Amazon カスタマー 5 0.001g単位で計測できますが、実質は、最後の桁は参考値として、0.01g 単位なら、かなり正確です。以前、amazon で購入した別の電子スケールだと、0.01g~0.03g 程度の軽いものは、不安定で反応せず、0.00g と表示されることもありましたが、この商品は、0.01g の物でも、きちんと反応します。この価格でこの精度なら、とてもコスパはいいと思います。使い方や、校正方法は、説明書に書いてありますが、英文なので、翻訳しやすいように、スキャンした文章を記載しておきます。User ManualThank you for purchasing this scale (0.0019).Ptease readthe operating instructions carefully before use.
