2.7. Recording other inputs
The Data Logger converts the input signals of the sensors into predefined
measured variables. The impulses of an anemometer are converted for example
into m/s based on the entered calibration values. If you set the calibration factor
Slope = 0, thereby the internal conversion is switched off and the measurement
categories are indicated as master data. (Signal inputs in Hz with resolution of
0,1 Hz, Analog inputs in mV)

2.8. Ultrasonic anemometer
All Ammonit Data loggers can be used in combination with meteorological
ultrasound sensors from Gill Instruments for wind measurements. These high-
resolution, one to three dimensional sensors (WindSonic, WindObserver, or
WindMaster) are connected via the RS485 interface (2-wire cable) and activated
via their own channel in the "Channels“ window of the CALLaLOG02 software.
Sonic Hor.:
Horizontal wind speed in cm/s
Sonic Dir.:
Wind direction in degrees
Sonic Ver.:
Vertical wind speed in cm/s (nur Master)
Note that the vertical wind speed is stored with an offset of "1000". Three-digit
values indicate downward air flows.
Before connecting up the sensors these should be configured appropriately. The
necessary settings are shown in the connection plan. Further information about
the sensors can be found in the anemometer manuals.
