10.5 Using the density statistics
Separate statistics can be maintained for each method of density determination. All results (max. 651500) are saved which you accept
into the statistics when you perform density determinations.
Settings
For use of the statistics to be possible, the statistics function (section10.3.4) and the
two function keys “Result” and “CL Result” must be activated (section 10.3.6).
Note: In the example at left, no values have been accepted into the statistics yet. Because
of this, the two function keys “Result” and “CL Result” are inactive and cannot be used.
Recording values for the statistics
If the statistics function is activated, at the end of each density determination you are
asked whether you want to include the result in the statistics.
If you want to include the current measuring result in the statistics, press the “YES” key.
The result is then included in the statistics for the current method.
Inclusion of the result is confirmed in the display.
If you do not want to include the result in the statistics, press “No”. The result then stays
saved until the next measurement, but is not included in the statistics.
Displaying and printing statistics
Make sure you have selected the density determination method for which you want to
display or print statistics (section 10.3.2).
Press the “Result” function key to call up the statistics. Note: If there are no values in the
statistics, the key is shown gray and cannot be used.
The statistics window displays those values which you selected to be included in reports
of statistical data (section 10.3.8). The following values are selected at the factory:
“n”: Number of samples recorded in the current measurement
series
“x”: Average (mean) density of all recorded samples
“s”: Absolute standard deviation of the measurement series
“s. rel”: Relative standard deviation within the measurement series
“Min”: Lowest density value determined in the measurement series
“Max”: Highest density value determined in the measurement se-
ries
“Diff”: Difference between the largest and smallest density value
within the measurement series
