Setting Up Measurement
Definitions
The topics in this section describe setting up different types of measurement
definition in Emonitor for your data collector. The topics describe the way
Emonitor works with the Enpac Ex for each different type of measurement
definition.These include answers to questions such as:
• How does Emonitor handle measurement units and alarms available in
Emonitor but not supported in the Enpac Ex?
• How many orders of magnitude and phase can the Enpac Ex collect?
• How does the Enpac Ex support collecting a spectrum when a
magnitude measurement is in alarm?
Emonitor combines measurement definitions when it creates a load file from a
list of measurement definitions. For example, Emonitor can combine the
measurement definitions at a location so that the data collector collects all the
measurements at one time. This makes data collection faster and more
efficient since you do not have to start each measurement individually. For
more general information on setting up measurement definitions, see the
Emonitor online help.
Magnitude Measurement Definitions
Emonitor and the Enpac Ex support magnitude measurement definitions.
This topic lists the unique characteristics of the Enpac Ex that you may need
to know when setting up and collecting magnitude data.
Measurement units not supported in the Enpac Ex
• Magnitude measurement definitions with unit not supported by the
Enpac Ex map to units of USER (eus) in the data collector. This results
in a process (DC) voltage measurement.
• For a list of supported measurement units, see Measurement Units on
Magnitude alarms in the Enpac Ex
• The Enpac Ex supports above, below, in window, and out of window
magnitude alarms.
• You must set Trigger to "Yes" for any magnitude alarms you want to
appear in the Enpac Ex during data collection.
