Page 6: Why A4900 - Vibrio M
You should not equate our unit with "vibration pens". The Adash model A4900 is a multi-function portable meter and data-collector that bridges the gap between the basic and advanced FFT data-collector/analyser. It is a complete machine condition expert system than gives results without the use of a computer or lap top. -

Such data are labelled as ROUTE data. You download them back to the computer and use the software for next data acquisition. Further technical and contact information can be found at www.adash.com... -
Page 8: Vibration Diagnostics - Basic Information
The way how to find the good condition values is to use measured values of new or repaired machine. Also you can ask the machine producer for them. 5. Shortening of an interval between measurements means more successful prevention of unexpected failures. Further technical and contact information can be found at www.adash.com... -

Page 12: Listening To Vibrations Using Headphones
In the end put the cover on the pad. Listening to Vibrations Using Headphones A user can connect headphones to the Adash 4900 – Vibrio M instrument, since listening to a measurement signal also enables a differentiation of a problem type. People can think that this is an old method, which does not have a place in this modern world. -

Page 15: Standards For Vibration Measurements
The standards should be rather determined for a narrow range of machines. A4900 - Vibrio M contains Adash limit values and ISO 10816 limit values. Adash limits are not rewritten from any existing standard. It’s a result of 20 years of Adash engineering team experiences. -
