Precautions for Installing the Balance
To ensure that you get the most from your balance, please try to follow
these conditions as closely as possible:
□ The best operating temperature is about 20°C
/ 68°F at about 50% Relative Humidity.
□ Try to ensure a stable power source when using
the AC adapter.
□ Please warm-up the balance for at least one
hour. Plug-in the AC adapter as usual.
□ The weighing room should be free of dust.
□ The weighing table should be solid and free
from vibration, drafts (such as frequently open­
ing doors or windows) and as level as possible.
□ Keep the balance level by using the bubble spirit
level.
□ Don’t install the balance near heaters or air
conditioners.
□ Don’t install the balance in direct sunlight.
□ Don’t use the balance near other equipment which
produces magnetic fields.
□ Corners of rooms are best as they are less
prone to vibrations.
□ Calibrate the balance before using and after
moving it to another location.
Do not place or use the balance where there
is flammable or corrosive gas present.
