1.3 Environmental conditions and safety
1）Please avoid the following harsh conditions
· The temperature is below or above: -10 degrees to 40 degrees
· Ungrounded outlet
· Excessive vibration
· Unstable or fragile surface
· Where there is wind or fan running directly on the scale surface
· Shared socket
· Dust or dirt
· Direct sunlight
· Poor air circulation
· High humidity
2）Environmental protection
The scale should be placed in a dry and liquid-free environment. When
the scale is placed in a high humidity or humid environment, be sure to
avoid liquid overflow or spray directly on any surface of the scale.
3）Personal safety
It is very important to pay attention to personal safety when maintaining
and operating equipment. The warnings in this manual are necessary
for safe operation. Before operating the scale, be sure to read all
warnings carefully.

4）Observe the following safety measures
· Before you open the lid of the scale at any time, turn off the power
switch of the scale and unplug the power plug.
· The power plug of the scale should be tightly inserted into the power
socket and properly grounded.
· Whenever inserting and unplugging the power plug, the head of the
power cord should be held. Pulling on the cable will cause the circuit to
be disconnected or short-circuited, causing a fire.
· Maintain a working environment free from electrostatic interference.
· The power outlet must use the correct rated voltage.

The scale must be placed on a flat and
stable surface. Keep the scale away
from fans, ventilation systems or direct
passages of strong air currents.
Because of these air turbulences, they
can be picked up by the very sensitive
weighing platform of the scale and may
cause incorrect weight readings.
