Don't i need one with 12V?Or do i have to do some math to figure out the correct values?
The most important lesson for beginners to understand about using digital multi-meters is the danger of attempting to measure a voltage if the meter leads/function are setup in current measurement mode. A current must be measured with the meter leads in series while a voltage is measured in parallel. A meter in current mode is in effect a direct short circuit (at least up to it's 10amp protection fuse, if it has a fuse) between the measurement leads and if you have a brain fart and attempt to measure a voltage it can cause damage to the circuit you are trying to measure. Some meters have a warning beeper if function is voltage but leads are in current mode.Lefty
