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 suf 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 sen-
sor.
• 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.
