Steps to establish an instruments validity

A high tech computer company asks me to validate a wrist mounted device to measure exercise energy expenditure. So the individual exhales one breath into the top of the instrument while exercising. The device's electronic components and microproccor analyze expired air to compute oxygen consumption and energy expenditure. How would I go about creating an outline of steps necessary to establish the instrument's validity?

What is necessary to establish a causal relationship? Briefly explain how I would set up a research study to determine that a reduction in lean body mass is causing a decrease in max VO2. (I am assuming that part of it could be that if there is a decrease in lean body mass there is less oxygen required)
