(4202)
!
Note!
This function is not available unless the FREQUENCY setting was selected in the
OPERATION MODE function (4200).
Use this function to define 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 77.
User input:
5-digit fixed-point number: 0...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.

FREQUENCY
(4203)
!
Note!
This function is not available unless the FREQUENCY setting was selected in the
OPERATION MODE function (4200).
Use this function to define a full scale frequency for the frequency output. You define the
associated measured value of the measuring range in the VALUE F HIGH function (4205)
described on page 77.
User input:
5-digit fixed-point number 2...10000 Hz
Factory setting:
10000 Hz
Example:
• VALUE F HIGH = 10000 kg/h, full scale frequency = 10000 Hz:
i.e. a frequency of 10000 Hz is output at a flow of 10000 kg/h.
• VALUE F HIGH = 3600 kg/h, full scale frequency = 10000 Hz:
i.e. a frequency of 10000 Hz is output at a flow of 3600 kg/h.
!
Note!
In the FREQUENCY operating mode the output signal is symmetrical
(on/off ratio = 1:1). At low frequencies the pulse duration is limited to a
maximum of 2 seconds, i.e. the on/off ratio is no longer symmetrical.
