• Vertical axis ≥ 10g,
• Lateral axis ≥ 10g,
• Longitudinal axis ≥ 10g；

The tests should be conducted in accordance with GJB150.18 A -2009, "Military Equipment Laboratory Environmental Test Methods - Shock Tests."

3. User Precautions

The laser emitted by this rangefinder is 1535nm, which is safe for human eyes. Although it is an eye-safe wavelength, it is advised not to look directly into the laser.

When adjusting the parallelism of the optical axis, be sure to cover the receiving lens to avoid permanent damage to the detector due to excessively strong echoes.

This rangefinder module is not airtight. Ensure that the relative humidity of the environment is below 80% and maintain a clean and sanitary environment to prevent damage to the laser.

The range of the rangefinder is related to atmospheric visibility and the nature of the target. Range will be reduced in fog, rain, and sandstorms. Targets like green tree clusters, white walls, and exposed limestone have better reflectivity and can increase range. Additionally, increasing the angle of the laser beam to the target will reduce the range.

Do not emit lasers at highly reflective targets such as glass or white walls within 20 meters to avoid echo overstrength and damage to the APD detector.

Do not plug or unplug cables while the device is powered on.

Ensure the correct polarity of the power supply connection to avoid permanent damage to the equipment.
