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.
Plug in the AC adapter and warm up the balance for at
least 30 minutes.
Calibrate the balance periodically for accurate weighing.
When the balance is installed for the first time or has been
moved, warm up the balance for at least 12 hours to allow
the balance to reach equilibrium with the ambient
temperature, and then perform calibration before use.
Caution
Please confirm that the AC adapter type is correct for your local voltage and receptacle type.
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. Try to keep the ambient humidity above
45%RH or use the metal shield case.
