Webcalibrate a shunt through its full useable current range is failing to calibrate it. The shunt will continue to change resistance until it reaches thermal equilibrium at the applied current. For large, high current shunts, this can take over an hour. Only at this point should measurements begin. Heat distribution in a shunt also affects its ... WebJan 29, 2024 · A shunt resistor is generally needed to measure microamps and nanoamps. A fourth option is to use a specialized circuit or part for measuring voltage across a shunt resistor, such as an INA169. The …
