About the Fuse question again:
Try to check out on the Agilent site or write your service center. I got my spare fuses there and they were much cheaper than in the online shops.
The 11A Siba fuse was 7,54€ incl. VAT. A fluke 11A fuse is around 8,5€ incl. shipping.
So it may be worth checking. You can check the prices only on the Agilent site if you go to the U1252B meter, on the right side you can click on a "spare parts" and see the fuses there. The prices there are excl. VAT and may change (mine were a bit cheaper).
Well, they do have a minimum order of 35Euro here, so I bought a bunch of them and paid no shipping.
...just in case if you need spare fuses
