American Weigh BT-500
Thank you for purchasing the American Weigh BT500 backlit touchscreen digital 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 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 acclimatize 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.

handled with extreme care.
Only operate the scale on a stable, vibration free
