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.
