Polar Displays
Polar Displays show vibration amplitude and phase lag on a polar plot format. The data is corrected for probe
location. Phase lag is opposite the direction of rotation. You can optionally display the “Runout” compensated
values by clicking the associated button (see figure). The compensation values are specified for each channel in the
setup configuration.
Runout Compensation is a vector math operation, in which the referenced first order amplitude and phase vector is
subtracted from the displayed first order vector.
Note: Only one channel can be shown on a Polar Display.
