When I was checking present with my Kaiweets KM 601 multimeter recently, I need to’ve pushed it also far and blown its internal fuse. So I chose to crack it open and check.

Opening the Multimeter

Initially, I saw to it the multimeter was off and unplugged from any circuit. The Kaiweets KM 601 has a back panel held together with a couple of little screws, so I ordered a precision screwdriver and thoroughly removed them. As soon as the back was off, I can see both integrates inside: a smaller sized 600 mA fuse and a 10 A one. Just gently pop them out, you would not intend to harm anything.

Examination The Fuses

With the integrates out, I reconstructed multimeter and utilized it to check the fuse. I determined to utilize the continuity setting as it’s the easiest means to inspect if a fuse is great or blown. I switched to the continuity setting (the one with the little audio speaker icon that beeps), plugged in the probes (black to COM, red to the V/ Ω port), and prepared yourself to test.

I started with the 600 mA fuse. I touched the probes per end of the fuse, making sure I had solid call with the steel caps. The multimeter beeped as soon as possible, a stable tone telling me the fuse was intact– current could stream with it just fine. That made sense due to the fact that I would certainly been testing greater currents when the Kaiweets KM 601 provided, so this tiny fuse wasn’t the one that took the hit.

Successive was the 10 A fuse. I touched the probes to its ends. No beep. I double-checked my probe placement and attempted once more– still silence. That verified the 10 A fuse was blown.

Double-Checking with Resistance

Just to be detailed, I changed my multimeter to the resistance setting (Ω) and checked both fuses once again. For the 600 mA fuse, the display screen hovered around 0. 2 ohms– which is what you would certainly expect from a great fuse. For the 10 A fuse, though, it just showed “OL” (open line), indicating boundless resistance. That verified the 10 A fuse was damaged and requires to be replaced.

I’ll need to find one with the very same dimension and exact same rating (10 A, 250 V) and pop it back in. With any luck, this helps if you ever before discover on your own in the very same place!
