Vibration testing is important for machine health monitoring and predictive maintenance. A vibration meter provides a simple way to screen machine health by measuring overall vibration (OV) and crest factor plus (CF+), which detects bearing damage. The meter compares readings to baseline values for 37 machine types. Users take measurements close to bearings and interpret severity levels on a four-level scale. Data can be stored in an Excel template to monitor machine condition over time. While a vibration meter provides basic screening, a tester is needed to diagnose faults and an analyzer for complex machines.
