3203
Float
read/write
! Note!
Function is not available unless the FREQUENCY setting was selected in the
OPERATION MODE function (4200).
For defining an initial frequency for the frequency output. You define the
associated measured value of the measuring range in the VALUE F LOW function
(4204) described on Page 70.
User input: 5-digit fixed-point number: 0 to 10000 Hz
Factory setting: 0 Hz
Example:
• VALUE F LOW = 0 kg/h, initial frequency = 0 Hz:
i.e. a frequency of 0 Hz is output at a flow of 0 kg/h.
• VALUE F LOW = 1 kg/h, initial frequency = 10 Hz:
i.e. a frequency of 10 Hz is output at a flow of 1 kg/h.
