3. PRECAUTIONS
To get the optimum performance from the balance and acquire accurate weighing 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.
Warm up the balance for at least 30 minutes. Plug in the AC
adapter as usual.
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 sample). When a
sample could have a static charge, the weighing data
is influenced. Ground the balance and try the
following:
Eliminate the static electricity by AD-1683 as an accessory.
Or try to keep the ambient humidity above 45%RH.
Or use the metal shield case.
Or wipe a charged plastic sample with the wet cloth.
This balance uses a strong magnet as part of the
balance assembly, so please use caution when
weighing magnetic materials such as iron. If there is a
problem, use the underhook on the bottom of the
