Sets the gradient level and off-set value of the output frequency in relation
to the input voltage. These codes are displayed only when IN-06 is set to ‗1
(bipolar)‘.
As an example, if the minimum input voltage (at V1) is set to -2 (V) with
10% output ratio, and the maximum voltage is set to -8 (V) with 80% output
ratio respectively, the output frequency will vary within the range of 6–48
Hz.
