MeterGrapherM (MGM) downloads and analyses data from a CDI meter fitted with the Memory Option (-MEM). This Option:
Users can install meters in a variety of locations, and visit them periodically to download their data to the MGM laptop for analysis and transmission to other systems.
MGM can change the default configuration for each meter.
Note that you can install and try the software at no charge, ahead of buying meters – the first installation includes sample files so you can gauge the calibre of the graphing and File Management, including export to other systems.
