According to the manufacturer the Kaiser M3 is not calibrated and they make no claims about the accuracy of their power estimates. The best you could hope for is that it remained consistent over time. It shouldn't stop you from getting a good workout though.

I agree with NoRacer that power meters don't need to know your weight.
