3. PRECAUTIONS
To get the optimum performance from the balance and acquire accurate weight data, note the
following:
3-1 Before Use
Install the balance in an environment where the
temperature and humidity are not excessive. The best
operating temperature is about 20°C / 68°F at about
50% relative humidity.
Install the balance where it is not exposed to direct
sunlight and it is not affected by heaters or air
conditioners.
Install the balance where it is free of dust.
Install the balance away from equipment which
produces magnetic fields.
Install the balance in a stable place avoiding vibration
and shock. Corners of rooms on the first floor are best,
as they are less prone to vibration.
The weighing table should be solid and free from
vibration, drafts and as level as possible.
Level the balance by adjusting the leveling feet and
confirm it using the bubble spirit level.
Ensure a stable power source when using the AC
adapter.
Plug in the AC adapter and warm up the balance for at
least 30 minutes.
Calibrate the balance before use or after having
moved it to another location.
Caution
Do not install the balance where flammable or corrosive gas is present.
3-2 During Use
Discharge static electricity from the material to be
weighed (hereinafter referred to as the sample). When
a sample could have a static charge, the weight data is
influenced. Ground the balance and try the following:
Eliminate static electricity using the optional
AD-1683 DC static eliminator.
Try to keep the ambient humidity above 45%RH.
Use a metal shield case for a charged sample.
Wipe charged plastic samples with a moistened
cloth.
