Calibrate the Balance - If it’s manual calibration, use certified calibration weights. - For auto-calibration models, follow on-screen instructions. - Calibration ensures accuracy in measurements. ⚖️ 3. Tare the Balance - Place the container or weighing paper on the balance. - Press the “Tare” or “Zero” button to set the display to zero. This subtracts the container’s weight. 4. Weigh the Sample - Carefully add the sample into the container. - Wait for the reading to stabilize (usually indicated by a stable icon or beep). - Read the weight from the digital display. 5. Repeat or Change Units (if needed) - You can press the unit button to switch between grams, milligrams, ounces, etc., depending on your needs.   6. Clean After Use - Remove any spilled substances. - Wipe the surface with a soft, lint-free cloth. Do not use harsh chemicals unless specified by the manufacturer. ⚠️ Tips for Best Use: - Avoid touching the container with bare hands (use tweezers or gloves to avoid adding extra weight from oils or moisture).- Use a draft shield if available to minimize airflow interference.- Do not overload the balance beyond its maximum capacity—it can damage the sensors.
