Kitchen scales are mainly used for weighing ingredients in the kitchen, with a focus on small range and high precision, suitable for fine weighing needs such as home baking, complementary foods, tea drinks, and manual blending. They also support switching between multiple weight units.

1、 Technical specifications

1. Weighing performance parameters

Rated range: 5Kg, covering all household food weighing needs;

Division value: 0.1g, minimum weighing capacity 0.2g;

Weighing units: g/kg/oz/lb, default unit g, unit switching order g-oz-lb-kg;

Fault tolerance and protection: Overload display shows EEEE, startup does not return to 0 (unstable) display, shutdown 10 seconds after UNST shutdown; The peeling range is 30g, the zeroing range is 29.9g, and it supports full range zeroing when turned on.

2. Control, display, and power supply

Button: Capacitive touch button, with functions including ON/OFF power on/off, TARE peeling, and UNIT unit switching;

Display: LCD segment code display screen;

Power supply: Rated 4.5V, if the voltage is below 2.6V, the screen will display LO low power reminder;

Power saving setting: It will automatically shut down after being idle for 60 seconds.

3. Calibration standards

Adopting a 2-point calibration mode, the standard weights are 2000g and 5000g, and the calibration process is standardized, resulting in high consistency in factory production.

2、 Standardized calibration operation process

Correctly install the battery, place the scale on a flat and hard surface, and gently press the scale surface diagonally to confirm that there is no shaking;

Press ON/OFF to turn on the device while it is turned off. When the screen is fully displayed, press ON/OFF again (three short and one long) to enter calibration mode;

After stabilizing the internal code on the screen, switch to the 2000G gear and place a 2000g weight to wait for the value to stabilize;

Automatically switch to 5000G gear, place 5000g weight and wait for stability;

The screen displays PASS, indicating calibration completion, and automatically returns to normal weighing mode.

3、 Product functional advantages

High precision weighing: 0.1g division value, meeting the requirements of trace fine ingredients;

Universal for both domestic and international sales: Multiple weight units suitable for domestic and overseas markets;

Multiple intelligent reminders: screen prompts for overload, low voltage, and uneven placement to protect the body;

Touch integrated design: no mechanical gaps, easy to clean, longer service life;

Easy calibration and maintenance: Dual weight calibration, easy for production line and user calibration;

Low power consumption and power-saving: automatically shuts down in 60 seconds, significantly extending the battery life cycle.

4、 Application scenarios

Home baking, baby food preparation, coffee/milk tea blending, manual DIY raw material weighing, cross-border retail of daily necessities, etc.
