Measurement definitions are controlled in part by the collection specification
(Setup > Collection). You select the collection specification when you set up the
measurement definition. You can create new collection specifications based on
your specific measurement by choosing Setup > Collection.
Figure 13 - Collection Specification Dialog Box
The transducer specification used in the collection specification includes both
the base unit and the calibration value.
Edit the Measurement Definitions
The Emonitor software does not allow you to change some of the information for
a measurement definition after you collect data for that measurement definition.
This prevents you from collecting and then comparing data with different
measurement definition selections. You cannot edit the Data Type or Units
columns in the Measurement Definition dialog box after you collect data You
can, however, change the Collection, Filter, and the Storage columns for a
measurement definition after collecting data.
IMPORTANT
The figures in a typical measurement setup in the following sections refer to
making selections in these dialog boxes. For example, a table for STD (HZ) 2000
collection specification would look like this.

Changing the collection specification can make it difficult to
compare data after the change with data before the change.
