Chapter 2 Setting Up Measurements
Setting Up Tri-axial Measurements
You can set up and collect tri-axial measurements with the Enpac 2500 if you
have a tri-axial transducer and a special tri-axial cable for your Enpac. This allows
you to collect measurements in three directions without moving the transducer.
Tri-axial measurements require setting up separate locations, and measurement
definitions for each of the three transducers. This section shows the method for
setting up these measurements.
To Set Up Tri-axial Locations and Measurement Definitions
You must set up a different location for each axis of a tri-axial transducer.
The tri-axial data is multiplexed one direction at a time.
1. Open the Database window by choosing Window > Database.
2. Select the Measurement view and click OK.
3. Select the machine in the Hierarchy Tree for which you want to set up tri-
axial measurements.
4. In the Location pane, choose View > Pane Options to add the Lo. Channel
column to the Location pane. Press F1 in the Pane Options dialog for
assistance.
5. Create a Location for the first tri-axial measurement and set Lo. Channel
to ‘1X.’
6. In the Measurement Definition pane, create the measurement definition
for that location.
7. Select the location you just created. Choose Edit > Copy to copy the
location.
8. Move to an empty row in the Location pane and choose Edit > Paste to
paste the location into the spreadsheet.
9. Edit the new location to change the Direction and set Lo. Channel to ‘1Y.’
10. Repeat steps 7 and 8 to copy and paste the third location into the Location
pane. Edit the new location to change the Direction and set Lo. Channel
to ‘1Z.’
11. Now include these measurement definitions in a list. You can create a new
list or recall the current list.
The locations must be tagged in order to create a group list.
12. Add the three locations to a group list by double-clicking the Group
column in the Location pane. The current group number appears in the
Group column. Make sure you assign the locations to the same group
number. The group is then loaded with the list to the Enpac 2500.
TIP The Location ID and Position must be the same for all three tri-axial
measurements.
