Technical specifications
(1 Related to the nominal values, the accuracy defines the maximum deviation between an adjusted values and the true (actual) value on the DC output
Example: a 80 V model has min. 0.1% voltage accuracy, that is 80 mV. When adjusting the voltage to 5 V, the actual value is allowed to differ max. 80 mV, which
means it might be between 4.92 V and 5.08 V.
(2 The display error adds to the error of the related actual value on the DC output
(3 For technical specifications of the analog interface see
„3.5.4.4 Analog interface specification“ on page 53
