Weight Scale Accuracy: Everything You Need to Know for Importers and Distributors

Choosing the wrong Weight Scale Accuracy can lead to returns, customer complaints, and even the bankruptcy of your business. For instance, if you choose an ordinary smart scale to enter the market of high-end chain gyms, this will definitely affect your customer satisfaction and brand reputation. In this article today, we will detail the Accuracy of each type of scale and how to choose the appropriate Accuracy for your business.

Why do you have to pay attention to the accuracy of the Weight Scale?  

Weighing Scale: The Difference Between Accuracy and Precision

Weighing Scale Accuracy: This refers to how accurate the measurement results provided by the weighing scale are, and how closely they match the actual values of weight, body fat, heart rate, water content, etc. 

Weight Scale Precision: Multiple measurements are required. If the readings are taken repeatedly, will the data fluctuate? How stable is the reading of the intelligent scale? 

For you, the after-sales returns, negative reviews and customer losses of the smart bathroom are all direct losses of profits, and even lead to the failure of the business. 

Only when the accuracy of the intelligent scale ensures the authenticity of the data and the precision of multiple measurements guarantees stability can it reduce post-sale disputes, maintain the reputation of your users or end consumers, and be conducive to long-term repeat purchases and returning customers.

What are the main factors that affect the accuracy of the weighing scale?

1.High-accuracy sensor

The sensor is the foundation for the accuracy and stability of our bathroom scales.

Its material, strain gauge, linear sensitivity, temperature and humidity resistance, assembly process, uneven elasticity, and poor workmanship, all of these can determine whether a scale is accurate, stable, durable, and are also the core components you should focus on when selecting and controlling the quality. 

2. Environmental Factors

Temperature: Since the inner part of the scale is composed of metal strain gauges and circuits, as the temperature rises, the metal expands and the resistance increases; when the temperature drops, the metal contracts and the resistance decreases. This directly affects the electrical resistance output of the sensor, causing the weight or reading zero point to drift and resulting in errors. It is recommended to choose an intelligent scale with high accuracy sensors.

Humidity: It is the "invisible killer" of electronic scales. If it is too humid, it will cause the internal circuits to get damp, leak electricity, and even gradually break down; if it is too dry, it is prone to causing static electricity. Precautionary measures must be taken in advance.

Ground Flatness: The intelligent scale must be placed on a "hard, flat, and stable" surface; a soft or uneven surface will definitely result in inaccurate measurement data. If your users receive the body fat scale and due to an uneven ground or improper use, they obtain data with large errors, they will directly give a bad review. 

3. Calibration method

Single-point calibration: Use a fixed weight of 50kg/60kg as the standard to level the zero point and coefficients, and conduct a one-time baseline calibration. This is suitable for low-end ordinary Bluetooth body weight scales.

Multi-point calibration: Use multiple different weight weights to conduct segmented calibration, such as 20kg, 40kg, 60kg, 80kg, 100kg, and individually calibrate and correct each of the light, medium, and heavy intervals. This can effectively reduce errors and has better stability. It is suitable for high-precision body fat scales, gym scales, and body composition measurement devices for the whole body.

Automatic calibration: The scale has its own calibration function. That is, after each power-on, restart, or leveling, it automatically resets to zero and corrects the initial baseline.

User calibration: Whenever the user is not using the scale for a long time, moves to a different location, or changes the battery, the user steps on the scale once, and the intelligent Bluetooth scale will automatically re-identify the zero point and baseline, completing self-calibration.

4. Power stability

During the entire weighing process of the Bluetooth WiFi scale, the voltage and current of the battery or power supply must remain stable without fluctuations, so that the circuit and sensors can function properly. If the voltage and current output of the power supply are unstable, the intelligent scale will immediately have inaccurate data or skip numbers. This is an essential hidden core configuration that you must pay attention to when choosing the product.
