  • Page 3: Precautions Before Using The Scale

    I. Precautions before Using the Scale Environment The scale should always be used in an environment, which is free from excessive air currents, corrosives, vibration, and temperature or humidity extremes. These factors will affect displayed weight reading. DO NOT install the scale: Next to open windows or doors causing drafts or rapid temperature changes.
