5. Set the following options as necessary.
Option Description
F2 Set Overall
Mode
Set your Overall acquisition to 1Hz to 80kHz or Fmin to Fmax. 1Hz to 80kHz
mode acquires broadband waveform data, and calculates the overall as
the RMS value of the waveform. Fmin to Fmax calculates the overall value
from a normal spectral acquisition and includes frequencies between the
Fmax and Fmin values. The default is Fmin to Fmax.
F3 Set Spectra
Params
Set the Fmax, Fmin, number of averages, and enable or disable Aweighting.
The default is 2,000 Hz Fmax, 0 Hz Fmin, and four averages.
F4 Set Number
Points
Enter a number between 2 and 6,400 to set the number of points to
collect. The default is 2,000.
F5 Set Time Inc Enter a number between 0 and 60 seconds to set the time between each
measurement. The default is 1.
F7 Tach Setup Set up the tachometer parameters. See Section 6.6.1.
F8 Set Collection
Mode
Overall acquisition can be Continuous or Non-Continuous. Continuous mode
collects the required number of points and continues collecting data,
replacing the oldest data with new data. Non-Continuous mode only
collects the required number of points and then stops collecting data.
The default is Continuous.
F9 Set Alarm Level Set an alarm level for the measurement. If the measurement exceeds the
specified alarm level, the analyzer beeps until the acquisition stops or the
signal drops back below the alarm level. Enter 0 to disable the alarm. For
Dual Overall, set an alarm for all inputs. By default, this option is disabled.
F11 Set Time Span Set the displayed time span of the trend plot. The minimum value and
default is 10 seconds.
F12 Input Setup Set up the input channels, the sensor type, and the units for the
acquisition type.
6. Press Enter to collect the data.
One or more plots display the data.
7.
Press F9 Store Data to save the data to a route or a job, or press F8 Start to redo the
measurement.
6.9.4 Collect True Zoom data
True Zoom lets you zoom in on a specific piece of data and collect a high resolution 800-line
spectral plot over a narrow frequency band. True Zoom is similar to a zoom lens on a
camera.
Procedure
1. Create a job or open Analyze from a route measurement point.
2. From the Analyze main menu, press F1 Manual Analyze > F1 Set Analyze Mode.
3. Use the up and down arrow keys to select True Zoom.
