Introduction
This is a step-by-step guide to replace the fuses of a Velleman DVM020 multimeter.
This multimeter includes two fuses with the following specifications:
- 10 A - 600 V: protects the high current measurement function
- 200 mA - 600 V: protects most of the multimeter's functions
If your multimeter stops measuring current in the 10 A mode, the 10 A fuse likely needs to be replaced with the following:
- 5 x 20 mm 10 A - 600 V ceramic fuse
If your multimeter stops measuring voltage, resistance, or current, the 200 mA fuse is likely blown. It must be replaced with the following fuse:
- 5 x 20 mm 200 mA - 600 V ceramic fuse
Do not install fuses with higher amperage or voltage ratings than the specifications, as this could damage your multimeter. You can safely install fuses with lower current or voltage ratings; your multimeter will simply not function at full capacity.
Fuses rarely need to be replaced, and blown fuses are almost always the result of human error.
