AC measurement capacity is with 20-30% reservation on base of the meter measurement range Outstanding DC measurement capacity, more than 70% of the AC measurement range High accuracy, AC measurement accuracy up to class 0.5 or class 1.0; Typical DC measurement error is at 0.5%-2% for 0.1class CT. Small phase error, typical phase shift is at 1-10; Additional compensation not needed Good isolation from Primary to Secondary Very reliable and stable performance at different temperature conditions Frequency: 50Hz/60Hz Ambient Temperature: -40oC -- 70oC
