Abstract During the implementation of the project "Deep Exploration Technology and Experimentation (SinoProbe)" in China, the MT instruments MTU-5,V8 and LEMI-417 were used. However, their human-machine interface was based on character, which made it difficult to find useful information and faulty operation during data acquisition. The oscilloscope can display the law of the time-varying electrical signals that can not be captured by visual sense, so the technology is used in the CLP, a magnetotelluric instrument designed by an exploration party, which means its human-machine interface is based on graphics. The GUI is developed with Visual C++ 6.0. Firstly, the display area of the screen is defined. Secondly, the objects of the class CDC (Device Context), CPen, and CBitmap are set up, and the virtual oscilloscope is designed with them. Then the collected data are displayed through graphics. Furthermore, the virtual oscilloscope can be adjusted automatically according to the monitor property. The experiments show that this display method can help the operator analyze the collected data and provide guidance for the next step.
