PROVA 700 : Đồng hồ đo MilliOhm

prova-11

PROVA 700 là Đồng hồ dùng để đo điện trở nhò hàng milli-Ohm, độ phân giải 1μΩ, độ chính sai số 0.05%.



FEATURES / TÍNH NĂNG

Features:
  • Độ phân giải tốt nhất / Best resolution 1μΩ. Accuracy 0.05%
  • Dòng điện tối đa / 5A (120 mΩ) max. test current.
  • Chọn thang đo tự động / bằng tay / Manual or Auto Range. (There are 6 ranges of current measurement, and furthermore 3 ranges in each current range.)
  • Measurement of resistive and inductive materials (Two terminal measurement; Four terminal Kelvin measurement)
  • Programmable Hi-Lo alarm with memory of 20 data.
  • Auto-judgments of Hi (readings higher than Hi-Limit), Lo (readings lower than Lo-Limit) and Pass (readings between Hi-Lo Limits).
  • Chuông báo mức cao, mức thấp / Alarm (beeper) for Hi and Lo.
  • Readings Hold function.
  • Đo chiều dài cable / Cable length measurement. The length unit can be selected between Meter (M) and Feet (FT).
  • Resistance measurement results excluding cable resistances.
  • Memory of 3,000 measurement data.
  • Large LCD (5-digit) with backlight (users can choose to disable it).
  • Sử dụng pin sạc / Rechargeable batteries and AC adaptor.
  • Low battery (voltage) alarm.
  • Low power consumption.
  • Communicate with PC via RS232C (to USB bridge) cable.
  • Application: various low-resistance (cables) measurement; contact resistance measurement, …etc.
