Electronic – How to interpret an ammeter

I would like to interpret my ammeter. I don't understand what the point with the numbers 2,20,200 means and what is the exact current I am measuring. Thanks

You've carefully trimmed the photos so we can't see where your probes are connected.

When using the 2m, 20m, and 200m ranges (switch positions) the red meter lead should be in the "Volts/Ohms/mA" socket, and the black lead in the "Com" socket. For the 20A range, the red lead should be in the "20A" socket.

I suspect you are using the "20A" socket for all readings. If so, the readings on the mA ranges will be meaningless.

If so, the correct current is read with the range switch in the "20 A" position, and the current is 0.05 Amp, or 50 mA.
