Popped EXPENSIVE Bussmann 44/100A 1000V fuse in BM869 DMM

I was in mA mode, and connected a 555 timer pin3 to gnd, so I popped the expensive fuse. Also that night, I hooked a 45 Ohm speaker between 555 output pin3 and pin4 ground,I wanted to hear the measured frequency, but the 555 heated way up and even melted some of the bread board


I want to connect 200mA fuse in place of Bussmann 0.44mA fast acting fuse, big, ceramic, 10mmx39mm(or 34.5?mm)

Now, I should set up transistor 200mA current, and time these fuses, but I only have a few of them too

There's nothing I'm doing that needs over 200mA, so if I put descent 200mA fuses in this BM269, I should be good

I have accidentally zapped my Vici VC99 too many times, her mind is going.....so for now she is relegated to mA current measurements.

Wow 44/100mA and more info fuses are EXPENSIVE mistakes

You blew the HRC 440mA fuse. Just replace with same and be more careful next time. Always select 10A range first. Only use the mA range if you need the extra resolution and you made sure the current draw is well within the mA range limitation.

Using a power supply with current limiting avoids such problems.
