You can configure output scaling or transfer function settings in many
ways by changing the custom gain and offset. The basic measurement
units are m/s and degrees. The physical output unit is A. The following
formula shows the impact of gain and offset values on the produced
output:
o = y0 + k×s
Analog Output Signal for Wind
Speed Channel
The analog interfaces setup, default configuration:
Current output 4 ... 20 mA, offset 4 mA
4 mA = 0 m/s
20 mA = 60 m/s (0,266667 mA/m/s)
Error indication sets output to 2 mA.
The analog interfaces setup, configuration 2:
Current output 0 ... 20 mA, offset 0 mA
0 mA = 0 m/s
20 mA = 60 m/s (0.333333 mA/m/s)
Error indication sets output to 22 mA.
where
o = Produced analog output (A)
s = Measured wind speed or direction (in m/s or °)
k = Selected gain value
y0 = Selected offset value
