Why is the current value 0,0 when the mAVΩ port is used?

I am learning electronics as a hobby. Today, I was using the multimeter to learn current, voltage and resistance in a simple circuit.

I setup the breadboard with these parts:

• 470 Ω, 1⁄4 W resistor
• Red LED, 5 mm
• 9 V battery snap connector
• 9 V battery
• Short length of jumper wire (1" or less)

I can read voltage in the circuit perfect but with current the readings on the multimeter is 0.0 when using the 10A port (LED turn ON) and with the mAVΩ port (LED doesn't light up) to replace the jumper wire. Did I burn out the fuse on the device?

Update: I checked the connections and settings on the multimeter and still 0,00.

• reverse the probes, just to be sure Commented Nov 20, 2022 at 0:22
• Does the multimeter have a blown fuse? Commented Nov 20, 2022 at 0:31
• @jsotola I don't see what difference that would make, it should work either way, except that one way will show a negative current. Commented Nov 20, 2022 at 0:32
• After thinking for a while and getting a little headache I found out that the fuse was blown since the thin wire is snapped. Commented Nov 20, 2022 at 0:48

I doubt that it's the shunt, even a 100 $$\\Omega\$$ shunt should allow the LED to light. You can try using the 200 mA range, that might have a lower resistance than the 20 mA range. If you're not seeing the LED light up even dimly then the odds are the fuse is blown.
