Web2. Connect the device under test in loop on the low side so that the current flow is from + to - . 3. Connect a suitable voltage measurement device such as a DMM or an Oscilloscope on the output side. 4. Turn on the device and read the current on the voltage measurement device in the mV range as if it were mA/µA/nA. WebWhat is a coaxial shunt? A shunt resistor is placed directly into the current path. It is therefore not floating, and is normally only used where circuit potentials are low. The voltage across the shunt provides an absolute measurement of current. A ‘coaxial’ shunt is a resistor that has been designed to have almost no inductance (e.g. 2 nH).
