1. Purpose
Thank you for choosing a vibration meter from Metra!
The VM30-H was developed for the measurement of human vibrations. In addition, it is suited
for many other fields of vibration measurement such as machine vibration, building vibration or
quality control.
The instrument can measure triaxial hand-arm vibration to EU directive 2002/44/EC based on
ISO 5349 and whole-body vibration to ISO 2631. It conforms to the latest edition of ISO 8041
for measuring instrumentation for human vibration.
Particular attention has been paid to simple operation, compact design and long battery
operating time.
