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 USB drive into the USB port of your computer, open the USB drive
window and run the .exe program.
4. Follow the on screen installation wizard
3.2 Connecting your Squirrel 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)
4. Wi-fi (where fitted)
Please see below for more information.
Serial (RS232)
For information on using serial adaptors please see the SquirrelView help file. If using a

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.
Important Notes on Setup using the Control Panel
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
Full setup capabilities of the 2020/2040 are provided using the SquirrelView software
provide. When using the control panel a few important points should noted:-
