Specification is +/-(% of reading + fixed offset). Measurement is 1000 samples. Specification may degrade when the unit is subject to an
RF field of 3V/meter, the unit is subject to line spikes of 500V, or an 8kV electrostatic discharge.

For example, if the duty cycle setting is 20%, the actual duty cycle would be in the range of 19% to 21%.

DC current accuracy specifications apply 30 seconds after input current is applied.
