 To scroll backward to a previously stored reading, press the DOWN key
VIEW STATISTICS
 Press the UP key
until the display reads “Statistics?
 If you have stored readings in more than one batch, the meter will display the current grain.
To view statistics of another grain with stored readings, press the UP key until the desired
batch is displayed.
 After you have selected the batch, press the ENTER key . The display will cycle through
the following statistics:
1.
Total: Avg.:
The meter displays the total number of readings stored for the selected batch, and the
average of those stored readings.
2. Std. Dev Co Var.
The meter displays the standard deviation for the readings stored in the selected batch,
and the co-efficient of variation. Definition of standard deviation and co-efficient of
variance is as follows:
Standard Deviation is a statistical parameter that gives the user, in one single figure, an
indication of the “range” of readings that make up the AVERAGE. The lower the
standard deviation, the closer all readings are to the average, indicating a uniform
distribution of moisture content throughout the batch or load.
Cov or co-efficient of variation is a term used to express the standard deviation as a
percentage of the average. Its values are between 0.0 and 1.0 and again, a low COV
would indicate a more uniform distribution of moisture.
3. Low High
The meter displays the lowest and highest reading for the stored readings in the selected
batch.
TO CLEAR MEMORY:
This function allows you to clear the stored readings, while maintaining all other settings such as
grain, temperature, mode, etc.
