Chapter 6 Multi-channel Measurements
Two-channel Measurements The Emonitor software and the Enpac 2500 support two channel measurements
definitions.
Set Up Two-channel Measurement Definitions in the Emonitor
Software
Follow these steps to set up a two-channel measurement.
1. Set up a location in the Location pane for the two input channels.
The Location Ids must be different. Set Lo. Channel for the first location
to 1. And set Lo. Channel for the second location to 2.
The measurement definitions must be the same for both locations.
2. Assign the same group number to the locations to collect the
measurements properly.
Follow these steps to set up the two-channel measurements in the Emonitor
software.
1. Select the machine in the Hierarchy Tree for which you want to set up the
dual channel measurements.
2. In the Location pane, create the first location and set Lo. Channel to 1.
3. In the Measurement Definition pane, create the measurement definition.
4. In the Location pane, select the new location that you just created. Choose
Edit > Copy to copy the location.
5. Move to an empty row in the Location pane and choose Edit > Paste to
paste the new location into the spreadsheet.
6. Edit the new location. Make sure you set Lo. Channel to 2.
7. Include these locations in a list. You can create a new list or recall the
current list. The locations must be tagged to create a group list.
8. Add the two 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 the same group number. The group is then loaded with
the list to the Enpac 2500.
IMPORTANT Make sure the measurement definitions are not similar to either the orbit
measurement definitions or the cross channel phase measurement
definitions. You may get unexpected results.
