For some reason whenever I play with a multimeter it always gives me results I never expect. In this case I am attempting to measure the current of a AA battery. I have the multimeter set to 10A on the dial and connecting red to the negative end of the battery and black to the positive end, giving me a reading of about +6.8. However if I switch the dial to 200mA with the same connections the reading goes off the scale but with a negative number, -1. Is this behavior normal? It is a digital Southwire 10030S multimeter.
After testing with an analog meter putting negative to negative and vise versa I get a positive reading of about 5 amps though the gauge gets stuck usually. It says PRIME Cleveland Ohio on the back.
Looks like I had the fuses in the back swapped with each other and after correcting it is now matching the readings of the analog meter :D
