Function: can carry out comprehensive tr*ning on the installation of fire hydrant system pipelines and equipment, and can carry out demonstration of fire hydrant system operation engineering.
Three-meter simulation software: This software is in apk format and can be used on PC or mobile. The functions of this software include: resistance measurement, AC voltage measurement (measuring transformer, if the transformer burns out when measuring the multimeter, black smoke will be emitted and the multimeter can be reset), transistor polarity judgment, DC voltage measurement (the light is on when the ammeter is turned on), DC current measurement, and judgment of capacitor quality. This software allows you to drag the red and black pen tips at will. When the two pen tips are dragged to the measured object for positioning, a red circle will be displayed. If the positioning is not accurate, no red circle will be displayed. When an incorrect operation is performed (such as the selected range is wrong, the measured data is wrong, etc.), the instrument pointer will not respond, prompting an error to re-measure, etc. This multimeter can select AC voltage, DC voltage, resistance, current, resistance adjustment 0, and can enlarge the displayed data, so that the measured data size can be clearly viewed. Students can learn the correct use of the multimeter through this software. Demonstration and copyright certificate are provided. Virtual simulation software for electrical installation of
building buildings and intelligent buildings Based on unity3d design, users can choose different sizes of interactive interfaces according to computer configuration, and can choose six levels of image quality.
