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
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.
