Algorithm

Evaluation

Prepare your setup:

• Calibration weight 100g
• usb connection to prototype
  • BLE?
• prototype flashed with readout_test
• weights: 0.1g, 0.5g, 1g, 5g, 10g, 50g, 100g, 500g, 1kg

uv run evaluation <description>

We evaluate

• Precision/Repeatability
• Accuracy wrt calibration weights
• Resolution (jittering)
• Resolution (range)
• Linearity
• Corner Loading
• Drift
• Environmetal impacts
  • temperature
  • huimidity
  • power source
  • vibration conditions
