The phase is a time delay expressed in degrees of rotation. Once measuring results are collected, an EVAM 'criterion' can be created that compares new parameter values with the statistical mean value and displays a dimensionless condition value against a green-yellow-red scale. In Condmaster, alarm limits can be set on all active parameters.

Suitable symptoms and symptom groups are selected from a menu in the Condmaster analysis and diagnostic software when the measuring point is set up. Most fault symptoms are automatically configured by using the rpm as a variable. These are instructions to highlight a spectrum line pattern and display the sum of the lines' RMS values as a symptom parameter (that can be evaluated and trended). Spectrum analysis with 'symptoms'ДЇor easy pattern recognition in spectra, EVAM supplies a range of ready-made 'fault symptoms'. Peak and peak-to-peak values are shown in the unit selected for the time signal. The noise level in the four quarters of the frequency range Skewness the asymmetry of the vibration signal Kurtosis the amount of transients in the vibration signal

Available condition parameters are: VELД¬rest value the difference between peak and RMS They can be individually activated and are shown in measuring result tables and as diagrams. Condition parametersД¬ondition parameters are measured for a selected frequency range. It is possible to distinguish between various faults that occur with the same pattern in an FFT spectrum. It shows the time between events and how much energy is generated from the event. It gives a reflection of all events happening in the machine. The time signal is the electrical signal coming from the transducer. The time signal is the source for all evaluation and calculation of frequencies from the machine.

Random high readings caused by resonance or other sources of disturbance are filtered out, minimizing the number of false alarms.

time signal analysis for a detailed evaluation of all kind of symptoms direct from the raw signal.

band alarms and averaging of measurement results for improved alarm reliability.

Machine specific condition codes (green, yellow, red) and condition values, based on a statistical evaluation of the condition parameters and fault symptom values.ДЇor each measuring point, the user can make an individual selection and define the type of data best suited for the surveillance of a particular machine.

Vibration spectra, where significant line patterns are found, highlighted, and evaluated with the help of preset fault symptoms.

Condition parameters, which are measured and calculated values describing various aspects of machine vibration.

The method generates three sets of machine condition data: EVAM stands for Evaluated Vibration Analysis Method.
