2.1 Installing the batteries

The OM-SQ2020/2040 uses six AA size alkaline batteries located under the remov­able cover shown below. To insert new or change the existing batteries:

1. Open the battery cover by pushing down and sliding as shown.

2. Insert six AA* batteries, ensuring the correct polarity.

3. Refit the battery cover

* It is recommended that all replacement batteries are of the same manufacturer, type
and condition.

2. General Information

2.2 Power indicator

Battery indicator
When logging please ensure that the batteries in the unit have sufficient capacity to
complete the logging task. This can be checked via the battery indicator located in the
top right of the display.

HIGH LOW
CAPACITY CAPACITY

External power indicator
The logger may be powered from an external source (10-18V DC)

Important: To ensure data protection in the case of an unexpected
power loss, please ensure that batteries are fitted whilst the unit is
operational.

3. Communicating with your Logger

3.1 Installing the Software

For detailed installation instructions please see the supplied ‘Software Installation Guide’

supplement. For quick installation please see the steps below;

1. Ensure you have administration rights on the PC you wish to install software on

2. Ensure any current OMEGA applications are closed

3. Insert the CD into the CD\DVD drive of your computer and wait for it to autorun*

4. Follow the on screen installation wizard

* If after a few minutes autorun has not occurred select the Run option from the Windows
Start Menu. In the Command Line box, type d:\setup and press enter (where d:\ is your
CD\DVD drive, modify if required)

Important: Please ensure the software is installed before connecting the
OM-SQ2020/2040 data logger.

3.2 Connecting your OM-SQ2020/2040 Data Logger

You can connect to your logger by using one of the following methods;

1. Serial (RS232), including serial adaptors

2. USB

3. Ethernet (where fitted)

Please see below for more information.

Serial (RS232)

For information on using serial adaptors please see the OMEGALOG® help file. If using a
straight serial (RS232) cable, connect one end to the serial port on the logger and the other
end to the PC’s serial port. Once connected you are ready to begin communications.

Version 1.2 - October 08 28923
Page 6

USB

Connect one end of the supplied USB lead to the USB port on the logger and the other end
to a USB port on the PC.

On detection of the logger the PC will launch the driver installation wizard.

Win 2000/XP - During the installation the USB drivers were pre-installed so the wizard will

automatically locate the driver. On the ‘Found New Hardware Wizard’ select ‘No, not this
time’ and for all the other screens select ‘Next’ to complete the installation.

28923 Version 1.2 - October 08

Page 7

Win 98SE - Select Search for the best driver for your device (Recommended), Click
Next and follow the instructions illustrated below.

Select Continue Anyway on the Hardware Installation warning which refers to Windows
Logo testing. Once the driver installation has completed you are ready to communicate to
your logger.

If you experience any problems refer to Troubleshooting->20XX USB Drivers in OMEGA­LOG® help.

Ethernet

Before using the Ethernet connection please read the configuration manual which can be

found under ‘~\OMEGALOG\Manuals\OM-SQ20XX Inbuilt Ethernet Configuration.pdf’
where ‘~\OMEGALOG’ is the installation directory of OMEGALOG®. Connect your Ethernet

network to the Ethernet port on the logger.

Ethernet is only available when the logger is connected via an external power
supply.

4. Quick Start Example

After installing OMEGALOG® an example setfile will be installed within the
OMEGALOG® installation directory. The example file will log the internal temperature of
the logger. In order to familiarise yourself with the logger the novice user may find this
example Setup useful.

4.1 Startup OMEGALOG® and Select Logger Type
Click on the shortcut icon on your desktop to launch OMEGALOG® or select it from
your start menu. When the OMEGALOG® Assistant is loaded, ensure the correct logger
Type and communication method is selected.
Logger type can be viewed from the OMEGALOG® Assistant, if you need to make any
changes select Logger Selection from the toolbar or run the Communication Wizard.
(Note: the default communication method is USB and you will need to change this via
the Communication Wizard if you are using any of the other communication methods).

4.2 Synchronise Logger & PC
It is advisable to start by synchronising the Logger clock with the PC clock. See step 1
and 2 below:

Synchronise clocks:
