How to Calibrate Xiaomi Scales: A Step-by-Step Guide

Xiaomi’s modern smart scales have proven to be accurate and reliable for monitoring physical shape. However, like any electronic measuring device, they require periodic adjustments to maintain high accuracy. If you notice that the numbers on the display are floating or different from the expected values, it’s probably time to calibrate.

The process of restoring accuracy does not always involve complex engineering manipulations; in most cases, it is enough to perform a standard reset procedure or correctly place the device on the surface, and ignoring installation recommendations can lead to systematic errors that the user mistakenly perceives as a breakdown of the sensors.

In this article, we will discuss in detail all the known ways to adjust the scales Mi Body Composition Scale and Mi Smart Scale.You will learn how to prepare the device, what actions to perform through the Mi Fit application (or Zepp Life) and how to diagnose malfunctions if software methods do not help.

Causes of failure of indications and diagnosis

Before you start the active adjustment phase, you need to understand the nature of the error that has arisen. The strain gauges installed inside the platform are extremely sensitive to external factors. Even a slight skewed floor or pile of the carpet can distort the result by several kilograms, making further measurements meaningless.

A common cause of zero floating is the discharge of the batteries. At low voltage, the scale processor may not process the sensor signal correctly. It is also worth considering the temperature regime: if the device has just been introduced from the cold into a warm room, the condensation and thermal expansion of the materials can temporarily disrupt the electronics.

⚠️ Warning: Do not attempt to calibrate the scales if moisture, dust or greasy spots are visible on the surface of the platform or legs.This can lead to contact closure or slippage, which is dangerous for the user.

For primary diagnosis, follow the following steps:

• 🔋 Check the battery charge – replace it with new ones, even if the old ones look like they’re working.
• 🧹 Clean the surface of the scales and the floor below them from any foreign objects.
• 🌡️ Let the device stand in the room. 1-2 the hour for acclimatization, if it was in a different temperature mode.

If after eliminating these factors, the problem persists, we proceed to the procedures of software and hardware calibration.

Preparation for calibration: surface selection

The key to measuring accuracy is the surface on which the scales are standing, and the ideal is a hard, flat floor, such as tile, laminate or linoleum, and soft coatings, such as carpet or thick carpet, absorb pressure, which causes the scales to show low values.

If you have to use a scale on a carpet, some models allow you to recalibrate it for this type of surface. However, Xiaomi manufacturers strongly recommend using a solid base. Before starting the procedure, make sure that the floor does not have a slope that can be seen visually or with the help of the building level.

💡

Use a wet wipe to clean the platform before weighing, but be sure to wait for the surface to dry completely so that moisture does not get inside the body through the gaps.

Procedure for preparing the installation site:

1. Remove all items from the weights installation area.
2. Wipe the floor with a dry cloth to prevent slipping of the legs.
3. Make sure the legs of the scales fit tightly to the floor and do not stagger.

Installation is the most common reason users are looking for ways to calibrate the scales, although the problem lies solely in the physical location of the device. 10-15 Free space from all sides.

Resetting and automatic calibration procedure

Most Xiaomi smart scales don’t have a physical reset or calibration button in the classical sense, instead using an automatic calibration algorithm when turned on. To start this process, you need to completely discharge the device or artificially initiate a reset of the sensors.

The most effective method is to remove the batteries from the compartment and leave the scales alone. 15-20 This will allow the capacitors inside the circuit to completely discharge and reset the accumulated errors in the memory of the controller.

After installing the new batteries, the screen should blink, showing the symbols of calibration or zero, at which point the platform should be completely empty. If the display immediately appears weight, do not panic - sometimes you need to repeat the cycle of on 2-3 times.

There is also a “forced weighing” method for some firmware versions:

• 👣 Stand on the scale, wait for the screen to turn on.
• 📉 Wait for the weight to come on, but don’t go off right away.
• 🔄 Get off the scale, wait for the screen to turn off.
• 🔁 Repeat the procedure. 3-4 time-to-time stabilizing.

⚠️ Attention: During the calibration process (screen blinking or "0.00"), you should not touch or blow on the scales. Any movement of air or floor vibration can knock the zero setting.

Setup via Mi Fit and Zepp Life

While the main calibration of weight sensors is at the hardware level, the software part is also important for correct data display and synchronization.The Zepp Life app (formerly Mi Fit) allows you to calibrate calculated metrics such as fat percentage, muscle mass and water based on the anthropometric data you input.

The algorithms need to be able to work correctly, and you need to specify your age, height, and gender, and if that data is wrong, the scales will show the correct weight, but the body composition will be calculated with an error, which the user may perceive as a malfunction, and go to the user profile and double-check all the parameters.

Sometimes you need to re-tether the device to eliminate software glitches:

1. Open the app and go to profile.
2. Select your scales from the list of devices.
3. Click on “Delete Device” or “Untie”.
4. Turn off Bluetooth on your phone, then turn it on again.
5. Perform re-pairing by following the instructions on the screen.

Some versions of firmware have a "Target" or calibration function through the app menu, although it is rare. OTA-Update (firmware update), be sure to install the latest version, as manufacturers often fix the calculation algorithms in new releases.

Table of error codes and indicators

When calibration is attempted or routinely used, scales can signal problems through a screen or flashing indicators, and understanding these signals will help quickly troubleshoot the problem without going to a service center.

If the Err is constantly burning on the screen even after the battery is replaced and discharged, this may indicate physical damage to the strain gauge, which often happens if a heavy object is dropped on the scale or stood on the edge of the platform, creating a critical bend.

💡

A persistent error of "Err" after all reset attempts in 90% of cases indicates a physical malfunction of the sensors, requiring repair or replacement of the device.

Specificity of calibration of different models

Xiaomi’s scale range is extensive and procedures may vary slightly. The Mi Smart Scale 2 has more sensitive sensors than the first version, so the floor level requirements are higher. The Mi Body Composition Scale 2 (with metal contacts for body composition analysis) also requires clean feet to pass current.

For professional models like the Mi Scale 2, there is a hidden diagnostic mode, but it is only available through special engineering utilities on Android that are not designed for the average user.

If you have a color screen model or additional features (such as integration with Google Fit or Apple Health), make sure that synchronization does not block the balance.

Frequent Questions and Challenges (FAQ)

Compliance with these simple rules of operation will allow your Xiaomi scales to last long and show accurate results. Remember that electronics love stability: a permanent installation site and timely replacement of power is the key to success.
