Thank you for purchasing the American Weigh
CG2-Series 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 acclimate to normal room temperature for at least one hour before use.
Give your scale sufficient 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.
