During these periods Lower Limit Keep Time the probe would establish a value that is too low The Lower Limit Keep Time sets the maximum possible time where the probe could determine inaccurate too low measurement values Furthermore the passing or wiping of the probe head with metal blades or wipers can lead to the establishment of too high measurement values Filter Upper Limit The Upper Limit Keep Time sets the maximum possible time where the probe would determine inaccurate too high measurement values Using a complex algorithm SONO probes are able to filter out such faulty individual measurement values The standard settings in the Measurement Mode CA and CF for the filter functions depicted in the following have proven themselves to be useful for many applications and should only be altered for special applications It is appropriate to bridge material gaps in mode CA with Upper and Lower Limit Offsets and Keep Time For example the Lower Limit Offset could be adjusted with 296 with a Lower Limit Keep Time of 5 seconds If the SONO probe determines a moisture value which is 296 below the average moisture value with e g 8 than the average moisture value will be frozen at this value during the Lower Limit Keep Time of 5 seconds In this way the material gap can be bridged This powerful function inside the SONO probe works here as a highpass filter where the higher moisture values are used for building an average value and the lower
