Turbotrac operation is controlled from the Microtrac FLEX operating system. Feeder START, STOP, SEND HOME and CLEAN functions can be controlled by simply clicking on the relevant icon on the main FLEX screen. The Turbotrac Autoscan function allows the user to perform a full particle size analysis by simply clicking the AUTO icon to initialize the sequence. The sample to be measured is laid evenly on the sample tray. On starting the sequence the system invites the user to identify the sample by providing the relevant sample ID. Subsequently the vacuum system is activated followed by the activation of the pressurised airstream, both of which are controlled by internal valves.

A background check is then initiated to ensure the system is clean and to ensure validity of the analysis. The measurement cycle is started and the aspirator travels the length of the sample tray carrying the sample to the eductor. Microtrac performs the sample analysis and saves the data to the previously selected database. The pressurised airstream is turned off, followed by the vacuum system and the Turbotrac is then ready for the next measurement sequence.
