finding what the "proper" replacement fuse is supposed to be. I have attached pics of the full back of the mainboard, a close-up of the blown part (quite a spectacular failure, the pics don't do it justice!), and the board details. Btw, the board is a Martel (of course) Rev D board.

It would be really awesome if someone in the know can enlighten me with the correct fuse type/rating that's supposed to be there (4 places), or even a way to convert this board so that it has user servicable fuses like the manuals show. Considering the difference between what's on my bench and what has been shown by @somlioy's teardown photos, and @PA4TIM dealings in trying to find/produce schematics leave me with little hope of finding an official source of documentation.

Thanks in advance for reading and maybe having something to contribute! 

Also, do you all want to see better pics of the failure?

So, I've accepted that I'm not going to find an "official" designation of the fuse used. With that said, how would I go about determining an acceptable replacement for the failed fuse? The front of the case has the max ratings of 30V and 24mA but it doesn't give much in the way of other ratings I find in the parametric search. Does it even matter significantly about the other attributes of the replacement parts?

Which metrics are the most important and which ones aren't that important when selecting a replacement component in this case?

Thanks in advance!
