If you define two measurement points, 90 degrees apart, for each measurement plane,
you can see if both axes react similarly. Occasionally, equipment does not react
symmetrically due to a significant difference in constraint between axes or resonance.
Note
You can define up to three sensors for each measurement plane. No more than one sensor can be
axial (to measure vibration parallel to the shaft), but you can define all three as radial to measure
vibration perpendicular to the shaft.
Compare the display to the equipment to verify your setup information is correct. The
sensor positions are important to the accuracy of the Watchdog data checks that the
analyzer performs after you acquire the reference run data. The Estimate Trial Weights and
system lag calculations in Calculator Mode may also be affected. The parameters ensure the
analyzer displays the desired units. When auxiliary calculations are made for trial weight
placement, know the correct magnitude units.
9.4.2 Effect of incorrect sensor units
Whenever possible, use the same sensor units for all measurements. If you select the
wrong sensor units, you can complete the job using those same units. The analyzer
correctly calculates the influence coefficients for the correction weights, if you do not
change the original units. They are simply in a different measurement unit.
If you need to change units, you must repeat all readings. The analyzer cannot convert the
units. After the job is complete, take a final set of readings in the desired units or manually
make the correct conversion to know how the magnitudes compare to your specifications.
In Advanced Balance mode, use Units Conversion in Calculator Mode to calculate the units in
acceleration, velocity, and displacement.
9.4.3 Set up a sensor
Note
You can define only one sensor type for a job. If you change the sensor type for any measurement
plane, the sensor type changes for all measurement planes.
Procedure
1.
From the Balance main menu, press F3 Job Setup.
2. In Basic Balance mode, press F12 Sensor Setup. In Advanced Balance mode, press Enter
> F6 Sensor Setup.
3. Set the following options as necessary.
Option Description
F2 Sensor Type Select the sensor type. The analyzer uses the same sensor type on all
measurement points. The default is an accelerometer.
