4 Introduction
The OTT ecoLog 800 (3G) groundwater datalogger is designed to precisely measure and store groundwater levels and temperatures, as well as the specific electrical conductivity of the groundwater and to transmit these measured values through
a GSM cellular network. The OTT ecoLog 800 (3G) also calculates the salinity and
a TDS value (Total Dissolved Solids) based on the specific conductivity.
The pressure probe equipped with a relative pressure probe cell uses the hydrostatic
pressure of the water column to determine the water level. As a reference, a pressure compensation capillary in the pressure probe cable provides the measuring
cell with the current ambient air pressure. Erroneous measurement results due to
atmospheric air pressure fluctuations are thus eliminated. The OTT ecoLog 800 (3G)
measures the specific electrical conductivity using a 4-electrode conductivity sensor
with inte grated temperature sensor. The measurement electrodes are made of
g
raphite.
The temperature compensation process for the conductivity measurement and the
reference temperature used can be chosen as well as the calculation method for
the salinity.
The OTT ecoLog 800 (3G) is available in five measuring ranges:
0 … 4 m water column (0 ... 0.4 bar)
0 … 10 m water column (0 ... 1 bar)
0 … 20 m water column (0 ... 2 bar)
0 … 40 m water column (0 ... 4 bar)
0 … 100 m water column (0 ... 10 bar)
Based on a reference value that is input during startup, the OTT ecoLog 800 (3G)
default setting provides measurement results in the form of depth values. Alternatively, levels or pressure values are possible. The measurement intervals (sample
intervals) can be preselected as necessary.
The operating parameters are set using the "OTT Water Logger Operating Program" PC software. This software allows the system to be conveniently and flexibly
tailored to a wide range of measurement requirements of a station. The software
can be set to provide a basic or an advanced user interface. The basic user interface allows all settings to be adjusted within a single program window. In the
advanced user interface, the sample interval can be controlled e.g. by means of
limit events. The software also supports the execution of pumping tests.
The stored measured values are made available through an infrared interface
(IrDA) for wireless readout using PC on which the OTT Water Logger Operating
Program is executed.
The OTT ecoLog 800 (3G) includes a built-in cellular modem (with SMA antenna
connector) that is used for remote data transfer and remote parameterizing
1)
via
the cellular network. The remote data transfer can be optionally carried out by
SMS text messages or transmission services GSM, GPRS, UMTS
2)
or HSPA+2).
If necessary – e.g. when the signal strength of the cellular network is low at the
installation site – the factory installed radio antenna may be replaced by an external one.
The OTT ecoLog 800 (3G) is installed by simply hanging it into observation wells
of 2" in diameter and above. For this purpose, various adapters/suspension
brackets are available as accessories. For power supply, three options are available: lithium battery, DD type, 26 Ah capacity; lithium battery, D type, 13 Ah
capacity; or commercial alkaline batteries (only OTT ecoLog 800 with dedicated
battery holder). When using the DD type lithium battery, battery lifetime is
(depending on additional parameters) at least 10 years, taking into account one
single remote data transfer per day. The communication unit of the OTT ecoLog
800 (3G) can withstand temporary flooding (for details, refer to Chapter 23,
"Technical data").

7 If required: Connecting an external radio antenna
If the local signal strength of the cellular network prevents transmitting from the
closed observation well, an external radio antenna (accessory) is to be connected
to the OTT ecoLog 800 (3G). In this case, only the dedicated external radio
antenna specified by OTT must be used for this particular application (cable
length max. 3 m).
You may fasten the external radio antenna to a suitable location using the shim
and nut supplied (drilling a hole for the thread of the external antenna is required:
Ø approx. 18 mm). For this installation, an individual solution to fasten the external antenna must be found depending on the station.
If the observation well is closed by a top cap you need to have a hole in the
observation well so that the antenna cable can be routed to the outside (to prevent
rain water from entering into the observation well, it is recommended to place the
hole on the side). If required seal the cable feedthrough.
How to connect an external radio antenna
Depending on the particular local situation (diameter of the observation well, type
of the top cap, and other mounting characteristics), the external radio antenna
must be connected prior to or during installation. Please note the relevant chapters
8.2 through 8.4.
Carefully unscrew the factory mounted antenna by hand.
Route the plug of the antenna cable through a hole in the observation well.
Connect the plug to the antenna socket and hand-tighten the locknut.
Fasten the external radio antenna to a suitable location outside the observation
well.
Notes
When installing an external radio antenna, the minimum distance to people
and other electrical equipment or antennae must be at least 20 cm.
Additional accessories for optimizing the radio conditions at the station are
available on request (e.g. plastic top caps, top caps with external or internal
radio antenna).

gram saves the configuration in a "*.TXT" file.
Note
The file name of the "*.TXT" file is arbitrary. The operating program suggests a
combination of station number and station name.
How to export a configuration (OTT Hydras 3)
This export type is required to transfer an OTT ecoLog 800 (3G) configuration to
the OTT Hydras 3 user software. This "*.XML" file is read in via the Hydras 3
function "File", "Import Station Configuration (XML)".
From the "File" menu, select the "Export Hydras 3 (XML)" function.
In the "OTT ecoLog 800 (3G) – XML configuration" window, check the file
name, select the storage location, and click "Store" ➝ The operating program
saves the configuration in a "*.XML" file.
Note
The file name of the "*.XML" file is arbitrary. To avoid affecting later data
transfer, it should not be changed. The operating program proposes a combination of station number and station name along with the ending "*.STATION.XML".
How to import a configuration
From the "File" menu, select the "Import configuration" function.
For an already opened configuration, confirm "Ignore changes?" message by
clicking "Yes" (if necessary, save configuration in advance).
In the "OTT ecoLog 800 (3G) configuration import" window, select the appro-
priate "*.BIN" file and click "Open" ➝ The operating program reads in the
configuration from the *.BIN" file. (Prior to this, save any configuration that is
already open).
Note
The factory default configuration is found on the "OTT Water Logger Software"
CD-ROM.
33
For determining and displaying instantaneous values, the operating program
i
ncludes a so-called "Observer". The Observer also allows a manually determined
measured value, e. g. contact gauge value, to be entered into the datalogger
(Observer registration).
Various options can be set concerning the observer:
Options in the start window of the operating program:
– Directly and exclusively opening the Observer, or
– Opening of a window to set the operating parameters
Effect of an optionally entered Observer registration (pressure sensor):
– The Observer registration is only used as a check value or
– the Observer registration leads to a value change (set offset)
Suppress the display of the instantaneous value (pressure sensor) prior to enter-
ing an observer registration.
As an alternative to the following procedure, you may use a cellular phone to
show instantaneous values by SMS messages or to make observer entries. This
requires the "SMS info" feature to be enabled and set up. For more information,
please refer to online help in the operating program.
How to set the Observer options
Start the operating program.
From the "File " menu, select the "Options" function. (If the option dialog can-
not be called, a password must first be entered. Refer to Chapter 12.)
Enable the checkbox(es) of the required Observer option(s):
– Only observer mode
– Do not calculate manual input value with scaling
(only check value/no value change);

settings set.
17 Updating the OTT ecoLog 800 (3G) firmware
If required, you have the option of updating the OTT ecoLog 800 (3G) firmware
(operating system software). This makes sense, if e.g. devices delivered at different
times are to receive the same operating system version. Updating is carried out
via the operating program. According to availability, an updated version of the
OTT ecoLog 800 (3G) firmware can be found on the internet site "www.ott.com"
in the "myOTT" area.
How to update the firmware
Download the new version of the firmware (File: e.g. "5544730293_02001 -
_el800NG.bin" or "5544930293_01000_el800NG.bin") from the internet site.
Move the file "5544730293_XXXXX_el800NG.bin" or "5544930293_XXXXX -
_el800NG.bin" to the directory, in which the operating program is located.
Establish the PC/OTT ecoLog 800 (3G) communication link, refer to
Chapters 9.2 or 9.3.
From the "OTT ecoLog 800 (3G)" menu, select the "Firmware update" function.
Confirm message by clicking "Yes" ➝ The operating program copies the new
firmware to the OTT ecoLog 800 (3G). The OTT ecoLog 800 (3G) then determines and stores the water level, the water temperature and the specific conductivity again using the sample interval settings set.
Please note: During updating process, avoid breaking the communication
link (e.g. by accidentally removing the OTT DuoLink from the infrared interface
of the OTT ecoLog 800 (3G)). If the communication link is aborted, the
firmware will no longer be executable! Similarly, no other programs should be
started or files opened during the copying process!
Notes
If there are multiple ".bin" files in the directory you will have to select the
required file manually.
The measurements saved in the OTT ecoLog 800 (3G) are not lost after an
update.

18.2 Replacing the desiccant capsules
Recommended interval: Depending on the level of air humidity at the station,
e
very 12 to 24 months and when replacing the batteries.
There is a humidity indicator on the desiccant capsule.
When this indicator changes its color from blue to pink
the desiccant capsule has to be replaced, irrespective of
the time elapsed.
Quantity: 2 (1x pressure compensation capillary,
1x communication unit).
Notes
Store the desiccant capsule only in its original packaging.
Use only desiccant capsules that are fitted with a blue humidity indicator.
How to replace the desiccant capsules
A) Desiccant capsule for pressure compensation capillary
Open the top cap/observation well cover.
Pull and hold the communication unit approximately 1 m out of the observation
well (a second person would be useful).
Remove the screw fitting from the communication unit.
Slide the cap and pipe casing of the communication unit approx. 50 cm
towards the pressure probe cable. (The rubber stop located on the pressure
probe cable (refer to Fig. 2) prevents the pipe casing from falling.)

18.3 Checking/replacing the batteries
Refer to Chapter 5
18.4 Calibrating the conductivity sensor
The goal of the calibration is to determine the so-called "cell constant" for the conductivity sensor. To do this, it is necessary to check the zero point and to carry out
a conductivity measurement with a standardized calibration solution.
The cell constant – as well as the unchanging geometric measurements, the mate rials used and the construction of the conductivity sensor – takes account of the
aging process of the electrodes.
Recommended interval: every 12 months (after every cleaning)
with difficult local measuring conditions (heavy deposits):
as required every 4 to 6 months
Required accessories: standardized calibration solution, calibration container
(see Chapter 2, "Order numbers")
Communication unit

m
enu.
Press the "Start zero point test" button. The operating program starts an instan-
taneous value measurement and updates this every 5 to 6 seconds. If the measurement result displayed (blue triangle) is not in the green area ➝ clean the
conductivity sensor again and dry it well.
Press the "End zero point test" button.
Select the calibration solution used. Alternatively, select "Other ..." and enter
the appropriate conductivity value.
Add the calibration solution to the calibration container (filling height approx. 3/4).
Place the OTT ecoLog 800 (3G) into the calibration container (screw-on cover
in place) and tighten the screw-on cover by hand. Caution: There must not be
any air bubbles in the slot of the conductivity sensor! If necessary, lightly shake
the calibration container.
Press the "Start calibration" button. The operating program starts the instan -
taneous value measurement again and continuously updates it.
Wait until the values for conductivity and temperature do not change for sever-
al updates. The operating program displays the current and newly calculated
cell constant. Caution: Temperature values shown in red ➝ the conductivity
sensor is not at the temperature of the calibration solution! New cell constant
shown in red ➝ the cell constant lies outside the valid range.
Press the "End calibration" button.
Confirm the resulting question: "Save new cell constant?":
– cell constant is within the tolerance range ➝ "No"
(conductivity value is in the green area)
– Cell constant is outside the tolerance range and within the valid range ➝
"Yes" (conductivity value is in red area + current cell constant is shown in
black)
If the cell constant is outside the valid range ➝ error message.
Close the operating program.
Rinse the pressure probe thoroughly with clear water!
Reinstall OTT ecoLog 800 (3G) (see Chapter 8).
Determine current reference value with a contact gauge and enter it
(see Chapter 9.4 or 10).
Close the top cap/observation well cover.
Dispose of the used calibration solution!
Notes
Only use the calibration solution once!
Always store the calibration solution in a closed container! (The carbon dioxide
in the surrounding air and evaporation can change the conductivity value.)
Avoid water entering the calibration solution! Always dry the calibration con-
tainer carefully after calibration.
Calibration solution can be disposed of in the normal public sewer system!
The OTT ecoLog 800 (3G) saves the last three cell constants in a history (see
"Advanced operation ...", channel "Conductivity").
