I received the replacement fuses today...pretty quick delivery, and just as advertised.

 

The DMM-11A fuse in my Fluke 115 seems to be open. How could I have done that? I don't want to do it again.

I think I would replace my KTK-20 with one of those, as getting a replacement and spare for my Fluke-27 @$39 ea would cover the cost of new meter.

 

All I can say is, Post #2. We've all done this. I just makes me crazy to pay $10 for a fuse. They couldn't possibly be that expensive to build.
