Version SLM - Utility Software Programs


The SLM Utility Software Programs interface the Larson Davis Sound Level Meters Model types 720; 812; 820; SoundTrack LxT; 831 and System 824 with a PC and Printer. This enables the instruments to be controlled  from the PC, providing the facility of a large color screen to assist data measurement, instrument control and measurement interpretation. The instruments can be 'setup' from the PC via an Upload routine or 'setup' data can be transferred from the instruments to the PC via a Download routine. Measurement data from the instruments can be translated and used to create reports on the PC which can be exported in the form of Spreadsheets. Data bases can be created and upgraded as required.
