摘要：
The utility model relates to medical equipment, namely, an electrocardiographic technique for recording the biopotentials of the heart on the surface of a person’s body, and is intended to provide testing of electrocardiographs in test centers, laboratories and "on the spot". The technical result of the proposed technical solution is to increase the ergonomics of the device with its autonomous (outside the computerized stand) application. This technical result is achieved due to the fact that in the well-known simulator for testing electrocardiographs containing a USB 2.0 interface for communication with a personal computer, a memory unit and a display associated with a microcontroller, one of the outputs of which is connected to the sound indication unit, and the other to the first input An 8-channel digital-to-analog converter (DAC), as well as a stabilized reference voltage generating unit, the output of which is connected to the second input of the 8-channel DAC, each of which outputs is connected to One of the corresponding channels of the 8-channel low-pass filter (LPF), 1 and 2 automatic switches are introduced, as well as a high-pass filter (HPF), while the eight outputs of the 8-channel low-pass filter are device outputs designed to connect eight signal electrodes L, F , C1 - C6, respectively, the input 1 of the automatic switch is connected to the output of the 1-channel DAC, the first output 1 of the automatic switch through 1 scaling amplifier is connected to the input 2 of the automatic switch, the first output of which is connected with analog ground, and the second output is the output of the device, designed to connect the reference R electrode. In this case, the second output 1 of the automatic switch through a scaling amplifier and a high-pass filter connected in series 2 is connected to the Sign-Out output used in common-mode signal suppression tests, and the device output intended for connecting the N electrode is connected to analog ground. 3 il
