If possible, the curve shouldbe saved with a low level in the vessel.With this, you can detect signal changes over the operating time. Withthe adjustment software PACTware and the PC, the high-resolutionecho curve can be displayed and used to compare the echo curve ofthe setup with the actual echo curve.The function "Echo curve memory" enables storing echo curves ofthe measurement.Under the sub-menu item "Echo curve memory" you can store thecurrent echo curve.Parameter settings for recording the echo curve and the settings ofthe echo curve itself can be carried out in the adjustment softwarePACTware.With the adjustment software PACTware and the PC the high-reso-lution echo curve can be displayed and used later on to assess thequality of the measurement.With the function "Proof test", the function of the instrument can bechecked on a recurring basis.During the function test, the safety function must be treated as unsafe.Keep in mind that the function test influences downstream connecteddevices.You can find detailed information on the proof test in the SafetyManual (SIL).In this menu item, the internal clock of the sensor is adjusted.Diagnostics - Echo curvememoryDiagnosis - Proof testAdditional adjustments -Date/Time
