For self-generated heat caused by current input, add 0.00008 × I² % of r 15 × I² μA to the current accuracy. ‘I‘ is the current reading [A]. The infl uence from self-
generated heat continues until the temperature of the shunt resistor inside the DEWE3-Chassis lowers even if the current input changes to a small value.
