    Before You Begin 1.3.3 Implementation overview A typical Model 3711 gas measurement system is configured to write measurement data to history at minute, hourly, daily, and user-specified intervals. The history data is then delivered to an external system for various accounting and analysis procedures. The delivery interval is controlled by the user. The event and alarm logs contain information related to configuration changes and various system conditions.
