Gemini-20 Manual
Thank you for purchasing the American Weigh Gemini-
20 portable milligram 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. Overloading the scale will permanently
damage it! Avoid any exposure to extreme heat or
cold. Your scale works better when operated at normal
room temperature. Always allow the scale to acclimate
to normal room temperature for at least one hour
before use.
Give your scale sufcient 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 distance to
other electronic equipment can all 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 as this may
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.
