Display and Analysis of the EMG Data

The new Biometrics Analysis software comes with a comprehensive Help menu that may be used as a tutorial to use both the hardware and software for the first time.

The new Biometrics Analysis software is one of the most powerful yet cost effective EMG display and analysis software tools available. The software is purposefully NOT sold in modules but as one complete package to give the user a complete product at a price that is below most basic entry packages of other commercial products.

This is truly a cost effective high quality display and analysis software package offering the user exceptional value for money and ease of use.

EMG data collected with no filtering applied.)

Summary of Main Features

As soon as a file is opened it is displayed as a raw EMG file and may then be subject to any or all of the features listed above. The data may be left as a whole or truncated into smaller files of specific data for further analysis. Of course not only EMG data may be displayed at any one time. The Y axis may be labelled with any units governed by what sensors where connected at the time of recording, e.g. Kg or lbs for force or degrees for limb movement. These units are then saved with the file and automatically compute every time the file is reopened.

The digital inputs are displayed on a separate graph to the analog inputs. Using this facility toe contact and heel off may be obtained using the contact switch assembly type no. FS4.
