When you shut down the equipment after acquiring the reference run data, watch the
vibration and phase. Record the data if possible. Use the data to determine the presence of
a resonance near or below running speed.
View measurement data with or without runout
From the Select Measurement Point screen, press F4 or F10 Toggle Runout.
Each time your press F4 or F10, the option changes. When runout is selected, "with Runout
Compensation" displays.
Acquire reference run (as-is) data
In Advanced Balance Mode, the analyzer acquires additional data for the Balancing
Watchdog data checks, so you may notice a slight increase in the time to collect data.
CAUTION!
Follow proper safety and equipment lock out procedures when working around rotating
equipment. Acquire data from the specified location for the highlighted measurement point. If
you assign data from other measurement points to this location, you invalidate all calculations.
Prerequisites
Complete or review the Job Setup option.
Attach one or more vibration sensors and the tachometer to the analyzer.
Ensure the machine is running.
If you use more than one sensor and do not use the CSI 2140 Four-Channel Input
Adapter, ensure you connected the proper cables before collecting data. Collect the
measurement for the appropriate input.
Procedure
1.
From the Balance main menu, press F4 Acquire Data > F2 Acquire Ref. Run Data.
2. Place the sensor at the measurement point location.
3. If you set up multiple speeds, press the key for the corresponding speed.
4. Use the up and down arrow keys to select the measurement point.
5. Press Start Data Acq. to collect data for the selected measurement point.
The Acquire Data screen appears. Collect data until the magnitude is stable and
phase varies by no more than 5 degrees in the Data Stability graph.
6. Press Accept Data.
If you selected Auto for the mux option, the Balance program automatically accepts
the data and moves to the next point when the phase and magnitude are good for 3
consecutive averages. See Section 9.4.5.
