Measurement shows within blind zone

Answer: The measured distance is shorter than the blind zone distance; the factory default blind zone is 0.3 m.

Solutions:

1. Adjust the sensor-to-target distance to ensure it exceeds the blind zone.

2. Reduce the blind zone distance (minimum 0.05 m); set a proper value based on actual conditions.

Configuration:

• Modify blind zone via upper computer AT command: AT+BLINDZONE=0.05.

• Modify blind zone via Bluetooth: App Parameter Configuration – Blind Zone Distance.

Minimum blind zone specifications by measuring range:

• 10 m range: Minimum blind zone 0.05 m

• 20 m range: Minimum blind zone 0.10 m

• 30 m range: Minimum blind zone 0.18 m

• 40 m range: Minimum blind zone 0.20 m
