Precautions:
-Please check the capacity. Never load the scale with more than the maximal capacity.
-Avoiding 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 calibrating 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 stable, vibration free surface.
