The X16-4 is a rechargeable version of the X16-1D. The X16-4 uses a digital 3-axis 16g accelerometer, a 500mAh rechargeable lithium-polymer battery, and a convenient push button switch to start and stop data recording. Data is recorded at user selectable rates of up to 400Hz at 16-bit resolution. The X16-4 acts as a USB Mass storage device (like a USB flash drive) when connected to a personal computer. Data is stored as plain text Comma Separated Values (.csv), ready to be imported into any spreadsheet, word processor, or end user application.

For more details, specifications, and how to use the X16-4, 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 X16-4 logger is configured using a simple text file called config.txt located on the microSD card. Below is an example:
;Example X16-4 config file ;set sample rate ;available rates 12, 25, 50, 100, 200, 400 samplerate = 100 ;record constantly deadband = 0 deadbandtimeout = 0 ;set file size to 15 minutes of data samplesperfile = 90000 ;set status indicator brightness statusindicators = high ;rebootOnDisconnect ;see X16-4 user manual for other config options
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:
