space
The Squirrel 2040 series provide high performance universal data loggers packed with the same powerful features as the Squirrel 2020 series with additional high speed logging on up to four channels and twice as many universal input channels. This provides great flexibility to handle a wide range of complex and demanding multi-channel applications such as high-speed vehicle testing or engine monitoring.The Squirrel 2040 series are easy, fast and convenient to use – either as portable, stand-alone loggers or as PC-linked data acquisition systems in industrial testing and research, scientific and environmental research and quality assurance applications. Twin processors, multiple 24-bit A to D converters, up to 32 universal channels, removable Multi Media (MMC) or SD card memory and a choice of communications methods ensure that the Squirrel 2040 series provides state-of-the-art data logging and communication capability for sophisticated applications needs.
Concurrent sampling:
The SQ2040 series uses multiple analogue to digital converters that enables true concurrent sampling and logging. This allows the user to configure up to 4 channels to log at a rate of 100Hz , while retaining different sample speeds on other channels. This makes the SQ2040 series ideal for measuring dynamic parameters that change at different rates such as temperature and pressure
Multiple configurations stored in the logger:
Up to six logger configurations (channel type, names, logging speeds, triggers etc), together with the current configuration, can be held in the logger’s internal memory. Additional configuration settings can also be loaded from the external MMC/SD memory card. This allows the operator to quickly and easily switch between logger configurations without the need for a PC.
Communications:
Ethernet, USB and RS232 serial ports are built-in. This allows quick connection to either a PC based TCP/IP network, a wireless to PC connection or to a modem for remote data downloading. This flexibility enables global data access and retrieval as well as complete system integration of the SQ2040 series into complex and critical applications
Comprehensive software configuration via SquirrelView:
The SquirrelView software (supplied with the SQ2040 series data loggers) allows logger configuration, data download and data export whilst giving the user full control over the SQ2040. The optional SquirrelView Plus gives the user access to many advanced data analysis and data archiving/transfer features. Please refer to our separate SquirrelView data sheet for all its advanced features.

General Overview
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.
