1. Open the battery cover by releasing the clip (highlighted)
2. Insert 2 C* 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.
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.

3. Installing Software and USB drivers
Select Continue Anyway on the Hardware Installation warning which refers to Windows
Logo testing.
If you experience any problems refer to Troubleshooting->20xx USB Drivers in
SquirrelView help

matically 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.
After installing the software connect the logger to the PC.
On detection of the logger the PC will install the Grant Instruments SQ20XX USB device
drivers
Win 7/Vista - USB Device Drivers are automatically installed and no further action is required
Important: Please ensure the software is installed before connecting the Squirrel data
logger.
* 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)
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 Grant 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

Setup useful.
4.1 Startup SquirrelView and Select Logger Type
Click on the shortcut icon on your desktop to launch SquirrelView or select it from your
start menu. When the SquirrelView Assistant is loaded, ensure the correct logger type
and communication method is selected.
Logger type can be viewed from the SquirrelView assistant, if you need to make any
changes select Logger Selection from the toolbar or run the Communication Wizard.
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:

In this screen you can now download the Data File and invoke the Export Wizard
or download the Data File via Analysis* (See page 10 for further information).
The data File is given a unique name
(e.g. 28162735.D20). An explanation of
the file name is shown on the right; this
shows the date and start time
In this example you will download and view the Data in the Analysis* window. Start by
selecting the Data File and Graph Data action, then click Download Selected File(s).
You will be prompted to save the Data file, then the data will be converted for viewing.
Once the decoding has
taken place the Analysis File
Description window will be
presented, click OK to view
your Data.
*Available with SquirrelView Plus only.

5. Download Process Explained
The Diagram above shows the download process. Data in the logger is written to the internal
memory and may be downloaded by SquirrelView.
Before the data can be viewed it must be converted by SquirrelView for Analysis or exported
to .csv or .xls format depending on the PC software being used.
The conversion process can be performed in one of three ways within SquirrelView:
 from SquirrelView assistant->Analysis->Export Data File
 automatically when using the download Data button from SquirrelView*
 or from the Logger Data Analysis screen by selecting File->Import Data*
Once the file has been downloaded it can be double clicked to open it with the program specified
under „Tools‟, „Preferences‟, „File Association Action‟.

The 2010 allows for the creation of a basic channel setup including logging interval,
sensor type and sensor power (excitation) if required via the graphical interface, A full
setup including more advanced features can be performed using the SquirrelView soft-
ware included. Below is a brief explanation of how to create a basic channel using the
graphical interface
6.3.1 Channel Setup
From the „Main Menu‟ choose the option
„Setup‟ then the option „Channel Setup‟.
6.3.2 Adding or Editing a Channel
Once in „Channel Setup‟ you can clear all
channels, add/edit a channel, view channel
details or delete a channel. Select „Add/Edit
Channel‟.
6.3.3 Adding a New Channel
The „Add/Edit Channel‟ menu shows channels
currently set as well as giving you the option to
add others. Select „Add Channel‟
6.3.4 Channel Setup
Select the channel Sensor Type, Range and,
if required, which Sensor Power (excitation)
time is to be used .
6.3.5 Viewing Channels Setup
Once you have finished adding your required
channels and details the wiring configuration
can be viewed using the „View Channels‟
option.
Note that Channel Descriptions are
automatically assigned based upon the
Sensor Type of the channel. This description
can be modified using SquirrelView if required.
6.3 Creating a basic Setup

Important Notes on Setup using the Control Panel
Full setup capabilities of the SQ2010 are provide using the SquirrelView software pro-
vide. When using the control panel a few important points should noted:-
6.3.6 Interval Setup
A setup created from the control panel will
assign all channels to the same logging
interval. To change or view this interval choose
„Intervals‟ from the main „Setup‟ menu.
6.3.6 Sensor Power Setup
The sensor power setup can be changed by
going to „Sensor Power‟ from within the main
„Setup‟ menu.
Whilst all channels are assigned to the same interval, Interval A, all intervals can be
viewed in the case of a more complex setup from SquirrelView
To avoid problems with wiring configuration, sensor types are not editable once set but
their range and sensor power requirements can be. Delete a channel if you require to
change its Sensor Type
If the number of sensors is exceeded when adding new channels, the message "Invalid
Setup" will be displayed
Calculated channels setup from SquirrelView will not be shown on the view channels
option
The reference junction can not be deleted while a sensor type that requires it for
correct operation is set up, e.g. a thermocouple
You cannot change a setup whilst the logger is armed
The message "Sub-Second rate" will be displayed when attempting to view or edit a
Sample Intervals that have been set to less than 1 second. Use Squirrelview Logger
Setup to view or edit the sub-second Intervals

7. Connections
As the wiring configuration is dependant upon the sensor type used, it is displayed in SquirrelView
during the setup. Follow the wiring diagram to attach the required sensor. If you would like to print
the diagrams in more detail or view at a later stage select „File > Print from Logger Setup‟.
