60 Setting Up Measurements
several factors. In general, however, Emonitor can combine measurement
definitions at the same location when they have the same:
• Measurement units (part of the measurement definition)
• Measurement filter (part of the measurement definition)
• Transducer calibration and input type (from the transducer specification
used in the measurement definition’s collection specification)
In addition, there are some specialized cases that allow or prevent Emonitor
from combining measurement definitions from the same location when they
meet the above conditions.
• In general, Emonitor cannot combine a magnitude and a spectrum
measurement if they have different measurement filters.
• Emonitor can combine an envelope acceleration magnitude
measurement with a spectrum with the same units.
• Emonitor can combine a non-filtered measurement definition with a
high pass, low pass, or band filtered measurement when the band filter is
applied by Emonitor after the spectrum is unloaded.
• Emonitor can combine two signatures if they are the same type (time,
fixed frequency spectrum, order normalized spectrum) and the same
resolution.
Setting Up Alarms, Lists,
and Inspection Codes This section describes the way Emonitor loads alarms, lists, and inspection
codes into the Enpac Ex. For more information on alarms, lists, and
inspection codes, see the Emonitor online help.
Alarms and the Data Collector
Emonitor and the Enpac Ex support loading alarms with the list of
measurement definitions to the data collector.
Selecting alarms to load to the Enpac Ex
• If you want to load an alarm to the data collector with a measurement
definition, you must set Trigger to "Yes" in the Alarm spreadsheet in
Emonitor.
• If you set Trigger to "Yes" for two or more alarms for the same
measurement definition, Emonitor combines them to make a single
alarm.
