(1 Related to the nominal values, the accuracy defines the maximum deviation between an adjusted values and the true (actual) value.
Example: a 1000 A model has min. 0.2% current accuracy, that is 2 A. When adjusting the current to 300 A, the actual current on the DC terminal is allowed to
differ max. 2 A from the set value, which means it could be between 298 A and 302 A.
(2 RMS value: LF 0...300 kHz, PP value: HF 0...20MHz
(3 The display error adds to the error of the related actual value on the DC terminal
