Can measure DC resistance such as a low shunt resistance with high speed and high accuracy using the DC four-terminal method. Shunt resistance of 0.1 mΩ can be measured with an accuracy of ±1%. The resistance meters provide advanced contact-check, comparator, and data export functions. In addition, its intuitive user interface and strong noise immunity are suitable for use in automated systems.

Features
The shunt resistance meters provide higher efficiency and accuracy. Using the AVERAGE function, 0.1mΩ ±1% shunts can be mea-sured at a high ±0.16% accuracy and high resolution of 0.01 μΩ
Scaling Function Corrects Differences to Simulate Testing Component Mounted on BoardThe scaling function can correct the differences in the measurement resistance values between the component alone and the component mounted on the board. The function is useful in testing a current detection resistor for low resistances such as a shunt resistance.
OVC (Offset Voltage Compensation)Thermal EMF occurs at the contact point of different metals. This voltage affects measurements, and if large enough, can cause measurement errors. The offset voltage compensation function minimizes the effect of thermal EMF to maintain measurement accuracy. Particularly when measuring shunt resistances and low resistances where the detection voltage is small, OVC is essential to maintain accuracy.
Maximum Measurement Current of 1 A and Pulse Application Function Reduce Heat Generation of SamplesA pulse application function that applies current only during measurement reduces heat generation that may cause unstable resistance measurement values. In addition, the maximum measurement current of 1 A, a thermal electromotive force cancellation function, and an ultra-low noise measurement circuit minimize the variation in the measurement values.
Easy Setup Using Numerical KeypadThe user-friendly interface features a high-contrast graphic LCD display, function keys and numerical keypad. Numbers can be input from the numerical keypad easily and speedily to configure the settings for the comparator.
