Kelvin (4-terminal) connections are used for these low ohmic value products to measure a precise voltage drop across the
resistive element. In these applications the contact resistance, lead resistance, and their TCR effect may be greater than that of
the element itself and could cause significant errors if the standard 2-terminal connection is used. Figure 2 shows a high
impedance measurement system where r5 approaches infinity and Im approaches zero resulting in negligible IR drop through r3
and r4 which negates their lead resistance and TCR effect. With the voltage sense leads E1 and E2 inside of r1 and r2 the
resistance and TCR effect of the current leads, I1 and I2 are negated and only the resistance and TCR of the element R are
sensed. This method of measurement is essential for precise current sensing.
