The operating environment does not include excessive change of ambient temperature, humidity,
vibration, drafts, 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 When placing the tare weight within the standard range, if using the smart range, the weighing sample
can be weighed within the precision range.
∗2 The repeatability for 1 gram within the weighing capacity.
∗3 The repeatability for 100 gram within the weighing capacity.
