SquirrelView & SquirrelView Plus Sofware

SquirrelView is a universal software package that is included with every new Grant Squirrel data logger.

Its intuitive, user friendly, spreadsheet style interface allows quick set-up of the data logger for any application, speedy download of data and direct export to Excel™. SquirrelView Plus gives additional benefits such as graphical data analyses and advanced reporting options.

Minimum PC specification: – Windows® XP, Vista or Windows 7; Pentium II 266MHz; 60Mb hard disk space and 1 CD drive, colour SVGA screen (1024x768 recommended), at least one RS232 or one USB port, mouse.

Key feature

• Intuitive, user friendly spreadsheet style setup allows quick logger configuration in any application
• Flexible data presentation allows you to quickly display and analyse real time or historical
data as a line graph, bar chart or analogue gauge
• Graphical alarm and event identification lets you easily identify occurrences around specific analogue or digital events e.g. pump coming on
• Quick Graph function lets you quickly and easily view large data files
• Export data into Excel™ in real time, or as a CSV file for customisable data analysis
• Easily view and control the logger status from one single screen
• Use the simple communication wizard for hassle free working with modems, Ethernet, GSM, etc.
• Download data by date, time or events, saving time when working via modem or looking for specific data
• Save settings on the PC for efficient re-use
• Protect your data and set-up configurations with the security function

SquirrelView Plus-Analysis

SquirrelView Plus lets you quickly and easily analyse the data from your Squirrel data logger in a familiar Explorer™ style interface. Data can be displayed with 2 different auto scaling Y-axes. This is particularly useful when displaying widely varying data from different sensors on one graph. You can also zoom in on areas of interest, use a cursor to pick out exact values, times and dates, get a statistical summary of your data, set high and low alarm thresholds and, using the calculation function, you can create new virtual channels from existing channels.

SquirrelView Plus also incorporates a report generation facility, which allows you to create custom report templates consisting of a title page with descriptive text, headers and footers, graphs, tabular list of data, statistics and data logger setup information. Templates can be setup with any of these combinations and saves time when preparing similar presentations of data.

Please note: SQ2020 is supplied with software, manual, USB cable, wall bracket, batteries and 4 current shunt resistors.
