GE SCOUT140-Ex - Setting Y Axis (Amplitude) Scale

Section 7 — Analyzing Measurements Onsite

Set Y Axis (Amplitude) Scale
You can toggle the left axis scale between Linear, Log, and dB to
increase or decrease the amplitude of the peaks displayed. This enables
you to see the bigger picture or access a more detailed view of your
data. The Linear scale is suitable for most cases. Log scaling (base 10) is
more useful for displaying vibration for very large or very small
amplitudes.
To access the required option:
1. Display the spectrum measurement on your screen.
2. Highlight your spectrum measurement.
3. Press > Press Y Axis Log to set the Y axis (amplitude)
scaling options.
4. Press Linear Log dB repeatedly to toggle between Linear, Log,
and dB scaling.
NOTE: VdB and adB scaling are only available when you measure
velocity and acceleration respectively.
5. Press Y Axis Max — This is the highest amplitude value that will
be displayed on your screen.
6. Use the arrow keys to highlight a value > Press to select the
value.
7. Press Y Axis Range repeatedly to toggle the Y Axis range —
This selects the lowest amplitude value that will be displayed on
your screen, relative to your chosen Max value.
8. Press when you have finished to return to the measurement
screen.
