PM3: Can I enter weight?

[bdsman]

I have the PM3 w/firmware version 107. Am I able to input my weight? Doesn't a heavier person use more watts (at the same effort)? My understanding is that without the correct weight, the ergomerter can't give me an accurate calculation of my watts (and therefore calorie expenditure).

No you cannot enter your weight, you don't need to worry about it.

The Watts is derived from the power put into the flywheel.

Your either a heavyweight or a lightweight as far as comparisons of your performance is concerned and thats about it.

Correct - and the Calories, as shown on the monitor, include that but also throw in an extra 300 Calories to account for an estimate of the additional work done that is not measured by the monitor. The 300 figure is based on an arbitrary standard - something like a 180# man in good condition. It can be adjusted to specific individuals, but I don't have a link to that information handy. The additional work is what is done to accelerate and decelerate the body back and forth in the slide. On a bike, in answer to another post on a different thread, there is not as much additional work needed, so results from bicycle monitors usually show a higher power output than that of an erg for an individual.
