• measuring small components or when the object is very close or very far. Always fine-tune the focus just before taking a measurement on a critical spot.

Summary of Optimization Steps

1. Set Emissivity (ε): Match the surface material value.
2. Set Background Temperature: Apply reflectivity compensation if necessary.
3. Select Palette: Use Iron or Rainbow for discovery; switch to Gray Scale for documentation.
4. Adjust Span: Narrow the span around your expected temperature range for maximum contrast.
5. Ensure Sharp Focus: Manually adjust if automatic focus fails or when inspecting small targets.

By mastering these settings, you transition from simply seeing heat to quantitatively analyzing thermal performance
