Chapter 6 Multi-channel Measurements
The measurement definitions must be the same for both locations. The
time measurement definition must be the first measurement definition in
the spreadsheet. Make sure the numeric measurement definition has the
same units, collection specification, and storage as the time measurement
definition.
• Make sure to set Data collector filter type to Analog when you define the
order filters.
See Measurement Filters on page 67
for more information.
• Assign the same group number to the locations to collect the measurement
properly.
To set up the orbit measurements in the Emonitor software, follow these steps.
1. Select the machine in the Hierarchy Tree for which you want to set up
orbit measurements.
2. In the Location pane, create the first location and set Lo. Channel to 1.
3. In the Measurement definition pane, create the time measurement
definition by setting Data Type to Time.
4. Set Collection to the collection specification that you created for the orbit
measurement.
5. Select the appropriate order Filter.
6. Select the measurement definition that you just created.
7. Choose Edit > Copy to copy the time measurement definition.
8. Move to an empty row in the Measurement Definition pane and choose
Edit > Paste to paste the new measurement definition into the spreadsheet.
9. Edit the new measurement definition. Change Data Type to Numeric and
the Filter to None.
10. In the Location pane, select the location that you just created.
11. Choose Edit > Copy to copy the location.
If the Lo. Channel is not in the Location pane, choose
View > Pane Options to add the column.
Press F1 in the Pane Options dialog box for assistance.
An Order-based filter may be used for isolating
mechanical defects related to operational running
speed. However, in order to see all potential defects,
non-harmonic related, an Overall filter must be applied.
