2.4 Test setup and results for LC-sensing design TIDA-01228

The precisely height-adjustable plate (with a 1um resolution) and a "off-the-shelve" stepper motor, controlled by DRV8846EVM by TI, build the rotation test setup for the LC-sensing solution. The GUI interface of DRV8846EVM allows for user-friendly control of the stepper motor’s turning speed to simulate minimum and maximum flow rates. High precision digital multi-meter resolves distances down to 1um and is used to adjust the distance between the mechanical plate, where TIDA-01228 is fixed, and the rotating disc, glued on a stepper motor.
