Xiaomi LS5 MiHome Duka Laser Meter with Touch OLED Display Instruction Manual

Product Overview

Main parameters

• The number of measurements is obtained based on the laboratory environment (5 meters distance, 300LX brightness).
  The actual number of daily measurements will have a deviation of about plus or minus 500 times.

• General conditions: strong reflectivity in the laser/infrared irradiated area (e.g. painted white walls), dark background lighting and operating temperature of 15°C-35°C. At this point it is important to consider An error effect of plus or minus 0.05 mm/m.
• Unfavorable conditions: weak reflectivity of laser irradiated area {such as black cardboard, polished tiles), strong background illumination and an operating temperature of <-10°C or >45°C. At this time to consider a plus or minus 2 mm / m error impact.

Suggestions on how to operate

1. Laser distance measurement, in order to ensure the accuracy of the measurement, the rangefinder needs to remain stationary. When the hand is shaking, the data error is very large, and nay not be able to obtain data.
2. Please avoid blocking the light-emitting port and receiving lens when measuring.
3. Based on physical principles, when measuring on some specific object surfaces errors can occur, for example transparent surfaces (water, glass), surfaces that reflect surfaces (polished metals), porous surfaces (e.g. soundproof materials)If necessary, reflective target paper (e.g. white paper} can be placed on top of these objects.
