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. |
| ■ Auto-range function |
|---|
| Fungsi “Rentang Otomatis” secara otomatis menyesuaikan rentang pengukuran ke tegangan keluaran yang ditentukan ketika nilai kalibrasi yang diatur dalam Kalibrator Internal diterapkan. Tegangan keluaran dapat dipilih dari 5 V, 8 V, dan 10 V. Bahkan mereka yang belum terbiasa dengan penguat regangan pun dapat dengan mudah mempersiapkannya untuk pengukuran. |
| ■ E-terminal Switching function |
|---|
| Fungsi “Pengalihan Terminal-E” mengalihkan potensi pelindung (Terminal-E) kabel sensor ke [Input COM] atau [GND] penguat, dan melakukan tindakan pelindungan yang sesuai untuk lingkungan pemasangan jembatan sensor. Jika Terminal-E tidak terhubung ke sasis transformator, dll., pengaturan sakelar ke [Input COM] akan meningkatkan efek pelindungan dan mengurangi gangguan kebisingan |
