WebJun 24, 2024 · Measuring Higher Currents (Amps) / Removing the Shunt From the Circuit. At higher currents (mAs and up), a large current measurement shunt will create an unacceptable voltage drop (volts) causing the downstream system to be inoperable. You can remove the current shunt be placing a physical or solid state relay across the shunt. WebThe main purpose of a current shunt in calibration is to measure a high current range. If you are looking for a cheaper with higher accuracy standard (above 4:1), compared to a clamp meter, then this is a good choice. Common accuracy specifications of current shunts are ±0.1%, ±0.25% or ±0.5%.

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… WebThe word 'shunt', which has various meanings that include 'divert', 'avoid', and 'divide', conventionally refers to a resistor placed in parallel with an ammeter to shunt current.
