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 for-
mula in this chapter are presented in advance; other equations and definitions of pa-
rameters are found in the
chapter 4.3.3. Coordinates in context.
