Calibrating DC Current Shunts: Techniques and - Ohm-Labs
... Most metrology shunts are designed for use up to continuous full current, but excessive current on any shunt can overheat and permanently shift its value. To estimate type A uncertainty for temperature, a minimum of 20 ppm (0.002 %) per degree Centigrade should be added. For example, if a lab claims ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
