Definitions of terms used in statistical mode
For this purpose the individual readings are defined as
values x1, x2, xn, and xi is any data point:
-Statistical sample population, n- the current number of
stored readings on whichthe statistical analysis is based.
-Maximum (MAX) - the highest reading.
-Minimum (MIN) - the lowest reading.
-Mean (MEAN), - The sum of all readings divided by the
total number.
-Standard deviation (SD), s- Square root of the sum of
squared --deviations from the mean.
-Coefficient of variation (CV), c- Standard deviation
divided by the mean, a measure of data scatter.
Preferences
Changing the calibration value
The instrument is supplied with the assigned values of the
standard tile stored in the instrument memory.
These values are updated when the instrument is
recalibrated by an authorised service center.
The stored values can also be changed by the end user if an
alternative tile is to be used for calibration
Calibrate at low, medium or high gloss value
It is often desirable to calibrate using a standard that closely
matches the gloss of the samples to be tested.
Rhopoint supply a range of gloss, semi-gloss and matt tiles
to suit all applications. To calibrate the Novo-Gloss Trio using
a purchased tile, the calibration value in the instrument
memory must be adjusted to match the assigned value of the
new tile.
Rhopoint also supply mirror tiles for verification of measured
values at very high gloss levels. The instrument should not
be calibrated on a mirror tile.
