THREE-DIMENSIONAL (3-D) BARCHART DISPLAY MODE
Vibration energy present at vehicle component frequencies is added together to represent
absolute vibration energy sampled. This data is presented in the form of a Barchart. The
most recent 11 cycles of data are stored on the screen with the most current cycle located
at the bottom of the screen.

NOTE
The Barchart display reflects the state of vibration energy that
is currently displayed on the 2-D display. The Amplitude range
on the 2-D display can be increased to eliminate frequencies
with low magnitudes. Only Spectral information present on the
2-D display is used to calculate the bars on the Barchart
display.
The Overlap Condition is indicated
by flashing arrows when the
condition exists.
The Out of Range condition is
indicated by a flashing “Hz” when
the condition exists.
