A-22 Standards Met HVM200 Manual
1. Under-Range (?) - The noise floor is below the measurement range of the analog to digital
converter.
2. The data in the above table was obtained by electrically testing the HVM200.
Whole Body - Wm, Wj, Wk
Notes:
1. Under-Range (?) - The noise floor is below the measurement range of the analog to digital
converter.

Type Precision
The Larson Davis HVM200 Human Vibration Meter is a Type 1 instrument designed for use in
assessing vibration as perceived by human beings. The instrument meets the requirements of ISO
8041:2005(E).HVM200
Additionally, the current ISO 8041:2005 standard, and therefore the HVM200 is compatible with the
standards listed below. These standards define methods for the measurement of whole-body and hand-
arm vibration.
• ISO 2631-1:1997 Mechanical vibration and shock -- Evaluation of human exposure to whole-
body vibration -- Part 1: General requirements
• ISO 2631-2:2003 Evaluation of human exposure to whole-body vibration -- Part 2: Continuous
and shock-induced vibrations in buildings (1 to 80 Hz)
