Chapter 4 Collecting and Reviewing Data
The Magnitude Measurement screen appears.
A graphic appears on the screen while the data collector ranges the data.
The data collector continually updates the magnitude value for the
measurement.
4. Once the magnitude reading is steady and the input signal is not
overloading the data collector, press Enter to accept the measured value.
Once the data collector stores the measurement, the Data Collection screen
displays the next point in the list (route).
Collect a Spectrum Measurement
One of the most useful ways to display vibration signals is in a spectrum. The
spectrum displays the vibration signal level in relation to the frequencies at which
the vibration occurs.
To display a spectrum, the Enpac 2500 data collector analyzes the frequency
components of the signal and breaks this analysis down to a number of frequency
bands where the signal level for that band is represented by a single value. These
bands are calstatus indicator lines.
IMPORTANT You do not need to press Enter if you set Auto Store to On in the
Instrument Configuration screen. The data collector automatically
ranges and collects the measurement.
See Instrument Configuration Parameters on page 44 .
