BS Series Manual

Thank you for purchasing the American Weigh

BS-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 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 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.
