12. for communication database management calculation and analysis WinLog is designed primarily for occasional measurements with a limited number of sensors The program is based on a work method in which one or several measuring instruments are equipped with measuring sensors and placed out in the field during a limited time period The instrument is then connected directly to a PC and the collected information downloaded to the computer for presentation The concept behind WinLog is that you can quickly without significant installation present a measuring result in a time chart with key statistics This simplicity does not compromise the program s functionality Other Mitec software Mitec Monitor includes all the functionality of WinLog but has much more powerful functions for communication and data collection Monitor can communicate using different types of modem and can also collect data automatically This means that Monitor should be used for larger projects with longer duration and where measuring equipment may be spread geographically Monitor has even more powerful analysis tools with X Y diagrams macro functions etc Monitor can directly use measuring data stored by the less powerful programs WinSat and WinLog WinSat is designed specifically for Mitec s SatelLite range of data loggers WinSat has a limited number of functions and is suited to more simple measurements Measuring data from WinSat can be directly use
