A lot of DMM don't come with HRC fuses. I always replace those with
HRC before letting the unwashed use them. Nonetheless, it still
happens with depressing regularity. I also use a cheap $1.50 6A fuse
instead of the $60 13A fluke DMM fuse. The cheap will never blow
later than the expensive one for an overload, but of course, is not
rated for 13A continuous. As none of the training program requires
more than 6A continuous, it is OK.
I did a test program before doing that, and it was quite interesting.
At 4.5 A constant, the Fluke blows after a while, even though it is
rated at 13A constant, whilst the 6A is happy, and always blows sooner
than the fluke fuse with a genuine overload.

Have you tried RS Components for HRC Fuses. My fluke takes them and they are
$28 for a pack of 5 last time I bought one. The downside for me is that they
only sell them in packs of five, for you that is a bonus ;o)
