Connecting sensors
Vibrating rope version
Refer to the figure contained on page 11 to connect the vibrating rope sensors.
The figure represents the datalogger’s multiplexer board.
Before connecting the sensors to the datalogger, it is a good idea to previously
check that they are working and properly wired upstream. For this it would be
useful to have a handy hand reader with you to check the transducers before
final wiring.
Connect the first vibrating cord sensor into the white-colored quadruple
terminal indicated by CH0. The first (from the top) screw terminal should be
connected to the positive pole of the sensor coil (COIL+) normally indicated with
the color RED. The second terminal should be connected to the negative (COIL -)
pole of the coil normally indicated with the color BLACK.
The OG3200PRO datalogger is capable of reading sensors with resonance
frequency above 501 Hz. The universal sweep requires no software setting, and
the data output is directly in Hz or Hz squared. For use with self-oscillating or
different frequency sensors, consult OTR directly.
Terminals 3 and 4 should be connected to the thermistor associated with the
sensor (normally color 3 to GREEN and 4 to WHITE).
The standard of thermistors read by the OG3200PRO datalogger is NTC 3Kohm.
If the thermistor is not of this type wire it and then proceed with the software
to read and record in Ohms. From these derive the data in degrees using the
corresponding formulas for the NTC or PTC sensors used.
Repeat the operation with the next sensors, taking care to connect the quad
clamps sequentially one after the other (if an empty quad terminal is left
between two wired with sensors it too will be unnecessarily read and recorded).
Check that the screw terminals are tight and that the wires are not shorted.
After all sensors are wired, proceed with a continuous measurement to check
that the whole operation was successful.
DATALOGGER D3200PRO
mV or 4-20mA version
To connect sensors with mV or 4-20 mA output, refer to the figure contained on
page 24. The figure represents the datalogger’s multiplexer board.
Before connecting the sensors to the datalogger, it is a good idea to previously
check that they are working and properly wired upstream. For this it would be
useful to have a handy hand reader with you to check the transducers before
final wiring.
To connect sensors with mV output, locate the sensor power cable and connect
it to the first slot (from the top) of the quad terminal. Wire the sensor ground
(GND) wire to the second slot and finally the signal wire to the third slot. If the
sensor is biaxial (ex: inclinometer) connect its second output to the third slot of
the next quad terminal, taking care to return the power supply to the latter (so a
loop must be made between the first slot of the quad terminal ex: X and the first
slot of the next quad terminal ex: Y). In this way, the biaxial sensor is properly
connected and powered. Check that the black 4-20 mA selection jumper is
disconnected. The voltages read by the datalogger range from - 4,000 to +
4,000 Vdc. Higher or lower values will be reported as Full Scale and will not be
read correctly.
To connect sensors with two-wire 4-20 mA output, locate the power cable
(LOOP+) and the signal cable (LOOP-). Wire the LOOP+ cable to the first slot of
the quad terminal and the LOOP- cable to the third. Check that the black 4-20
mA selection jumper is connected.
For connecting sensors with 4-20 mA three-wire output, locate the power cable
(LOOP+), signal cable (LOOP-) and ground cable (GND). Wire the LOOP+ cable
to the first slot of the quad terminal, the GND cable to the second and finally
the LOOP- cable to the third. Check that the black 4-20 mA selection jumper is
connected.
Check that the screw terminals are tight and that the wires are not shorted.
After all the sensors have been wired, proceed with a continuous measurement
to check that the whole operation was successful.
For sensors with mV output, it is essential that the 100-ohm load resistor be
disconnected by removing the black jumper. Incorrect use of this jumper results
in unexpected low signal values
For sensors with mA output, it is essential that the 100 Ohm load resistor is
connected by inserting the corresponding black jumper. Incorrect use of this
jumper results in full-scale values. Correct use gives values of 0.400 volts
for 4 mA and 2,000 volts for 20 mA found between slot 2 and slot 3 of the
corresponding quad terminal.
The datalogger is capable in all cases of reading currents between - 40,000 and
+ 40,000 mA, and the instructions for 4-20 mA sensors also apply to 0-20 mA
sensors.

The screen allows access to the datalogger’s clock parameters and acquisition
enablement.
The Read Date and Write Date buttons allow the user to update the date entered
in the datalogger on the screen and to edit the date within it if necessary,
respectively. Editing is done by selecting the relevant data boxes and then
pressing the write button.
At the bottom is a check that indicates whether the datalogger is enabled for
conversion or not. If the check is selected the datalogger acquires at each
conversion time starting when the program is closed or the cable is disconnected.
If the check is not selected the datalogger is in stand-by and does not acquire. Its
consumption in this state is about 200 µA.
Data Mood
With these options you set the acquisition times of the datalogger. Times
below one minute cannot be set, and if channel scanning exceeds this time it is
automatically delayed. For the version with GSM the acquisition times cannot be
less than 10 minutes.
Also in the screen is the setting of pre-start times that control how long the
datalogger waits before taking a sensor reading. For the vibrating string version,
the preignition time is meaningless.
Timers
In this screen you can manage the quantity of channels connected to the
datalogger. The two buttons Read and Write are used to control these parameters.
For each MUX, 0 to 16 active channels can be set. When changing these values,
the software asks for confirmation because the memory is reset if the channel
configuration is changed. This is necessary for internal dislocation of data in
the datalogger. Therefore, before adding or removing channels remember to
download the data.
If the value of channels is set to 0 the corresponding MUX is ignored and the
memory possibility is increased as follows:
1 MUX 4000 data
2 MUX 2000 data
3 or 4 MUX 1000 data
The Clear Data Memory button allows the datalogger’s memory buffer to be
completely cleared.
The Reset Datalogger Completely button, on the other hand, allows the datalogger
to be returned to its first power-up state. However, this operation results in the
loss of all data and also all configurations and should only be used if strictly
necessary.
Channel Managing
mV/mA version
The properties of the various sensors are accessed with the appropriate button.
Each sensor is identified by a number ranging from 0 to 15 and its MUX number
ranging from 0 to 3.
For each sensor, a name and four numeric configuration parameters can be set,
allowing for a given output in any physical format.
The reference formula is as follows:

Actually, the formula is very simple and does not require any special calculations.
It is sufficient to take two points on the characteristic curve of the sensor and
proceed as follows:

The transducer has an output of 4 mA at 0 mm and 20 mA at 100 mm therefore:
At 4 mA the Zero value in tenths of millivolts corresponds to 4000 and at 20 mA
the Full scale value in tenths of millivolts corresponds to 20000.
The four values are then:
Zero_Volts = 4000
Fs_Volts = 20000
Zero_Physical = 0
Fs_Physical = 100
The output is thus in mm. If you want to have it in cm simply put
Fs_Physical = 10
4-20 mA potentiometric
transducer -100 mm
Inclinometer with output +/- 2 volts
around 2.5 volts and FS=+/- 30°
The transducer has a nominal zero at 2.5 V corresponding to 25000 tenths of a
millivolt.
Zero_Volt = 25000
The value indicated by the transducer at this position is nominally 0°
Zero_Physical = 0
At full scale, the transducer has an output of 4.5 volts corresponding to 45000
tenths of a millivolt.
Fs_Volt=45000
At this position the inclination is equal to +30°
Fs_Physical = 30
Here are found the four parameters for having an output in degrees (of course the
software also leaves a reasonable number of floating-point digits).
Piezometric transducer
4-20mA 20m water
Il trasduttore ha un’uscita di 4 mA a 0 m e quindi di 20 mA a 20 m:
A 4 mA il valore di zero in decimi di millivolt corrisponde a 4000 e a 20 mA il valore
di fondo scala in decimi di millivolt corrisponde a 20000.
I quattro valori sono quindi:
Zero_Volts = 4000
Fs_Volts = 20000
Zero_Fisico = 0
Fs_Fisico = 20
L’uscita è quindi in m. Se si desidera averla in cm basta mettere
Fs_Fisico = 2000
Barometer with output in volts
The transducer in example has an output of 0.1V at 15KPa and 2.35V at 115KPa:
At 15Kpa the value in tenths of mV is therefore 1000 while at 115Kpa it is 23500.
The four values are therefore:
Zero_Volt = 1000
Fs_Volt = 23500
Zero_Physical = 15
Fs_Physical = 115
The output is thus in KPa.
Example of data file
The data downloaded from the datalogger are easy to interpret and collect all
information regarding the sensors and their properties.
If immediate visualization of the data is desired, simply select the ‘Create Table ‘
option before downloading.
An example file of the ASCII file created is shown.
The file shows the date of download the various sensor information and the data

Calculation of Battery Autonomy
Il consumo in stand by del datalogger è di circa 200 µA.
Il consumo in pieno utilizzo (durante la misura) si aggira intorno ai
100 mA.
Approssimatamente il tempo di acquisizione per canale può essere
considerato 4 sec a cui va sommato un tempo di 10 sec ad ogni
accensione.
Partendo da questi due dati è possibili con semplici calcoli calcolare
in modo ragionevole la durata prevista delle batterie.

The standby consumption of the data logger is about 200 µA.
The consumption in full use (during measurement) is around 100 mA.
Approximately the acquisition time per channel can be considered 4 sec to which
should be added a time of 10 sec at each power-up.
Starting from these two data, it is possible with simple calculations to reasonably
calculate the expected battery life.

Battery Datalogger phone module
If the datalogger supplied has the telephone module, a solar panel or battery
charger is also provided. The phone consumes approximately 30 mA and the
battery/panel system is sized according to the area and conditions of use.
If sizing is correct and external factors (snow on the panel, leaves etc. etc.) do not
intervene, however, the life of rechargeable batteries should be considered to be
about a couple of years due to aging factors and loss of storage capacity.
Where possible and reasonably safe, it is advisable to use solar panels and
rechargeable batteries that isolate the datalogger in every way from unwanted
external disturbances.
Replacing Flashlight Batteries
Use model LR20 SIZE D alkaline flashlight batteries. Be careful that the batteries
do not release acid.
Battery Replacement
Replacement of Batteries with
sealed lead-acid
Use 6Vdc 12Ah sealed lead acid batteries after proper and sufficient charging.
Software Conventions
Per il corretto utilizzo del software OG3200PRO devono essere controllate alcuni
parametri di Windows nel pannello di controllo.
Entrare in start e successivamente in opzioni internazionali e numeri.
Il simbolo di separazione decimale deve essere “ . ” ed il simbolo di raggruppamento
cifre “ ’ ”.
Se queste convenzioni non vengono rispettate il programma non riceve i dati dal
datalogger in modo corretto.
Serial connection and USB adapters
The OG3200PRO datalogger uses a standard 3-wire + 1-wire RS232 serial
connection for awakening from the standby state. It is therefore necessary to have
a full serial. The OG3200PRO version that is not GSM-ready has a 57600,n,8,1
protocol the GSM-ready version 9600,n,8,1.
Common USB/Serial adapters are perfect for connection with the OG3200PRO
datalogger. In case of using adapter, the supplied connection cable is not necessary
either. The connection can be made in a direct way.

• Check for the presence of moisture
• Check international settings and setting of sensor parameters
• Check the status of the batteries
• Remember that for biaxial sensors it is necessary to report + power on each
quad terminal used for them.
The measurements do not seem
correct
• Check that the PC in use has no other programs running.
Downloading data is difficult and
time-consuming
GSM and Solar Panel
To connect to the GSM modem, simply use the cable supplied with the phone and
plug it into the appropriate connector.
Remember that for local connection it is necessary to disconnect the GSM serial
socket in order not to have two devices on the same line.
The OG3200PRO with the GSM phone works at 9600 baud so for local connection
you must use the ‘GSM Version’ option in the initial screen of the software.
Upon connection the GSM modem will start flashing in the presence of the field.
Remember to use prepaid or non-prepaid cards enabled for incoming traffic.
It is necessary that the card inserted in the GSM is unlocked i.e. with PIN request
disabled.
GSM modem connection
Also supplied with the GSM version is a 10W solar panel, a 12/18 Vin, 7.2 Vout
panel charger, a 6V-12 A/h sealed lead-acid battery with very high range.
Do not use the battery charger with panels with power higher than 15W.
Do not use different panel chargers (standards are 12 Vdc Out).
Caution in full charge the charger radiator can reach up to 70°C.
Using the solar panel

• Use the charge module in the following way:
Connecting the solar panel and
panel charger
VDAT:
Positive datalogger power supply (red wire)
GND:
Negative datalogger power supply (black cable)
VPAN:
Positive panel voltage (color depends on panel supplied)
GND:
Negative panel voltage (color depends on panel supplied)
VBAT:
Positive battery voltage (red wire)
GND:
Negative battery voltage (black cable)
It is also possible to plug into the VPAN/GND input the output of a stabilized
12/18 Vdc 1 Amp power supply to put the battery on charge before installation or
to power the datalogger with mains voltage.
NB: In case of mains power supply, it is necessary to make sure that the power
supply is professional and adequate, protected from surges, with surge filters.
Otherwise sudden surges and disturbances from the mains could make it
impossible for the device to work properly.
It is also recommended not to carry out programming with the datalogger under
charge with a mains power supply and a PC also connected to the mains.
If the datalogger does not have sealed lead-acid batteries (flashlight battery
version without GSM), do not try to recharge the batteries.
Installation and Maintenance
The housing supplied with the datalogger has a protection rating of IP65 or IP66.
The housing must be properly closed and each of its cable glands sealed with
a piece of cable if not in use. If operating under special conditions (particularly
humid environments, freeze-thaw cycles), additional protection is recommended
to avoid condensation problems inside the housing.
Installing
Maintenance of the data logger is limited to a few simple rules:
- Check the condition of the battery at each data dump
- Check the internal condition of the box to prevent condensation moisture
problems.
If not in use for several months, the following rules should be followed to
safeguard the internal buffer battery:
- Recharge or replace the external batteries after the last measurement campaign.
- Store the datalogger with the external batteries connected in the stand-by
condition.
Under this condition, the life of the buffer battery is unlimited.
The life of the internal buffer battery is unlimited under normal use but becomes
6-12 months under complete non-use. Therefore, it is recommended to store the
datalogger in stand-by condition to avoid unnecessary discharge of the buffer
battery.

If you feel that you have not followed the previously described steps correctly
after a long period of inactivity of the datalogger, it is advisable to replace the
internal battery. The battery is lithium and readily available (PANASONIC model
CR2330 or equivalent).
The operation LED of the datalogger to indicate the complete reset of the
equipment flashes 4 times at the first power on.
This operation implies the loss of data and configuration of the datalogger.
After disassembling the plate that holds the datalogger you will easily find the
battery holder. Replace the buffer battery with an equivalent one taking care not
to short-circuit it in disassembly and reassembly. Take care to mount the battery
with the correct polarity indicated.
The operation described above should be done by disconnecting the main
batteries first.
When replacing the buffer battery with the external batteries connected, it is
necessary to press with a pencil the yellow metal button “RESET” located on the
rear board of the datalogger.
