- Validate that the power supply and PCB deliver stable, correct voltage outputs across all necessary connections, ensuring reliable operation
- Thoroughly inspect the display for any dim, flickering, or dead pixels; replace affected elements to maintain full readability and operational clarity
- Test the full range of button functionality, confirming responsive, accurate input recognition across all settings
- Conduct a detailed inspection of bearings and bearing housing, identifying any worn or damaged bearings, and replace as needed to prevent operational disruption
- Examine the drive belt for signs of cracking, fraying, or material breakdown; replace as required to ensure sustained performance
- Measure and adjust motor drive belt tension to optimal specifications, securing reliable and efficient power transmission
- Verify accuracy of the onboard timer, confirming proper functionality and replacing if it deviates from expected performance
- Calibrate shaker rotation speed with a NIST-traceable tachometer, validating precision within specified operational limits
- Run the shaker continuously for an 8-12 hour testing period, closely observing the shaking platform for smooth, consistent motion, while monitoring for any error indicators such as knocking, skipping, or unusual vibrations
- Perform a comprehensive cosmetic inspection to confirm the device’s exterior meets aesthetic and quality standards, free from visible damage or wear
