Atomic 5000.1 Clamp Testing

Meh, I don't think there is a sticky or anything. You need a true rms clamp meter and a dmm. Hook the DMM up to the pos and neg leads coming from the amp and set it up to measure AC voltage. Clamp the true rms meter around the pos lead coming from the amp and set it to measure AC current. Multiply the two numbers together to get power. Divide voltage by current to get impedance.

nicely put

just need to have a 30 sec 50 or 60hz tone to play well clamping the longer the better if ur doing urself. unless ur clamp and DMM have a peak read hold that helps out alot

it does have the ac amps option is this the same as ac current?

Yes current is the same as amps.Just clamp it around the POS speake wire and set it to the ACA setting.

thanks for the info man

Ya, the 50 or 60 hz thing is also a critical note. Cheap meters are calibrated to 60 hz usually. They figure you'll be measuring ac from the wall so it is calibrated to 60 hz.

Depending on how it is designed, it may measure lower or higher than what it really is.

Good meters like my Fluke 179 do much better at frequencies other than 60 hz sine waves. They also measure square waves and waves that arent a true sine wave MUCH more accurately into an RMS figure.

Not saying your results arent accurate, but the tests are only as good as the test equipment.

Either way, the numbers are impressive
