INDIVIDUAL TEMPERATURE CORRECTION (ITC) FOR …
With increased temperature the dielectric response is quicker, which results in similar behaviour at higher frequency for AC excitation, or shorter time for DC excitation. In other words, the values change, but the general shape of the curves is preserved.
