catatan : 1. Akurasi tidak disebutkan dlm spesifikasi dlm deskripsi dan manual book tetapi yang ada hanya precision (presisi) Precision beda dengan akurasi..bisa dicari di Google perbedaan nya. 2. komplain akurasi tidak akan diterima dan klopun ada harus dibuktikan dengan sertifikat kalibrasi yang dikeluarkan oleh lembaga kalibrasi yang berwenang dengan mengacu presisi. 3. setting ada limit bawah utk on dan limit atas off sehingga akurasi menjadi kurang berarti / tidak ditekankan tetapi yg ditekan kan presisi..
