1.2 Warnings
l
Avoid lengthy exposure to extreme heat or cold. Your scale works best when
operated at normal room temperature. Always allow the scale to acclimate to
a normal room temperature before use.
l
Allow sufficient warm up time. Turn the scale on and wait for a few minutes if
possible. This will give the internal components a chance to stabilize before
weighing.
l
These electronic scales are precision instruments. Do not operate near an
in-use cell phone, radio, computer or other electronic device. These devices
emit RF and can cause unstable scale readings. If your scale ever performs
poorly, try moving the scale to a different room or location.
l
Avoid using in heavy vibration and airflow conditions.
l
Read the weight reading in short time after loading. The output signature of
load cell and electronic circuit may be little influenced after weighing for a
long time.
