- Validate that the power supply and PCB consistently deliver accurate, stable voltages across all circuits and connections, confirming operational reliability
- Thoroughly inspect the display for any dim, flickering, or dead pixels, replacing compromised segments to ensure clear visibility and precise data display
- Verify complete functionality and responsiveness of all buttons and knobs, confirming accurate and reliable input across all controls
- Ensure the machine completes all internal diagnostic checks with zero errors, indicating system readiness and functional integrity
- Confirm the machine accurately identifies attached blocks (96-well, dual 48, etc.), with seamless recognition across different configurations
- Conduct a detailed inspection of internal wiring and all electrical connections, checking for any signs of breaks, disconnections, or tears; replace or repair any underperforming components
- Examine the connector between the block and base for bent or broken pins, replacing as needed to maintain secure, reliable connections
- Calibrate well temperatures with a NIST-traceable thermometer, verifying accuracy and uniformity across all wells to meet specification standards
- Perform a comprehensive cosmetic inspection, ensuring all exterior surfaces and components are free of damage, wear, or defects, maintaining aesthetic and professional quality
