The DataLOG (MWX8) is developed to meet the needs of researchers for portable data collection and monitoring in human performance, sports science, medical research, industrial ergonomics, gait laboratories, and educational settings.
DataLOG can be worn on the arm or leg in addition to the traditional belt/waist placement and incorporates a color graphics LCD, joystick, micro SD card interface, and a real-time Bluetooth® wireless technology link to a PC.
During all stages of the design and development process, attention has been given to the Bluetooth Wireless link, providing real-time data transfer and display. In addition, the data is automatically backed up to the Micro SD card providing complete peace of mind.
|Dimensions||104 x 62 x 22 mm|
|Battery Type||2 x Alkaline AA
(see here for recommendations)
The following batteries are recommended:
We do not recommend the use of any rechargeable cell technology. Do not use as this will cause problems with auto power down and stability of recording to card.
|Battery Life||5-20 hours nominal depending on sensor type and quantity
(see here for guidance)
The maximum length of a recording will be influenced by the batteries as follows:
The following is given for guidance only:
|Microprocessor controlled programmable gain amplifiers|
|Number of Goniometer Channels||0 to 8, dependent on number of general analog channels (user select)|
|Number of General Analog Channels||0 to 8, dependent on number of goniometer channels (user select)|
|General analog channels may be single ended or differential dependent on front end plug wiring configuration|
|Memory Internal||2GB Micro SD card|
|Bluetooth Adaptor||Microsoft Bluetooth stack compatible|
|Front End ADC||14 bit giving +/- 4000 counts resolution|
