| ■ Isolasi input/output ideal untuk aplikasi sistem – AS2603 |
| Rangkaian isolasi digunakan antara input/output dan catu daya. |

Functions
| ■ Bridge Check function |
|---|
| Fungsi “Bridge Check” secara otomatis mendeteksi pemutusan, hubung singkat, dan kabel putus di setiap sirkuit jembatan. Deteksi kabel yang terputus atau hubung singkat dengan mudah mengurangi waktu persiapan pengukuran dan membantu mencegah masalah pada bagian input.
|
| ■ Cable Length Correction function |
|---|
Jika jarak antara rangkaian jembatan dan penguat jauh, tegangan jembatan akan turun karena resistansi konduktor kabel. Sebelumnya, penginderaan jarak jauh dengan kabel 6 inti dan kompensasi dengan pengaturan numerik (panjang kabel, diameter kawat, dll.) digunakan. (Penginderaan jarak jauh tidak dimungkinkan dengan penguat regangan AC yang menggunakan kabel 6 inti.) Rangkaian produk ini menggunakan rangkaian kompensasi otomatis yang unik untuk mengkompensasi penurunan tegangan jembatan bahkan dengan kabel 4 inti, sehingga memungkinkan pengukuran regangan yang sangat akurat. |
