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.
