Measurand

 
1. Measurand
The connected sensor determines the measurand. Additionally, VM-TRACK+ can manage the integrated measurands. Therefore it offers vibration velocity and displacement when linked to an accelerometer.
The units are listed matching the measurand. The characteristic value should neither rise above 10 000 nor fall below 0.001 permanently. This should be noted while selecting a unit.

Characteristic

 
2. Characteristic
In Order analysis mode the following characteristics are available:
Peak value
The height of the order represents the amplitude of the corresponding sinusoidal signal.
True RMS value
The height of the order represents the true RMS value of the corresponding sinusoidal signal.
Peak-to-peak value
The height of the order represents the peak-to-peak amplitude of the corresponding sinusoidal signal.
 
In Overall value mode The following characteristics are available: Instantaneous value, Peak value absolute, Peak value positive, Peak value negative, Peak-to-peak value, True RMS value.
