General Maintenance and Care 1. Avoid exposure to extreme heat or cold. Also avoid any type of moisture. Always allow the scale to acclimate to normal room temperature before use. 2. Store the scale in a clean and dry environment. Dust, dirt, moisture, vibrations, drafts, and proximity to other electronic equipment can negatively affect the scale's accuracy and reliability. 3. Handle the scale carefully. Gently place all items to be weighed on the platform. Although this scale is designed to be quite durable, avoid rough handling, as this can permanently damage internal parts. Always avoid shaking or dropping. This is a precision instrument and should be handled with extreme care. Specification and Function 1. Capacity: 500g Accuracy: 0.01g 2. Units: g, oz, ozt, dwt, ct 3.
