5. The components and pipes inside the tower are made of 304 st*nless steel.
6. The device design allows for 360-degree observation, enabling all-round teaching and experimentation.
7. Three-purpose meter simulation software: This software is in apk format and can be used on PC or mobile terminals. The functions of this software are: measurement of resistance, measurement of AC voltage (measuring transformer, if the transformer measurement burns out) When the multimeter is broken, black smoke will appear and the multimeter can be reset), transistor polarity judgment, DC voltage measurement (the light turns on when the ammeter is turned on), DC current measurement, and 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. Demo and copyright certificate provided.
