Data Sheet
Getting Started Guide

Communications - Wi-Fi, USB and RS232 serial ports are inbuilt. This allows simple connection to either a PC based TCP/IP network, a wireless to PC connection or to a GSM modem for remote data downloading. This flexibility enables global data access and retrieval as well as complete system integration of the SQ2020 2F8 into complex and critical applications.

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.

Software configuration via SquirrelView - The SquirrelView software (supplied with the SQ2020 Wi-Fi data logger) allows logger configuration, data download and export whilst giving the user full control over SQ2020. The optional SquirrelView Plus gives the used access to many advanced data analyses and archiving/transfer features. Refer to SquirrelView data sheet for specifications.

Concurrent sampling - The SQ2020 2F8 uses multiple analogue and digital converters that enables true concurrent sampling and logging. It Allows the user to configure a channel to log at a rate of 100Hz whilst retaining different sample speeds on the other channels. Ideal for measuring dynamic parameters that change at different rates such as temperature and pressure.
