Description
Fluke 772 Milliampere Clamp Meter adalah alat ukur profesional yang dirancang khusus untuk teknisi instrumentasi dan kontrol proses dalam mengukur arus DC kecil (mA), terutama pada sinyal standar 4–20 mA.
Secara umum, alat ini memungkinkan pengukuran arus dilakukan tanpa memutus rangkaian (loop) dengan metode clamp (penjepit), sehingga proses pengukuran menjadi lebih cepat, aman, dan tidak mengganggu sistem yang sedang berjalan.
FITUR Fluke 772
- Pengukuran 4–20 mA tanpa memutus loop → lebih cepat & aman
- Akurasi tinggi ±0,2% → hasil presisi industri
- Resolusi 0,01 mA → sensitif untuk sinyal kecil
- Fungsi lengkap (measure, source, simulate mA) → alat multifungsi
- Loop power 24V → bisa supply dan test transmitter
- Dual display backlight (mA & % loop) → pembacaan lebih mudah
- Clamp detachable (fleksibel) → mudah digunakan di area sempit
- Fungsi ramp & step output → simulasi sinyal otomatis
- Measurement spotlight → bantu kerja di tempat gelap
- Pengukuran in-circuit (tanpa shutdown sistem) → efisiensi kerja tinggi
