The data remain there even in case of voltageinterruption.Up to 100,000 measured values can be stored in the sensor in a ringmemory. Each entry contains date/time as well as the respectivemeasured value. Storable values are for example:• Distance• Filling height• Percentage value• Lin. percent• Scaled• Current value• Meas. certainty• Electronics temperatureWhen the instrument is shipped, the measured value memory isactive and stores distance, measurement certainty and electronicstemperature every 3 minutes.In "Extended adjustment" you can select the respective measuredvalues.The requested values and recording conditions are set via a PC withPACTware/DTM or the control system with EDD. Data are thus readout and also reset.Up to 500 events are automatically stored with a time stamp in thesensor (non-deletable). Each entry contains date/time, event type,event description and value.
