Table 4-4. Scan Statistics
Maximum measurement.
Minimum measurement.
Average of all the measurements taken.
A measure of the distribution of a set of data from its mean. The more spread
apart the data, the higher the deviation.
Difference between the Maximum and the Minimum.
A measure of how much the readings change over time.
The maximum number of channels that can be graphed at once is four.
Selection of two or more channels with different input types (such as
temperature and milliamps) can make the graph difficult to read because
they do not share the same unit. To prevent this, only select channels of the
same input type or view the channels one at a time.
