1. M*ntenance of electricians, electronic motors and vocational qualification tr*ning assessment simulation software

This software is in apk format and can be used on PC or mobile. This software can set faults manually or automatically. This software can manually set fault points through the green box in the circuit diagram (you can set up to 39 fault points), you can also automatically set one random fault point, two random fault points, three random fault points, four random fault points, and five random fault points through the system. It has functions such as toolbox, component library, magnifying glass, circuit diagram, etc. You can choose a multimeter for testing through the toolbox, select appropriate components through the component library, and clearly understand each component and circuit through the magnifying glass. This software allows students to understand the working principle and circuit structure of the motor star-delta start control circuit through the setting of faults in the motor star-delta start control circuit and various investigations.

2. Virtual spectrum analyzer, logic analyzer, oscilloscope, and three-meter simulation software:

This software is in apk format and can be used on PC or mobile terminals. The functions of this software are: resistance measurement, AC voltage measurement (measuring transformer, if the multimeter burns out when measuring the transformer, black smoke will emit prompts and can reset the multimeter), determine the polarity of the transistor, measure the DC voltage (the light turns on when the ammeter is turned on), measure the DC current, and determine the quality of the capacitor. This software can drag the red and black pen tips at will. When the two pen tips are dragged and positioned on the object to be measured, a red circle will be displayed. If the positioning is not accurate, no red circle will be displayed, and when incorrect operations are performed (such as the wrong range selected, If the measured data is wrong, etc.), the meter pointer will be unresponsive, prompting errors and re-measurement, etc. This multimeter can select AC voltage range, DC voltage range, resistance range, current range, resistance adjustment to 0, and can enlarge the display data. Clearly view the measured data size. Students can learn the correct use of multimeters through this software.
