Collect Offroute Data using a Pre-defined Measurement
The Enpac 2500 data collector provides seven pre-defined measurements for you
to use to collect Offroute data. These are the data collectors pre-defined
measurements.
You do not set any parameters when you use a pre-defined measurement. The
Enpac 2500 data collector uses similar settings as the measurement definitions for
the current point.
Follow these steps to collect an Offroute measurement for the current point.
1. From the Main Menu, select Data Collection and press one of the Enter
keys.
The Data Collection screen appears.
2. Select the route and measurement point.
3. Press F2 (Offroute) to collect an Offroute measurement.
Table 35 - Pre-defined Measurements
Measurement Description
Same Uses the same setup as the current point.
Opposite Uses the opposite setup as the current point.
For example, spectrum is time, time is spectrum.
Accel Acceleration spectrum point
10kHZ, 800 lines, 4 averages
Velocity Accel velocity spectrum point
2kHz, 400 lines, 4 averages
Accel Time Time point
10kHz, 2046 points
High Res High resolution point (increase number of lines by a factor of two.
For example, the current point having 400 lines becomes 800 lines.
gSE Spike energy point
Envelope parameter in Instrument Setup must be set to gSE.
See
Instrument Configuration Parameters on page 44 .
ESP Standard Envelope Spectrum Processing (ESP) point
Envelope parameter in Instrument Setup must be set to ESP.
