An image showing the scale's ability to switch between 8 units: grams (g), kilograms (kg), carats (ct), ounces (oz), troy ounces (ozt), grains (gn), pennyweights (dwt), and taels (tl). Examples of different unit readings are displayed.
The scale supports the following units: grams (g), kilograms (kg), carats (ct), ounces (oz), troy ounces (ozt), grains (gn), pennyweights (dwt), and taels (tl).
Calibration
Regular calibration ensures the accuracy of your scale. Use the provided 100g calibration weight.

A four-step visual guide for calibrating the scale. Step 1: Turn on the device. Step 2: Press and hold the 'M' button until '100.000g' is displayed. Step 3: Press 'M' again; 'CAL' will flash, followed by the desired calibration weight. Step 4: Place the 100g calibration weight in the center of the platform, and 'PASS' will be displayed to confirm successful calibration.
- Step 1: Turn on the scale by pressing the ON/OFF button.
- Step 2: Press and hold the MODE button (M) until the display shows "100.000g".
- Step 3: Press the MODE button (M) again. The display will flash "CAL", followed by the calibration weight value (e.g., "100.000g").
- Step 4: Carefully place the 100g calibration weight in the center of the weighing platform. The display will show "PASS" to indicate successful calibration. Remove the weight.
Maintenance
- Keep the scale clean by wiping it with a soft, damp cloth. Do not use abrasive cleaners.
- Avoid exposing the scale to extreme temperatures, humidity, or direct sunlight.
- Store the scale in a dry, stable environment.
- Ensure the protective wind cover is used during operation to prevent external interference.
