PCE Instruments PCE-VM 22 Vibration Analyzer User Manual

Do not place sensor on the objects which exposed to high voltages.
These voltages could cause personal injury or death.
The Analyzer could not be used in potentially explosive environments.

Take measures to prevent cables and straps become entangled by rotating part of machines at measurement site.
Do not expose PCE-VM 22 parts to heavy impacts, high humidity and extreme temperature.

Do not try to open the display unit – this can damage the system, and your after-sales service warranty will come void.

Overview

The PCE-VM 22 Vibration Analyzer (Device, Analyzer) is a compact yet powerful, vibration analyzer designed to measure overall vibration parameters, FFT spectrum analysis of the rotating machinery, immediate evaluation against ISO 10816 standard, condition monitoring by route based measurements and data collection.
Route files and data files exchange via email makes it ideal for data collection at remote sites. Simple in use, with free firmware upgrades, comes with data management and reporting software.

Vibration

Analyzer measures vibration Acceleration, Velocity and Displacement.
In ISO 10816 mode measurement result is compared to the built-in table of vibration severity grades according to ISO 10816-3.

Use keys to choose measurement mode.

Vibration measurement settings

Press key to enter Settings menu.
Use to choose parameter to setup.

Use to change parameter value.
Low Freq: lower frequency limit. Can be set to 1, 2, 10 Hz.
Hi Freq: upper frequency limit. Can be set:
- from 200 to 10000 Hz for Acceleration;
- from 200 to 5000 Hz for Velocity;
- from 200 to 800 Hz for Displacement;

FFT lines: FFT spectrum resolution. Can be set to 400, 800, 1600 lines.
Trigger: not implemented yet..
Averaging: measurement averaging. Can be set in range of 0 to 64.
Zero means that averaging is OFF.

Window: weighting function. Can be set to Henning or Rectangular.

Taking Measurements
