Tips: Operating instructions of ultrasonic sensor distance meter

1. Pay attention to the positive and negative poles when installing the battery, and only use alkaline batteries.
2. Do not aim the ultrasonic sensor directly at the sun, eyes or illuminate the eyes through a reflective surface (such as mirror reflection) during measurement.
3. The ultrasonic sensor distance meter must be handled with care during use, and should be avoided in places that are too humid, under high temperature or direct sunlight.
4. There will be large errors in the measurement results when the sun is too strong, the ambient temperature fluctuates too much, the reflection effect of the reflecting surface is weak, and the battery power is insufficient. In this case, it is better to use the target reflector.
5. When the ultrasonic sensor distance meter is not in use for a long time, please take out the battery and put the rangefinder in the instrument case provided, and store the distance meter in a cool place.
6. Please keep the surface of the distance measuring tool clean. You can wipe the surface dust with a damp soft cloth. Do not use aggressive liquids to clean the meter. You can wipe the ultrasonic window and focusing lens in accordance with the method of wiping the optical device table.
