6.7 Common data collection parameters
This section describes parameters that are available in most of the Analysis Experts and
Manual Analyze. To view these options, open Manual Analyze for a measurement.
6.7.1 Fmax and Fmin
The Fmax and Fmin values set the maximum and minimum frequency limits for your
measurements. Equipment with high operating speeds requires a higher Fmax to capture
all crucial information. The Fmin (low cutoff) removes very low frequency integration noise
from the overall measurement and is normally set at 2 Hz. You can set Fmin to 0, but the
minimum value is the second line in the spectrum, where the Fmin value is equal to 2x line
resolution.
Measurement Recommended setting
Fingered elements such as gear teeth, fan
blades, pump vanes, and bearing elements
(3 x the number of fingers) x the operating
speed
Non-fingered elements 10 x the operating speed
Coast up, coast down recordings 200 to 400 Hz (12,000-24,000 cpm)
