2. Product Overview
The OM-93 logger is a portable wireless logger from Omega. The OM-93 logger can be connected either
via a USB cable to a Windows®PC application or using Bluetooth wireless technology to your iPhone®,
iPad®or iPad mini®. Both Windows®PC and iPhone®applications offer a simple means of configuring the
logger, data extraction and data viewing features.
Figure 1: Introducing the Omega OM-93 Logger, PC and iPhone applications
The OM-93 logger can be used for a number of transportation applications including:
sensitive/fragile items
food
animal/livestock
plants
chemicals
medicines or organs
It can also be used in situations where it is simply not convenient to make a cable connection to a
Windows®PC. Suppose for example you are storing some vaccines or chemicals in some environmental
chamber and would like to ensure temperature and humidity conditions are kept within acceptable levels

Revision 1.0.3 Page 4
over time. By mounting a OM-93 logger inside the chamber then one can periodically come near to the
chamber, connect to the logger from an iPhone®, download the most recent data, email the recorded
data and configure the logger to continue logging. This can happen wirelessly and without opening the
chamber and affecting environmental conditions.
The OM-93 logger operates in an ultra low power mode even when logging temperature and humidity and
can still be connected to wirelessly without any physical touching of the logger. The logger can operate in
this fashion for 6 months from a fully charged battery. The rechargeable battery may be charged either
by connection to USB on a computer or using a mains/USB power cable.
The OM-93 offers accurate and repeatable logging for temperature and relative humidity. Temperature is
measured to an accuracy of +0.3oC over the range +5oC to +60oC. Over the full range -20oC to +60oC
the accuracy is +2.0oC. Relative humidity is measured to an accuracy of +2.0% over 20% to 80%
humidity range and +3.0% over 0% to 100%. Both temperature and relative humidity are logged at a
user configurable logging rate which can be set in the PC application program or iPhone application.
Figure 2: OM-93 Alarm Indicators
When you would like to guarantee that conditions are within particular environmental limits then one can
also set operating ranges above or below which light indicators will be activated so that the user can
become aware that the desired environmental conditions have been exceeded.

4. Buttons and LED Indicators
The OM-93 logger includes one button located on the side of the logger. It is possible by configuration in
the PC or iPhone®application to use this button as a way to start and stop logging. See sections 6.11 and
7.4 of this User Manual regarding configuring for button press start.
Figure 4: OM-93 Logger Start/Stop Button
The logger contains three LED indicators with the following functionality:
Status LED
When the logger starts logging then this LED pulses green once for 1 second.
When logging this LED pulses green for 7 milliseconds and off for 6 seconds.
When the logger stops then this LED pulses red for 1 second then off forever.
Bluetooth Connected LED
This LED is blue when the logger is connected to a mobile device.
Alarm LED
When a temperature or humidity alarm is triggered this LED pulses red for 7 milliseconds and off
for 6 seconds.
When connected to USB cable this LED is red continuously when the logger is still charging and
green when fully charged.

Figure 6: OM-93 Logger Unit
One USB cable – type A to micro-USB type B
Figure 7: USB Cable

Revision 1.0.3 Page 8
6. USB Operation
The OM-93 logger can be configured, data downloaded and further analysed by connection to a PC or Mac
using a USB cable and the OM-90 Series Data Logger Software. The process for this is described in this
section. The logger can similarly be configured by the iPhone® wireless device application as described in
section 7.
6.1. Installation of the PC Application (Windows)
Installation of the OM-90 Series Data Logger Software is very simple. The OM-93 needs no special drivers
since it is a USB HID device and such devices can make use of the standard drivers that come with
Windows. The software is located on the included CD or can be downloaded from the Omega website.
The PC application is a single application that can support all OM-90 series loggers including the OM-91,
OM-92 and the OM-93.

Revision 1.0.3 Page 9
6.2. Front Page
When the OM-90 Series Data Logger Software is started the welcome screen appears and gives a brief
introduction to the OM-90 Series loggers and what they can be used for.
Click on the Configuration Wizard Button to start configuration of the logger.
Click on the View Logged Button if you want to view data graphically.
Click on the View Spreadsheet Button if you want to view logger data as a table.
Figure 8: OM-90 Series Data Logger Software

Revision 1.0.3 Page 10
6.3. Main Page
The main page of the application GUI consists of a configuration pane, a graphical pane and a
spreadsheet pane. It is possible to have any of these enabled or disabled by the buttons located top left
in the window. The panes will automatically start in an enabled or disabled view depending on the
viewing mode select from the front page.
Figure 9: PC Application Main Page
Buttons are also included for saving/loading configuration and logged data to and from file.
There is also a button for selection between Celsius or Fahrenheit temperature scales.
A connection indication on the right hand side becomes blue when your application is connected to a OM-
93 logger and is greyed-out otherwise.
Icons are provided for opening in Excel and for generating PDF reports.
Finally a home icon provides a link back to the front page.

6.5. Saving a Configuration File
Configurations can be saved to file so that you can use the configuration next time or if you have multiple
devices with the same configuration.
Saving a configuration file is just a matter of selecting the save icon and filling out the file name. If the
logger contains no logged data then it will only save the configuration settings. Configuration and logged
data is stored in Comma Separated Value (CSV) format.
Figure12:SavingaConfigurationtoFile

Revision 1.0.3 Page 14
6.6. Loading a Configuration from File
Loading a configuration file from disk is just a matter of selecting the open icon and selecting the
configuration file name. This upload presents a simple way to configure multiple loggers with the same
configuration. This ensures a common configuration and saves time/effort when configuring multiple
devices.
Figure13:LoadingaConfigurationfromFile
Remember to press the configuration button if you want the configuration data held in the GUI to be
written to your OM-93 logger.

Revision 1.0.3 Page 15
6.7. Retrieving Logged Data
Data can be retrieved from the logger by connecting to the logger and then pressing the read button at
the bottom left of the GUI.
Both the device configuration and logged data will immediately become uploaded and viewable in the
configuration, graphical and spreadsheet views.
Zooming in and out of the graphs can be achieved by the following controls:
To Zoom In - Drag the left mouse button
To Zoom Out - Click the right mouse button
When zoomed in you can move around using the key-board arrows or the mouse scroll wheel
To write data and configuration to file, press the save icon. Data and configuration is then stored in
Comma Separated Value (CSV) format which can be edited by third party software such as Microsoft
Excel or read back into the OM-90 Series Data Logger Software at a later point.
Figure14:SavingLoggedDatatoFile

Revision 1.0.3 Page 16
6.8. Viewing Logged Data from File
It is a simple matter to read back data from file (CSV format) into the GUI and view previous logs
graphically or using the spreadsheet views. Simply press the open icon and then select the file which you
would like to view.

6.9. Configuration of a OM-93 Logger (Start at Specified Time)
You can configure a device so that it starts at a specific time. Configure as per section 6.4 but select At
Specified Time. Fill in the exact month, day, hour, minute and seconds when you want the logging to
start.
Remember to write the setup to the logger by pressing the Configure Button.
When you have disconnected the logger and the time reaches the desired start time for the logging then
the logger will begin to log. This is a perfect way to have multiple loggers start logging at exactly the
same time.
