4 General information
The OMYL series consists of a large variety of loggers:
Some have an internal sensor only. Others have inputs for external sensors, while
some have both sensor types.
A full list of models can be found on our website.
The logger uses sensor inputs to which external sensors are connected. Some of the
sensors are combined sensors, such as the OMYL-RHT for measuring temperature
and humidity. This sensor uses a single input connector.
The loggers have a memory capacity for 100,000 readings which can optionally be
extended to 4,000,000 readings.
Logging can be set to either “stop-when-full” or” ring-buffer mode” (continuous mode).
The device can be controlled over the USB interface using OmegaView Software. It
only a few clicks to select the relevant parameters

4.1 Installing the batteries
The logger’s power supply is provided by a 3.0V lithium battery CR2477N (OMYLBATT).
Optionally for high-temp-applications a CR2450HT (OMYL-BATT-HT) battery can be
supplied.
The device offers internal battery monitoring. Om egaView will indicate when the battery
will require replacing. In addition, the LED flashing periodically indicates the need for
the battery to be replaced (see chapter 9, understanding LEDs for further information).
In order to insert a battery into the datalogger, unscrew the back cover of the logger
then insert the battery keeping the correct polarity – negative pole downwards.
When the battery has been fitted after a few
seconds the LED on the front of the logger will
start flashing in red/green/blue to indicate it is
operating.
The battery life depends mainly on the logging

interval selected. The table gives an overview for
typical intervals.
Some other factors reduce battery lif e. E.g., low temperatures decreas e battery lif e.
Downloading data or oper ation in MeterMode will als o cause an increased energy
consumption, which further decreas es battery life.

6 Logger Identification
By moving the mouse pointer across a picture of
a logger, a prompt will appear to click once or
twice on that picture.
By clicking once, further information will appear
to identify the logger.
A serial number, the Short ID, Date Code,
Description as well as the manufacturers name
will be displayed.
If more than one logger is connected, double click
on the particular logger to enable communication.
This highlights the chosen logger.
Now the logger has been selected further information is available.
Click once on the logger’s picture to show additional information about the logger model and
status.
31436 V1 OmegaView
Page 10 Operating Manual
Page 13
The full serial number, logger status, number of channels, firmware version,
battery capacity, memory percentage used and the actual logger time will be
displayed.
Logger Status gives information about the status of the logger. If the status is
“sleeping”, no readings are being taken and the logger is waiting to be ‘set’ to log.
If the status is “logging” the interval set will also be displayed.
The battery voltage is an indication of the battery life remaining. It is recommended
keeping track of the battery usage or simply use a new one if the status of the battery
is unknown and data is important. Refer to table in chapter 4.1 to understand the
impact of the interval on the battery life. The logger works with a lithium batt ery whose
life isn’t easy to predict. A brand new battery has a capacity of 3.0 V. A completely worn
battery has less than 2.5V. The logger also predicts battery life which is indicated on
the LEDs. Please refer to chapter 0 to understand the meanings of the LEDs .
Memory % shows the memory capacity used.
Note, that stored readings are overwritten when the logger is set to start logging.
Actual Time shows the loggers´ time. The logger automatically synchronizes its logger
time with the PC time when it is starts logging.

7.5.13 Soil moisture sensor - Decagon series (OMYL-M90 only)
The OMYL-SMP probes can be connected to the OMYL-M90 for measuring soil mois-
ture.
The sensors of the OMYL-SMP series are capacitive sensors for soil moisture that
measure the permittivity of soil. An output signal proportional to the soil moisture is
created by alteri ng the sensor’s reference voltage. The significant differences between
the permittivity of water (ca. 80), soil (ca. 4) and air (ca. 1) are beneficial in the
measuring principle as the changes in moisture content, result in a large change in the
permittivity of the soil.
The influences of the soil’s temperature and salinity are minimized by the specialist
surface coating of the sensor.
Specifications:
OMYL-SMP-2
Measuring range: 0-saturation
Accuracy: <0,03m³/m³ for all soils, up to 8 dS/m
With soil specifi c calibration: +/-0,02 ³/m ³ (+/-2%)
Resolution: 0,001 m³/m³ VWC in mineral soils. 0,25% in natural soil
Operating temperature range: -40-60°C
Selecting the measuring site
When selecting the site to measure be aware that the immediate surrounding area of
the sensor has the most influence on the readings.
For exam ple, holes, cavities, and compactions can have an effect on the
measurements.
Do not install the sensor near large metal objects as this can affect the magnetic field
surrounding the sensor.
Please be aware of objects (such as sticks and stones) between the sensor brackets
as these may affect the measurements.
When installing the sensor please make sure that the contact areas between the
sensor and the soil are maximized.
Two methods can be helpful in siting the sensor:

Installing the OMYL-SMP-2
1. The installation of the OMYL-SMP-2 is especially easy to manage. After digging a
sufficiently deep hole for the sensor, insert the brackets into unspoiled
tom or side of the hole.
The sensor needs to be entirely covered, including the rubber over molding.
If it’s too difficult to insert the sensor, try to loosen the ground. DO NOT drive the
sensor into the soil by force, as this may cause irreparable damage.
2. Carefully refill the hole. Try to prevent the rubber-coating segment from being bent
as this may cause damage.
Position of the sensor
The sensor can be operated in any position, but the installation at right angles to the
surface is preferable in order not to impede infiltration.
Removing the sensor
NEVER pull the sensor’s cable if to remove it from the ground. This could damage the
device.

7.7 Display logged data as a graph
Click here or go to Data/Gr aph to display readings as a graph.
Select the file to be graphed.
OmegaView automatically searches its predefined folder:
C:\Users\Public\Public Documents\Graphtool.
As soon as the data has been fully processed the GraphTool-Software will pop up.
When purchasing the OmegaView Plus
software there will be a serial number
and two keys which are required to be
entered here. The graphing option will
appear if these have already be entered.
The software can be upgraded and new
options added at a later time. Contact
Omega to purchase an Om egaView Plus
license (OMYL-SOFT-PLUS).
7.8 Display logged data as a table
Click here or go to Data/Table to display data in a table.
Select the file for graphing.
OmegaView will automatically open the file and search for its predefined folder, which has been set in the preferences section.

8 Troubleshooting
Typical error messages that may occur during operation are listed below.
Try to solve the problem with the following help list before contacting Omega.
A) No logger is displayed
First, check if the logger cable is correctly connected to the USB Port
and to the logger. Secondly, uninstall the software and re-install the
complete package (software/USB-driver). Administration rights are
required during the installation process. If the problem still exists there
may be a fault with the logger.
B) Unknown Logger is displayed
The software being used may be an old version, which doesn’t
recognize the new hardware. Check with Omega for any upgrades.
C) Cannot contact logger
If the error message continues to show after checking that the loggers is
connected correctly and appears in the OmegaView software. This
could be due to the logger having a flat or missing battery. Replace the
battery and verify initial function test as follows:
After having inserted the battery the LED on logger front should flash in
all three colours (LED chaser). This shows the logger is operating. Now,
try contacting the logger. If problem still exists there may be a problem
with the logger hardware, contact Omega.
D) Logger stops taking readings after a period logging.
Please check the logger setup for any settings selected for a stop
date/time, change the setup if necessary. Otherwise this could be due to
a flat battery. Check battery voltage in OmegaView (see chapter 4.1)
and possibly replace battery.
E) Humidity/Temperature readings continuously show -40°C/+120°C .
Humidity/Temperature-Sensor is faulty or the cable has been damaged.
F) Other sensors continuously show their Max/Min:
Sensor or sensor cable could be damaged.

Important notes for measuring humidity
The OMYL humidity/temperature probes are a precise, reliable hum idity sensor element which has a good long-term stability. The capacitive sensor allows for humidity
measurement in many applications and will give stable readings in clean environments
for several years.
Depending on t he environm ental conditions the sensor can become contaminated by
for example: dust, chemicals and dirty water which will reduce the active life. There are
further limitations, the sensor may be used in a operating range of 0-100% RH this
operating range is reduced at as the operating temperature increases. See the graph
below. This is due to the fact that quite an aggressive environment is developed when
measuring high humidity and high temperature at the sam e time:
Operating conditions
Humidity
-- -- Normal/Range
-- -- Max. Range
Temperature
The sensor should not be damaged when condensation occurs occasionally. If condensation does occur, dry out the sensor in order to return to the correct m easurements, except the sensor polymer is contaminated with substances (see above).
If condensation occurs r egularly or for a long period of time, the sensor life is reduced.
If the sensor is even saturated it may give incorr ect readings in the range of 0-100%
RH (sometimes even negative readings), but will recover when water droplets have
evaporated.
To ensure high quality readings we therefore recommend that probes/loggers are verified and calibrated on an annual basis.
