Description of Figure 11.
Custom min and Custom max parameters configure the input range for analog input that will
affect Frequency reference.
Blue line shows an example with Custom Min = -100% and Custom Max = 100%. This settings
provides a frequency range between (Maximum frequency - Minimum frequency)/2 and Maxi-
mum frequency. With minimum analogue signal the Frequency reference is at 50% of the set
frequency range (Max frequency - Min frequency)/2. With maximum analogue signal the Fre-
quency reference is at Maximum frequency.
Green line shows the default settings of custom values: Custom Min =0% and Custom Max =
100%. This settings provides a frequency range between Minimum and Maximum frequency.
With minimum analogue signal the Frequency reference is at Minimum frequency while with
the maximum level is at Maximum frequency.
Orange line shows an example with Custom min = 50% and Custom Max = 100%. These settings
provides a frequency range between Minimum and Maximum frequency. The Frequency refer-
ence changes linearly within the frequency range with the analogue signal between 50% and
100% of its range.
