Chapter 3 Setting Up Measurements

Measurement Maximum Frequencies

The measurement maximum frequency is part of the collection specification

(Setup > Collection). See Collection Specification Dialog Box on page 75

Select the collection specification when you set up the measurement definition.

The Emonitor software and the Dynamix 2500 data collector support the

following maximum frequencies in Hz (CPM).

Peak Use for detection of acceleration, velocity, and high frequency energy. This is the

peak (0 to maximum) amplitude of a sine wave at the frequency of interest and is

calculated from the RMS value.

True Peak Use to detect impacts and random transients. The dynamic time signal contains

the absolute value of the largest peak (positive or negative) within a specified

time window. Returns a magnitude value only. If used with a spectrum

measurement, the Emonitor software uses a Peak signal detection type instead.

This value is not calculated but is measured directly.

True Peak-Peak Use to detect impacts and random transients. The dynamic time signal contains

the absolute value of the largest peak to peak distance within a specified time

window. Returns a magnitude value only. If used with a spectrum measurement,

the Emonitor software uses a Peak-Peak signal detection type instead. This value

is not calculated but is measured directly.
