Multimeter 12 channel

thingiverse

Human-designed, high-precision 3D printed multimeter with a remarkable nine analog channels, spanning an impressive voltage range of -330V to 330V. Additionally, three current channels provide versatile measurement capabilities. Required components: The project necessitates a high-quality 7-inch screen TFT display, specifically the SSD1963 model. An Arduino Due board is also essential for processing and control. To power the multimeter, two protected LiPo batteries with a capacity of 3.7V are needed. Alternatively, a battery box or the provided baterie_pojemnik.STL design can be used. Key electronic components include: - Nine high-value 2-megohm resistors - Thirty-three 10-kilohm resistors for precise voltage measurements - Three 68-ohm resistors for added functionality - Nine 10-nanofarad capacitors to filter frequencies above 1 kilohertz A prototype board with dimensions of 33 by 178 millimeters is also required.
