4.3. Equations in the TME400

The TME400 enables calculation of different values from the measured data and in
the data entered in the TME400. For a better understanding, some variables and
formula in this chapter are presented in advance; other equations and definitions of
parameters are found in the chapter 4.3.3. Coordinates in context.
