Best resolution 1μΩ. Accuracy 0.05% 5A (120 mΩ) max. test current. 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). Alarm (beeper) for Hi and Lo. Readings Hold function. 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). 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.
