Setting Up Measurements Chapter 3
You also need to select the window, frequency range, and averaging
options.
3. Finish setting up the dynamic proximity probe measurement by setting
Data Type to Magnitude and Units to mils or um.
You can use a Filter if desired, but make sure it does not interfere with the
frequency of interest.
Spectrum Alarms in the Dynamic 2500 Data Collector
The Dynamix 2500 data collector supports band alarms with up to ten bands.
You can have the data collector collect a spectrum measurement if a magnitude
alarm is in alarm.
1. Set the Collect and store condition in the Edit Storage Specification dialog
box to On Magnitude Alarm for the storage specification for the spectrum
measurement definition.
2. You must set Trigger to Yes for any alarms you want to appear in the
Dynamix 2500 data collector during data collection.
If you set Trigger to Yes for two or more alarms for the same measurement
definition, the Emonitor software combines the alarms before sending the
combined alarm to the Dynamix 2500 data collector.
For more on how the Emonitor software combines alarms before sending them to
the Dynamix 2500 data collector, see
Alarms and the Data Collector on
page 104 .
Typical Spectrum Measurement Definitions
This figure shows the setup for typical spectrum measurement definitions. The
first is a standard spectrum, the second is an order normalized spectrum, and the
third is a time synchronous spectrum.
Figure 19 - Spectrum measurement definitions
IMPORTANT The Dynamix does not support spectrum alarms. You can still set up the
alarms for the spectrum measurement definitions. the Emonitor software
tests the data against the alarms after you unload the data.
