Glossary
active data collector
You can define one or more data collectors as active. Emonitor uses the active
collectors to determine the valid options when you set up measurement
definitions. Suppose you had two active data collectors:
DC1 can measure velocity in both in/sec and mm/sec
DC2 can measure velocity only in in/sec
The only choice you would see for velocity units would be in/sec, because that
is common to both active collectors. This is true for several options in
Emonitor, including the number and length of inspection codes.
active list
The list for which you are currently collecting data. You can load multiple lists
into the EnpacEx. You can only collect data for one list at a time.
alarms
An alarm alerts you to a change in a measurement. For example, an alarm can
notify you when the measured value for a machine exceeds a pre-defined value.
You can create one or more alarms for each measurement definition.
archive data
The measurement data that you store in Emonitor. It includes all the
magnitude, process, time, and spectral data that you have collected and
unloaded or entered into the program.
averaging
Refers to the process of combining multiple data samples to reduce the
random errors and provide a more reliable measurement.
band
A frequency range, such as the frequency range between 1,800 and 3,200 Hz.
A band set consists of one or more bands. You can use bands to define specific
frequency ranges and values used - band maximum amplitude or band sum -
for a band alarm.
TIP
Aa
The active data collector is from the current data collector.
