[QUOTE="Spooney, post: 6414009, member: 584130"] it should read your pre outs just fine or at least close enough to set your gain. Its probably not extremely accurate with that 200 volt range but hey thats all you got and it will get you close enough. Also 200 mA is not 200 millionths of an amp. 200 mA is 200 thousandths of an amp or .2 amps . Your not really gonna be able to use this dmm for any kind of amperage measurement. Chances are even a remote turn on output from your headunit is going to exceed .2 amps and don't even think about trying to measure your alternator output with this thing. [/QUOTE]
