SquirrelView Plus Software

SquirrelView Plus has all the features of SquirrelView with the additional benefits of allowing graphical analysis of historical and on-line data, whilst providing advanced reporting options.

SquirrelView Plus allows quick and easily analysis of the Squirrel data in a familiar Explorer navigation-style interface.

Data can be displayed with two different auto scaling Y-axes ─ essential for displaying widely varying data from different sensors on one graph. Particular data of interest can be zoomed into whilst an on-screen cursor can pick out exact values. Data can be shown in a statistical summary with set high and low alarm thresholds. The powerful calculation function allows the creation of “virtual” new channels from existing channels e.g. value from channel 1 added to the average of 10 readings from channel 2 etc.

SquirrelView Plus also incorporates a flexible report generation facility which allows the creation of custom report consisting of a title page with descriptive text, headers and footers, graphs, tabular lists of data, statistics and Squirrel logger set-up information. These can be saved as templates with any of these combinations saving time when preparing similar presentations of data.

Key features

  • 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. a pump switching on
  • Quick Graph function lets you quickly and easily view large data files
  • Wizards for easy set-up of communications and data export
  • Ability to send real time metered data from the Squirrel directly into Excel
  • Downloader for automating data download using MS Scheduler® (Squirrel 2010, 2020 and 2040 only).
  • Fully configurable data views
  • Flexible zoom feature including X and Y axes
  • Customisable report facility: print out graphs, readings, etc.
  • Tolerance curve
  • Calculated channels
  • Product cure calculation
  • Display oven profiles and oven zones
