I'm brand new to electronics and trying to teach myself using the "make: electronics" book.
I bought the $45 multimeter Radio Shack along with the components for the first few experiments but I'm having a problem measuring current.
Supposedly the main raid can measure current, you're just supposed to switch to the other outlet for large currents. I can measure voltage and ohms fine but I can't get the mA to work. I'm using a circuit with 4AA batteries, a resistor and a LED. When i switch to the other outlet it works but it only shows A not mA so I only get one significant digit. I tried switching fuses but I get the same thing.
Am I doing something incredibly dumb which has cost me two fuses or something incredibly dumb and just not getting it to work?
Thanks in advance for any help,
Matt
