Figure. 5.3.13 - 115. Ambient temperature coefficient calculation (linear approximation, three points).
This ambient temperature coefficient relates to a nominal reference temperature. The default is +40 °C
(the standard ambient temperature rating for machines) which gives the coefficient value of 1.00 for
the thermal replica. The settable thermal capacity curve uses linear interpolation for ambient
temperature correction with a maximum of ten (10) pairs of temperature–correction factor pairs. The
temperature and coefficient pairs are set to the TM> function's settable correction curve.
