Introduction

The MTN/VM220 Vibration Meter is a rechargeable, portable instrument designed to operate with a constant current

type accelerometer to provide accurate vibration measurements.
Conforming to ISO10816-3/7, MTN/VM220 will display RMS, peak, peak-peak, crest factor and bearing condition on its
colour screen. Up to 100 time-stamped readings can be stored to non-volatile memory.

The MTN/VM220 is an invaluable trouble-shooting tool for instrumentation engineers familiar with the problems of
plant vibration monitoring, providing an instant readout of the condition of bearings and rotating parts.

Connections

The headphone jack

will accept a 3.5mm stereo jack plug. Headphones (not included) may be used to listen to the vibration

directly.

To avoid hearing damage, use of headphones with an inline volume adjustment is recommended. Ensure the volume is turned
down before connectin

g your headphones. After placing headphones in your ears, gradually turn up the volume until you reach a

comfortable listening level. Do not use headphones when it's unsafe to do so - while operating a vehicle, or during any activity or in
an environment where your full attention to your surroundings is required.
