Abstract

The present application discloses a method and device for testing an electromyograph, the method comprising: controlling a signal generator connected to the electromyograph to emit an initial electrical signal; gradually increasing the voltage peak of the electrical signal emitted by the signal generator according to a first predetermined step length; gradually increasing the frequency of the electrical signal emitted by the signal generator according to a second predetermined step length; obtaining the result of the electrical signal test obtained by the electromyograph each time the first predetermined step length and / or the second predetermined step length changes; comparing the result obtained from each test with the electrical signal emitted by the signal generator to determine whether the test is passed. The present application solves the problem caused by the lack of a solution for testing an electromyograph in the prior art, thereby providing data for objectively evaluating the performance of an electromyograph.
