Mass
The operating environment with no excessive changes in ambient temperature and humidity, no
vibration and drafts, no influence by magnetic fields and static electricity.
The internal mass may change due to corrosion or other damage caused by the operating environment,
or due to aging. Check the internal mass periodically and correct the internal mass value if necessary.
*1: Even when a tare weight beyond the precision range is placed, the weighing sample can be weighed in
the precision range if using the smart range.
*2: Repeatability using a 1 gram weight within the weighing capacity.
*3: Repeatability using a 100 gram weight within the weighing capacity.
