1. Installation
1.1. Overview
The Data Logger is a universal tool for the detailed registration of meteorological
data.
The different types of logger "series 32" differ only in the number of input
channels, i.e. the three connection sockets of the WICOM-32 are identical to
those of the METEO-32 and METEO-32X. So it is very comfortable to use larger
loggers in smaller measurement configurations, or alternatively to start using a
smaller logger in extended measurement systems.

1.2. Starting up
After you have unpacked the logger, you should first familiarise yourself with the
basic functions. To do this you must connect it to a power supply.
Either inset the batteries, or
connect to an external e.g. 12 V DC supply.
You will find detailed information about the energy supply in Chapter "Energy
supply".
The display then comes on and as the system starts it shows:

1.3. Display & button functions
The Data Logger has a 2-line display and three buttons on the left-hand side.
The buttons can be used to display various information and
to carry out test functions, making it easier to check the
system during installation and maintenance. On-site you
only need to check the system is operational and start
measurement simply by pushing a button. There is no need
to expose sensitive equipment (notebook, PDA) to the
weather.
In order to save power, the display only comes on when necessary.
Display on: Press any button
Display off: Press and hold the  button for about 2 seconds (Select)
The display switches off automatically 30 minutes after the last button was
pushed.

2. Sensors
The connections to the sockets of the individual logger types are 100%
compatible. The WICOM-32 can register three wind speeds and two wind
directions, whereas the METEO-32 also has additional sockets for humidity,
temperature, air pressure, global irradiation and precipitation and the METEO-
32X has additional inputs which are not pre-defined (ADC, Counter, Status).
Details of the wiring to the sockets is provided in the Annex.
2.1. Anemometer
To measure wind speed attach an anemometer with impulse output. The
characteristic of the anemometer is given in the form of a linear equation with a
gradient and an intercept at 0 m/s:
v = a ·I + b v = Wind speed
a = Gradient of characteristic
I = Pulse rate
b = Intercept of characteristic
The parameters are entered with the "CALLaLOG" software: the gradient is in
0.1mm/pulse rate and the intercept in cm/s.
The Data Logger counts the pulses of the anemometer signal and calculates the
wind speed (in m/s) to one decimal place. The individual measurement values
therefore represent exact means for each completed measurement interval.
The display shows the wind speed in [m/s]
S
Sy ys st te em m M Mo on ni it to or r * *
A
An ne em mo o1 1: : 5 5. .8 8 m m/ /s s
All wind speed values are stored in dm/s, so that they must be divided by 10
before being used (this can be done automatically by the "CALLaLOG" program
during data transfer).

Ammonit Data Logger Manual
16 Ammonit GmbH / 2005 - 2009
2.2. Wind vane
To register the wind direction attach a serial opto-electronic sensor or a wind
vane with a potentiometer, which should have a total resistance of 2000 Ω-
10 k Ω. The potentiometer is addressed ratiometrically, to make allowance for
temperature and cable influences on the measurements. Results are
independent of fluctuating supply voltages and the resistance of the
potentiometers. The resolution of a 2000Ω-vane is 1°with a precision of ±1°
over the entire temperature range. Calibration is not necessary, but may help to
correct for any offset of the wind vane introduced during the installation.
d = U + O d = Wind direction
U = Measured value
O = Offset (Angular deviation to North)
The measurement values are presented in 1°-steps from 1°... 360°, measured
clockwise:
V
Va an ne e1 1 : : 3 34 42 2° °
Any implausible measurement values are documented as "777".
The directional data is stored in 1 degree steps. Mean values are calculated,
and of course the mean of "1°" and "359°" is record ed as "North (360°)" and not
"180°"!
2.3. Hygro/Thermo
These inputs are only available for the "METEO" versions.
Either a simple temperature sensor (e.g. the "TPC", P6471) or a combined
hygro / temperature sensor (e.g. the "KPC", P6831) can be connected directly to
the "Hygro/Thermo" socket.
The temperature sensor contains a resistance thermometer, and the
measurement is converted by the sensor into a voltage proportional to the
temperature. For the correct evaluation of the measurement signal enter the
gradient and the intercept of the sensor characteristic as parameters.
T = a ·U - b T = Temperature
a = Gradient
U = Measured voltage
b = Intercept
The gradient is in °C/V. The temperature reading in °C for 0 V output voltage is
entered as the Intercept value.

Sensors
Ammonit GmbH / 2005 - 2009 17
The display shows the value in °C:
T
Te em mp p. .1 1: : 1 18 8. .4 4° °C C
Temperature data is stored in tenths of a Kelvin. [0°C = 273,15 Kelvin]
The humidity sensor consists of a capacitor sensor element with an integrated
converter circuit.
For the calculation enter the gradient in
Volt
humidityrel.%
.
F = a ·U F = Relative humidity
a = Gradient
U = Measured voltage
The display shows the relative humidity as a percentage:
H
Hy yg gr ro o : : 4 45 5 % %
The relative humidity values are stored in % .
2.4. Air pressure
These inputs are only available for the "METEO" versions.
A barometric sensor can be attached with an active analog output, such as the
Vaisala "PTB100A" or the "AB60" from Ammonit. The output signal is
proportional to the air pressure. You have to enter the start of the measurement
range [in hPa] and the gradient of the sensor characteristic in [hPa/V] as
parameters.
P = a ·U + b P = Air pressure
a = Gradient of characteristic
U = Measured voltage
b = Intercept of characteristic
The display shows the air pressure in hPa:
B
Ba ar ro o: : 1 10 01 17 7 h hP Pa a
The data is stored in hPa.

Ammonit Data Logger Manual
18 Ammonit GmbH / 2005 - 2009
2.5. Pyranometer
These inputs are only available for the "METEO" versions.
Pyranometer, e.g. from the "CM" series of Kipp & Zonen, will be connected via
pre-amplifier which aligned the µV signal to the data logger (0 - 1.2V). The
output signal is proportional to the global radiation.
For the calibration you must enter the gradient of the characteristic in
[ W/m²/V ] as parameters.
R = a ·U R = Global radiation
a = Gradient
U = Measured voltage
The display shows the global radiation in W / m²
P
Py yr ra an no o: : 9 92 26 6 W W/ /m m2 2
The global radiation values are stored in W / m².
2.6. Precipitation sensor
These inputs are only available for the "METEO" versions.
Registering precipitation requires an impulse input, for example from a "Rain
Gauge" from R.M.Young (P6720/1).
For the calibration you must enter the gradient of the characteristic in [µm /
impulse].
N = a ·I N = Amount of precipitation
a = Gradient of characteristic
I = No. of impulses registered
The display shows the precipitation during the last measurement interval
[0.1 mm]:
R
Ra ai in n: : 4 4. .8 8 m mm m
Data is stored in [0.1 mm/minute], so that before evaluation the numbers must
be divided by 10.

Sensors
Ammonit GmbH / 2005 - 2009 19
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)
Master data of measurement categories
Input Measurement range Resolution
Anemometer 1...3 0 ... 1000 Hz 0.1 Hz
Rel. humidity 0 ... 1200 mV 0.1mV
Air temperature 0 ... 1200 mV 0.1mV
Air pressure 0 ... 5000 mV 0.5 mV
Rain 0 ... 1000 Hz 0.1 Hz
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.
