3. Installation Considerations, Weighing Preparation and Precautions
Prepare the following installation conditions in order to bring out the full performance of the balance.
Install the balance in an environment where the temperature and humidity are not excessive. The
best operating temperature is about 20°C ±2°C at about 45% to 60% RH relative humidity.
Install the balance where it is free of dust.
The weighing table should be solid. (An anti-vibration table or stone table is ideal)
Place the balance on a horizontal table, and make sure that it is not tilted.
Install the balance in a stable location, avoiding vibration and shock. Corners of rooms on the first
floor are best, as they are less prone to vibration.
Install the balance where it is not affected by heaters or air conditioners.
Install the balance where it is not exposed to direct sunlight.
Install the balance away from equipment which produces
magnetic fields.
Level the balance with the leveling feet and bubble spirit level.
Refer to "3.1. How to adjust the level of the balance".
Be sure to warm up the balance before use for at least an hour, or at least four hours for BA-6E / BA-
6DE, with the AC adapter connected to the power supply.
Adjust the sensitivity of the balance before using it for the first time or after having moved it to another
location so that accurate weighing can be performed. For details, refer to the detailed instruction
manual listed in "1.1. Detailed Manuals".
Caution Do not install the balance where flammable or corrosive gas is present.
