Ampzilla with decade meters-4 orders of magnitude. VERY useful for training oneself, lower decade readings quite sensitive. I am a scientist, these things fascinate me.
What is the name of the tool?
Forgive my absence of knowledge, but what is the name of the tool that one uses to measure the wattage coming out of ones speakers. I called it a watt meter to my family and got something that measures the watts and current coming from the outlet to the powered device I was using instead, for Christmas.
