USER MANUAL
Thank you for purchasing this 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 maximal capacity. Overloading can
permanently damage it!
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 1
hour before use.
Give your scale sufcient warm up time.
Usually 30 seconds to give the internal
components a chance to stabilize before
calibration.
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
on to tray top. Although this scale is
designed to be quite durable, try to avoid
rough treatment as this may permanently
damage the internal sensor.
