Produktdatenblatt - TSF-400
The voltage drop between the two connectors of the shunt - induced by the current, flowing through the shunt - is proportional to the resistance of the shunt. Therefore, the intensity of the current flowing through the circuit can be determined in function of the voltage measured between the end-points of the shunt with known resistance value. The diagram illustrates the process of voltage drop (Um) in the shunt (Rs), measured with the instrument (mV). The current intensity value can be read directly on the dial scale in Ampere units. The voltage drop between the measuring points of the available direct current shunts (TSF) is limited to max. 75 mV. Therefore, the measurement vaues of the attached basic instruments are also limited to 75 mV.
