CHAPTER
1Introduction
Thank you for purchasing the Human Vibration Meter from
Larson Davis. The HVM100 is a powerful but small vibra-
tion measurement tool. This Handheld vibration analyzer
will allow a variety of applications to be performed includ-
ing; Whole Body Vibration analysis, Hand-Arm Vibration
analysis, and general purpose vibration analysis.
This full featured vibration analyzer features 3 input
channels, a sum channel, a variety of frequency weighting
and band limiting settings, single and double integration,
displayed data in a variety of units, and independent AC or
DC outputs for all 3 channels simultaneously.
We invite you to read this manual to obtain the best results
from your HVM100.
About This Manual
This manual has 9 chapters and 5 appendices covering the
following topics:
Chapter 1 - Introduction
In this chapter we will discuss the functionality and
capabilities of your HVM100. We will also go into detail
with regards to frequency weightings and screen and menu
functionality.
Chapter 2 - Getting Started
This chapter will describe in detail the functionality and
selections contained in the Setup menu.
Chapter 3 - The Tools Menu
This chapter will describe in detail the functionality and
selections contained in the Tools menu.
