Frequency AC
for small AC frequency signals
[Hz], from wind sensors like R.M.Young Wind
Monitor
Counter
if you want to count pulses, e.g., from a
tipping bucket rain gauge.
Select the
Slope
and
Offset
for the transfer func-
tion of the respective input. Take these values from
the sensor data sheet or from the calibration certi-
ficate for individually calibrated sensors.
Select the option from the
Option
list:
---
if no option required.
no offset when zero
suppresses the offset for
0 Hz frequency signals. Select this option for
anemometers because otherwise wind speed
will record the anemometer offset value at
zero wind speed.
Example:
vWind80m (m/s) = 0.04727 * b10 + 0.264 * (b10>0)
The first part of the function name can be used as
variable
vWind80m in further measurement func-
tions.
The diagram title for this function is vWind80m , the y
axis label is (m/s) .
Digital Measurement Inputs (DIN1..10)
The table
Digital Inputs
provides one line for each
of the 10 digital measurement inputs DIN1..10.
Enter the function name into the field
Name
.
Select the signal type from the
Type
list:
---
if the input is not used.
Frequency TTL
for TTL pulse frequency signals
[Hz], from anemometers like Thies First Class,
Vector A100, Heval ECONOMY or RISØ reed
switch anemometer with external pullup re-
sistor .
