WebFor current measurements, It has a built-in 50 Ω shunt resistor that can be applied in software, allowing engineers to measure current either up to 2 mA or 20 mA, user-selectable. IOLITE chassis are available in an “IOLITEs” benchtop model, which accepts up to 8 multi-channel modules (seen in the picture above). An ammeter shunt allows the measurement of current values too large to be directly measured by a particular ammeter. In this case, a separate shunt, a resistor of very low but accurately known resistance, is placed in parallel with a voltmeter, so that virtually all of the current to be measured will flow through the shunt (provided the internal resistance of the voltmeter takes such a low portio… WebAmpere, so in practice the Ampere is realized by measuring voltage across a current shunt, using Ohm’s Law (I=E/R). Accurate electrical current measurement is critical to the power and electrical test industries.
