1. Product Overview
With the rapid development of science and technology, process control equipment is becoming more and more automated, has more and more functions, and its operations are becoming more and more complex. Many smart instrument equipment are gradually being widely used. , therefore it is required that the skills mastered by on-site equipment m*ntenance and equipment personnel should also be constantly updated. This set of equipment can improve the theoretical technical level and practical operation skills of skilled workers and enhance workers' competitiveness under new conditions. This set of equipment can improve equipment m*ntenance, rep*r and operators' ability to handle problems on site.
2. System features
1. The object system is made of st*nless steel frame, and all components are designed with st*nless steel and aluminum alloy
. 2. The secondary measurement instrument of the sensor is installed on the object to facilitate students to perform various operations on site

9. Three-purpose meter simulation software: This software is in apk format and can be used on the PC or mobile terminals. Functions include: resistance measurement, AC voltage measurement (measuring the transformer, if the multimeter burns out when the transformer is measured, black smoke will appear and the multimeter can be reset), transistor polarity judgment, DC voltage measurement (when the ammeter is turned on) The light is bright), the measurement of DC current, and the judgment of 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, 1 station.
10. Teacher teaching design system: This system is in apk format and can be used on PC or mobile. This system can set faults manually or automatically. This system selects manual through the green box in the circuit diagram. Set fault points (up to 39 fault points can be set), or you can automatically set one fault point randomly through the system, set two fault points randomly, set three fault points randomly, set four fault points randomly, and set five fault points randomly. For fault point setting, this system has functions such as toolbox, component library, magnifying glass, circuit diagram, etc. You can select a multimeter for detection through the toolbox, select appropriate components through the component library, and clearly understand each component and circuit through the magnifying glass. This system 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. 1 Station
