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.

This scale has been calibrated before shipment, how-
ever accuracy may be affected by variations of gravity,
shipment, handling, and changes in temperature.

The delicate weighing load cells have
been damaged by misusing the scale
(i.e. it was shocked, dropped or
overloaded). You can try recalibrating the
scale. If the load cell has not been
damaged too much it will work
again after recalibration.
