The X2-2 uses a high-sensitivity, low noise, 3-axis, +/-2g accelerometer sensor ideal for low amplitude vibration monitoring. Data is stored at user selectable rates up to 512Hz. The logger operates from an internal 500mAh lithium-polymer rechargeable battery that recharges when connected to a computer USB port. The X2-2 acts as a USB Mass storage device (like a USB flash drive) when connected to a computer, which provides quick and convenient access to data files. Data is stored as plain text Comma Separated Values format (.csv), ready to be imported into any spreadsheet, word processor, or end user application.

For more details, specifications, and how to use the X2-2, please refer to the user manual (.pdf). The user manual includes an example data file and instructions for converting the data and time stamps.
The X2-2 logger is configured using a simple text file called config.txt located on the microSD card. Below is an example:
; Example X2-2 Config file ; 2g range gain = low ; set to record constantly at 128Hz samplerate = 128 deadband = 0 ; set file length samplesperfile = 192000 ; LEDs on statusindicators = normal ; make device start upon USB disconnect rebootondisconnects
Data is stored to simple text formatted .csv type files, which are easily imported into any spreadsheet or analysis software (Matlab, Octave, R, etc). Below is a example data file:
