Modes

What is a Mode?

A mode is a group of measurements that share similar characteristics — particularly in how their spectra look in terms of peaks and energy distribution. Instead of reviewing hundreds of individual measurements, you can inspect one representative example per mode and understand the machine’s behavior in seconds. In a typical case, 780 measurements collapse into just 4 modes.

Modes are identified automatically and shown as different background colors in the trend plot of the Deep Analysis View, making behavior transitions easy to spot over time.

Events within modes

Modes are not static. When a mode’s energy shifts — for example increasing in the higher or lower part of the spectrum — MultiViz flags this with an event that shows exactly where in the frequency spectrum the shift happened. These events are what drive a source’s priority.

Off modes and anomalies

• Off modes (gray) mark the absence of modes — typically when the machine is inactive or sensors are not sending data. You can hide them with the “Off Measurements” toggle.
• Anomalies (white) are measurements that do not match any known mode — potentially pointing to something new and worth investigating.

Why modes matter

Modes let you skip the noise: instead of fixed thresholds that fire on every fluctuation, MultiViz learns each machine’s normal behavior patterns and alerts you only when something meaningfully shifts. That means fewer false alarms and faster decisions.
