Fig. 6.6−3 Setting of the operating range for the KTY (C1190 = 1)
The operating range is specified by means of limit values and is in the almost
linear section of the graph (a). The operating values are determined by
interpolation.
C1191/1
C1191/2
Setting of the lower and upper temperature value (T1, T2)
corresponding to the KTY used.
C1192/1
C1192/2
Setting of the lower and upper resistance value corresponding to
the KTY used.
