- Ensure any plastic insulation tab has been removed from the batteries.
- Replace with fresh AAA batteries.
- Inaccurate readings:
- Ensure the unit is placed in a location away from direct sunlight, heat sources, or drafts, which can affect accuracy.
- Allow the unit to stabilize for at least 30 minutes after initial setup or relocation.
- Compare readings with another calibrated thermometer/hygrometer if available to confirm significant discrepancies.
