[QUOTE="shizzzon, post: 8459378, member: 590338"] If you are wanting to measure output of something, you can use a multimeter AND an ammeter. Although, this method will only tell you the VA (volt amps). Because AC is alternating, voltage and current usually are never in sync so the VA number will read higher than the true watts. To get True watts, the device must take into account things like Phase Angle and Power Factor. Devices which do this are- SPL-Lab Next-Lab USB + AC Clamp SPL-Lab Next-Lab LCD + AC Clamp SMD AMM-1 Those are the common devices in the audio world. However, depending on how much you want to learn depends on how much you are willing to pay for such devices. Purchasing a True RMS ammeter along with your multimeter can get you VA which is decent enough for troubleshooting issues. VA when measuring several thousand VA can be over 1,000w off accuracy easy. The devices listed above are typically between $400-550. So, it really all depends on your motivation. [/QUOTE]
