American Weigh Scales

AMW -DISC User’s Manual 300 x 0.1g

Thank you for purchasing the American Weigh Disc Scale. Please read all operating instructions carefully before use. This electronic scale is a precision instrument. With normal care and proper

treatment, it will provide years of reliable service.

• Never load the scale with more than the maximum capacity.

• Avoid any exposure to extreme heat or cold. Your scale will work better when operated at normal room temperature. Always allow the scale to acclimate to surrounding temperature for at least one hour before use.

• Give your scale suffi cient warm up time. Usually 30-60 seconds before calibration to give the internal components a chance to stabilize.

• Keep your scale in a clean environment. Dust, dirt, moisture, vibration, air currents, and a close proximity to other electronic devices can cause an adverse effect on the reliability and accuracy of your scale.

• Handle with care. Gently apply all items to be weighed onto tray top. Although this scale is designed to be quite durable, try to avoid rough treatment which can permanently damage the internal sensor.

• Avoid shaking, dropping, or otherwise shocking the scale. This is a precision instrument and must be handled with extreme care.

•Only operate the scale on a stable, vibration free surface.
