4 Introduction
The OTT Orpheus Mini groundwater datalogger provides precise measurement
and recording of groundwater levels and temperatures.
The pressure probe equiped with a relative pressure measuring cell uses the
hydrostatic pressure of the water column to determine the water level. A pressure
compensation capillary in the pressure probe cable gives the measuring cell the
current ambient air pressure as a reference. Erroneous measurement results due
to atmospheric air pressure fluctuations are thus eliminated.
The OTT Orpheus Mini is available with 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)
With the help of a reference value that is input during startup, the OTT Orpheus
Mini's standard 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 adjusted with the "OTT Orpheus Mini 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 operator interface. The
basic operator interface allows all settings to be adjusted within a single program
window. In the advanced operator interface, the sample interval can be controlled through limit events, for example. The software also supports the execution
of pump tests.
The stored measured values are made available through an infrared interface
(IrDA) for wireless readout by a PC with OTT Orpheus Mini operating program or
OTT Hydras 3 or by a PDA with OTT Hydras 3 Pocket.
Together with an OTT ITC intelligent top cap (accessory), remote data transfer
and remote parameter input is possible via the GSM mobile telephone network
(GSM = global system for mobile communications). The remote data transfer can
be optionally carried out by SMS text messages or using the packet oriented
mobile radio transmission service GPRS (general packet radio service).
The OTT Orpheus Mini is installed simply by hanging it in observation wells of 1"
in diameter and above. Various adapters/suspension brackets are available as
accessories for this purpose. Three 1.5 V lithium batteries (type AA) provide an
operating life of over five years (sample interval: 1 hour; system length: 50 m).
Alternatively, alkaline batteries with a limited working life can be used.
The communication unit of the OTT Orpheus Mini can withstand temporary flooding (for details, see Chapter 21, "Technical data").

ment station with the OTT Orpheus Mini.
The OTT Orpheus Mini essentially consists
of three components: communication unit,
pressure probe cable and pressure probe
with datalogger.
OTT Orpheus Mini system length = length of
communication unit + cable length + length
of pressure probe with datalogger. (The
system length is required when ordering
an OTT Orpheus Mini. When setting the
OTT Orpheus Mini operating parameters
the system length is not required.)
(The rubber stop attached to the pressure
probe cable prevents the pipe casing from

5 Installing, checking and replacing batteries
Please note
Only use the battery types specified (no rechargeable types).
Always use brand new batteries. Do not mix used and new batteries.
Do not mix batteries from different manufacturers.
Do not mix lithium and alkaline batteries.
Properly dispose of dead batteries. Do not put in household waste.
Suitable battery types
3 x 1.5 V AA cells (LR6/FR6),
alkaline or lithium design (LiFeS; Energizer L91)
Insert the batteries as follows
Slide the pipe casing of the communication unit approximately 30 cm in the
direction of the pressure probe cable.
Insert 3 batteries (LR6/FR6 · AA) in the battery compartment as shown in
Figure
2. Ensure that the polarity is correct!
Slide the pipe casing of the communication unit back on until it stops.
Notes
The OTT Orpheus Mini begins measurements within a few seconds of the
batteries being inserted (there is no on/off switch).
If the OTT Orpheus Mini is to be taken out of service ➝ remove the batteries.
This will prevent the batteries from draining prematurely and will stop any
recording of unusable measurements.
When bringing back into operation it takes – dependent on how much data is
stored – up to 7 minutes before the OTT Orpheus Mini begins measurements
again.

Battery lifetime
With a sample interval of 1 hour and 50 m system length (without OTT ITC)
Lithium batteries: at least 5 years
Alkaline batteries: at least 1.5 years (high quality battery types)
Note
At 0 °C, alkaline batteries drop to approximately 50 % of their original 20 °C
capacity and at –10 °C they drop to approximately 35 % due to their design.
If temperatures drop below 0 °C at the measurement station, it is recommended
that lithium batteries be used.
Check the battery voltage as follows
Set up the PC/OTT Orpheus Mini communication link (see Chapter 7.2).
Select the "OTT Orpheus Mini" menu, "View Instantaneous values" function
1)
➝ the OTT Orpheus Mini starts an instantaneous value measurement ➝ the
"Observer" window indicates the current battery voltage and the energy
consumed from the batteries so far in Ah.
If the battery voltage is ≤ 3.5 to 3.6 volts ➝ replace the batteries.
Click on the "Exit" button.
Close the operating program.
1)
If set appropriately (Menu "File", function "Options"), the operating program starts at the
same time the "Observer" window is opened.
Replace dead batteries as follows
Open the top cap/observation well cover.
Pull the communication unit approximately 80 cm out of the observation well
and hold (a second person would be useful).
Slide the pipe casing of the communication unit approximately 30 cm in the
direction of the pressure probe cable. (The rubber stop located on the pressure
probe cable (see Fig. 1) prevents the pipe casing from falling. Do not move the
rubber stop!)
Remove dead batteries.
Insert 3 new batteries (LR6/FR6 · AA) into the battery compartment as shown
in Figure 2 within 10 minutes. Ensure that the polarity is correct!
Slide the pipe casing of the communication unit back on until it stops.
Slowly and carefully replace the communication unit in the observation well.
Close the top cap/observation well cover.
Notes
The OTT Orpheus Mini stores the measured values in a non-volatile memory.
There is no loss of data when changing batteries.
This also applies to storage without batteries over a long timespan.
If it takes longer than approx. 10 minutes to replace dead batteries, the time
(and possibly the date) will have to be re-entered (see Chapter13, "Date and
time settings"). Furthermore, it takes – dependent on how much data is stored –
up to 7minutes until the OTT Orpheus Mini begins measurement again.
When replacing the batteries, we recommend changing the desiccant capsules
at the same time (see Chapter 16.2, "Replacing the desiccant capsules").

7.5 Importing/exporting the OTT Orpheus Mini configuration
To transfer an Orpheus Mini configuration via diskette or e-mail, for example, the
functions Import/Export are available. Likewise, a configuration can be sent via
Export as an XML file to the OTT Hydras 3 user software. In the process, the OTT
Hydras 3 user software applies all of the measurement station/sensor configurations to an OTT Hydras 3 operating range.
Available export/import formats
Export ("BIN" file)
Export to a text file
Export for the OTT Hydras 3 user software
Import ("BIN" file)
The operating program stores all the necessary data of a configuration depending
on the export type in its own "*.BIN", "*.TXT" or "*.XML" file.
To export a configuration ("
*
.BIN" file)
This export type is required to transfer an OTT Orpheus Mini configuration as a
"
*
.BIN" file. The configuration can be read back into the OTT Orpheus Mini oper-
ating program via the "Import configuration" function.
Select the "Configuration Export" function in the "File" menu.
In the "OTT Orpheus Mini – export configuration" window, edit the file name
if necessary, select the memory location and click on "Store" ➝ the operating
program stores the configuration in a "*.BIN" file.
Note
The file name of the "*.BIN" file is arbitrary. The operating program suggests
a combination of station number and station name.
To export a configuration (text file)
This export type is required to transfer an OTT Orpheus Mini configuration for
documentation purposes as a "*.TXT" file. This "*.TXT" file can be opened with
any text editor or text processing program.
Select the "Export Textfile" function in the "File" menu.
In the "OTT Orpheus Mini – Configuration" window, edit the file name if neces-
sary, select the memory location and click on "Store" ➝ the operating program
stores 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.
Page 24
24
To export a configuration (OTT Hydras 3)
This export type is required to transfer an OTT Orpheus Mini configuration to the
OTT Hydras 3 application software. This "*.XML" file is read in via the Hydras 3
function "File", "Import Station Configuration (XML)".
Select the "Export Hydras 3 (XML)" function in the "File" menu.
In the "OTT Orpheus Mini – XML configuration" window, check the file name,
select the memory location and click on "Store" ➝ the operating program
stores 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 measurement station number and measurement station name along
with the ending "*.STATION.XML".
To import a configuration
Select the "Import Configuration" function in the "File" menu.
For an already opened configuration, confirm "Ignore changes?" message with
"Yes" (if necessary, save configuration previously).
In the "OTT Orpheus Mini – Configuration Import" window, select the appro-
priate "*.BIN" file and click on "Open" ➝ the operating program reads in the
configuration from the *.BIN" file. (Prior to this, save any configuration that is
already open).

8 Determining and displaying instantaneous values
(Observer function)
The operating program has a so-called "Observer" to enable the determination
and display of instantaneous values. The Observer also makes it possible to enter
a manually determined measurement, e.g. contact gauge value, into the data logger (Observer registration).
Various options can be set concerning the observer:
Selection possibility in the start window of the OTT Orpheus Mini operating
program:
– Direct and exclusive calling of 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 the
input of an observer registration
Set the Observer options as follows
Start the OTT Orpheus Mini operating program.
Select the "Options" function in the "File" menu. (If the option dialog cannot
be called, a password must first be entered. See Chapter 12)
Activate 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)
– Suppress display of instantaneous value before input
Click on the "OK" button.
The combination of "Only observer mode" with a password protects the operating
program against unauthorized input of operating parameters.
The "Advanced operation ..." option displays an additional button in the window
for setting the operating parameters.
Fig. 14: Input window to establish
options for the observer.
For further information on protecting the
OTT Orpheus Mini operating program with
a password, see Chapter 12.
Page 26

Set up the PC/OTT Orpheus Mini communication link (see Chapter 7.2).
Depending on the option set: In the start window of the OTT Orpheus Mini
operating program, either select "View Instantaneous values" or "Setup Device"
and in the subsequent window select the "View Instataneous values" function in
the "OTT Orpheus Mini" menu ➝ the OTT Orpheus Mini starts an instantaneous value measurement and the "Observer" window opens:
If necessary: Input Observer registration into the entry field of the pressure
sensor and click on the "Store" button.
If necessary: Start new instantaneous value measurement: click on the "Refresh"
button (" Automatic refresh" starts an instantaneous value measurement
every 5 seconds).
End the Observer: click on the "Exit" button and close the OTT Orpheus Mini
operating program.
Notes
The OTT Orpheus Mini stores each call of the Observer function in an info
channel with the date and time of day. After reading in and accepting into the
OTT Hydras 3 user software, this information can be displayed in the evaluation window of a sensor using the "Info Data" > "Station" > Show" function
("Observer registration general"). They are likewise visible via the "View/Export
data" > "Table" function of the OTT Orpheus Mini operating program.
If the " Do not calculate manual input value with scaling" check box in the
"Options" window is activated, the OTT Orpheus Mini also stores the input
check value, as well as the current instantaneous value. After reading in and
accepting into the OTT Hydras 3 user software, this information can be displayed in the evaluation window of a sensor using the "Info Data" > "Sensor" >
"Show" function ("Observer registration with check value). They are likewise
visible via the "View/Export data" > "Table" function of the OTT Orpheus Mini
oper ating program.

13 Date and time settings
The internal clock of the OTT Orpheus Mini is a high-accuracy, real-time clock. It
runs as soon as batteries are installed in the OTT Orpheus Mini. After the batteries
are removed, the clock will continue to run for approximately 10 more minutes.
For longer periods of power interruption, the OTT Orpheus Mini loses the date
and time. When batteries are re-installed, the OTT Orpheus Mini assumes the date
and time of the last stored measured value, with one minute added to the stored
time. The date and time are set using the OTT Orpheus Mini operating program.
Set the date and time as follows
Start the OTT Orpheus Mini operating program.
Set up the PC/OTT Orpheus Mini communication link (see Chapter 7.2).
Click on the "Setup Device" button in the start window.
Select the "Date/time" function in the "OTT Orpheus Mini" menu (alternatively:

Click on the "Setup Device" button in the start window.
Select the "Delete data memory" function in the "OTT Orpheus Mini" menu.
Acknowledge the warning "Are you sure you want to delete data memory?"
with "Yes" ➝ the operating program deletes the complete data memory of the
OTT Orpheus Mini (all measurement channels including the info channel). The
OTT Orpheus Mini then determines and stores the water level and the water
temperature again using the sample interval settings set.
15 Updating OTT Orpheus Mini firmware
If required, you have the possibility to update the OTT Orpheus Mini firmware
(operating system). This makes sense if, for example, devices delivered at different
times are to receive the same operating system version. Updating is carried out
via the OTT Orpheus Mini operating program. According to availability, an
updated version of the OTT Orpheus Mini 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. "spl01m_V1.40.1.bin")
from the internet site.
Move the file "spl01m_VX.XX.X.bin" to the directory in which the
OTT Orpheus Mini operating program is located.
Set up the PC/OTT Orpheus Mini communication link (see Chapter 7.2).
Select the "Firmware update" function in the "OTT Orpheus Mini" menu.
Confirm message with "Yes" ➝ the operating program copies the new
firmware to the OTT Orpheus Mini. The OTT Orpheus Mini then determines
and stores the water level and the water temperature again using the sample
interval settings set.
Caution: During the update, avoid breaking the communication link (e.g by
accidentally removing the OTT DuoLink from the infrared interface of the
OTT Orpheus Mini.) If the communication link is broken, the firmware will no
longer run! In the same way, 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 manually select
the required file.
The measurements saved in the OTT Orpheus Mini are not lost after an update.
