How to use the rangefinder Xiaomi: instructions with photos and tips for accuracy

Xiaomi rangefinders are compact and accurate devices that help measure distance with error to the distance. ±They are in demand both among professionals (builders, designers, engineers) and among ordinary users for household tasks: from measuring the room before buying furniture to calculating the area of the plot. Xiaomi’s range includes both standalone laser rangefinders (such as Mi Laser Distance Meter) and smart bracelets with built-in distance measurement function (such as Mi Smart Band 7 Pro).

Despite the simplicity of the interface, beginners often have questions about how to turn on the device, calibrate it, save results or sync data with a smartphone. In this article, we will analyze all the nuances from basic settings to advanced features, and give tips for increasing the accuracy of measurements. If you just bought a Xiaomi rangefinder or plan to do so, here you will find answers to all the key questions.

What models of rangefinders Xiaomi produces

Xiaomi offers several types of devices with the function of measuring distance, which can be divided into three categories:

• 📏 Autonomous laser rangefinders: specialized devices for high-precision measurements (for example, Mi Laser Distance Meter 2 or Xiaomi Mijia) LDM-1). They work on batteries, are equipped with a display and support connection to a smartphone.
• ⌚ Smart rangefinder bracelets: Some Mi Smart Band models (such as the 7 Pro) have a built-in sensor for approximate distance measurement.
• 📱 Smartphone apps: programs like Mi Home or Xiaomi Smart Camera can use a phone’s camera to estimate distance (less accurate, but no additional devices are required).

The most popular model among professionals remains the Mi Laser Distance Meter 2. It supports measurements up to 50 meters, has a built-in memory for 30 records and can export data in the format of the Mi Laser Distance Meter 2.CSV. For home use is suitable Xiaomi Mijia LDM-1 with a range of up to 40 meters and the function of calculating the area / volume.

If you want maximum accuracy, opt for standalone laser models. For rare measurements (for example, during repairs), a rangefinder bracelet or a mobile application is enough.

Preparation of the rangefinder for work: charging, inclusion, calibration

The device must be prepared before first use. For autonomous laser rangefinders (Mi Laser Distance Meter 2, Mijia) LDM-1) procedure:
