Installing Optional Extension Modules
The data collector uses the Extension Manager to install and uninstall extension
modules. These extension modules are licensed and ordered separately from the
basic entry-level product.
Install Extension Modules
The installation Secure Digital (SD) cards that you receive work with any
Dynamix 2500 data collector. Once you have installed an extension module on
the data collector, the card is locked so that it can be used with only that
instrument.
You can uninstall extension modules, if required. When uninstalling an extension
module, you have the option to free up the license so you can install the extension
module on another data collector. This makes the extension module available to
be transferred between units.
Follow these instructions to install an extension module.
1. Open the base cover at the bottom of the Dynamix 2500 data collector.
2. Place the extension module Secure Digital (SD) card contact-side-up into
the unit until it is firmly seated in place.
3. Close the base cover.

IMPORTANT
One installation SD card is required for each instrument that needs to
be upgraded.
IMPORTANT
When ever you re-run the OS Loader software, you will re-load only the
main OS firmware. The OS loader will backup licence files and data, but
not the optional extension modules. Once you have updated the OS
firmware, install the latest version of your optional extension modules.
See the Dynamix 2500 Data Collector User Manual, 1441-UM001, for
more information.

Bump Test Extension Module
The Bump Test extension module is an optional module for the Dynamix 2500
data collector. You install the extension module with the Bump Test SD storage
card.
See Installing Optional Extension Modules on page 7 for installation
instructions.
The Bump Test extension module for the Dynamix 2500 data collector provides
an effective way of determining natural (or resonant) frequencies of a machine or
structure.
A bump test (or hammer test) determines the natural frequencies of a machine or
a structure. The idea behind the test is that when an object is impacted or
bumped, the object’s natural or resonant frequencies are excited. If a
measurement is taken while the object is vibrating due to the impact, peaks will
result and pinpoint the object’s natural frequencies. The Dynamix 2500 data
collector can be used to capture this frequency response and illustrates the
resonant frequencies.
Vibration forces transmitted by rotating machines often excite natural resonance
in structures attached to the machine. When these structural resonances appear,
vibration levels are amplified and can result in fatigue failures. Structural
resonances can also mask the cause of a machine’s vibration making it difficult to
implement corrective machine maintenance. The Bump Test identifies a
structure’s resonant modes and provides you with the opportunity to change the
resonance frequency to reduce or eliminate damaging vibration levels.
