The digital medical accelerometer 1D402HA is designed for non -invasive vibro -acoustic screening of the vessels of the heart. The sensor works in the HeartBeat Administrator software environment. This program provides the following opportunities for the functioning of the accelerometer: Study of the heartbeat; Research of intracranial pressure; installation of the mode of operation of the sensor; launching and stopping vibration measurements; assignment of corrective coefficients; reading the measured vibration data, their graphic display and calculation of special parameters; recording (reading) of measured vibration data to a file (from a file); Reading WAV audio files recorded by medical monitoring equipment.
