Adash 4900 – Vibrio M

The instrument memory

The model A4900 - Vibrio M has a 4MB data memory.

Two instrument versions

You can buy two versions of this device. The basic, lower-priced version does not have memory. The
advanced version has a 4MB data memory. Both versions have the memory capability installed on
the board and only the firmware is different.

Upgrade to advanced version

If you want to upgrade the basic version to advanced version, ask your supplier. The firmware can
easily be rewritten to include memory without having to send your unit in.

Off-Route measurement

The instrument offers many kinds of measurement option. The results are displayed on specific
screens. Some screens contain more results (e.g. RMS and Peak), some screens contain only
one (e.g. spectrum). You can save each screen to the memory. Such data are labelled as OFF-
ROUTE.

Route measurements

A pre-defined list of required measurements can be prepare in the DDS2014 software on your
computer. Once the route is created, you load the list to the A4900 - Vibrio M instrument through a
USB connection. Then the standard route arrangement is available while in the field. You see the
name of sensor location on the screen (example Motor Outboard Horizontal -MOH), mount the sensor
to that point and take the measurement. Such data are labelled as ROUTE data. After data collection,
transfer the saved measurements back to your computer to further review the data within the software.
