Testing replacement fuses for Fluke multimeter from AliExpress
I just wanted to double-check the voltage before plugging the power supply connector into my board and then I was confused because it read as zero volts. Of course, I had still plugged the test leads into the current input and of course that killed the fuse. My other multimeter (an older Mastech) complains very loudly when the leads are plugged into the wrong holes but this time I was using the Fluke. Fuses can’t be too expensive, can they? Well, they can . That’s more than 10€ with shipping and other sources aren’t much cheaper. On Ebay, I saw cheap alternatives with shipping from China and I was curious. I ordered 10 pieces on AliExpress for 15€, which is only slightly more than what I would have paid for one original. I had some previous experience with polyfuses from AliExpress: They were rated for 2A/6V but they work “very well” for 15A (until I stopped the test because the test leads were getting hot - I hadn’t planned to test with such high currents). Thus, the Ali fuses will certainly not go into my multimeter without a thorough test! Original fuses are labelled with “Bu
