1. "Typical accuracy" means at temperatures of 23 °C ± 5 K, after a warm-up time of more than 25 min, and in a frequency range
of 45 Hz to 65 Hz, 98 % of all units have an accuracy which is better than specified.
Conditions
1 pF...3 µF
error < 0.05 % of reading + 0.1 pF Ix < 8 mA, Utest = 2 kV...10 kV
error < 0.2 % of reading Ix > 8 mA, Utest = 2 kV...10 kV

2. Reduced accuracy of DF at mains frequency or its harmonics. Mains frequency suppression available by precisely selecting
a mains frequency of *50Hz or *60Hz in the "Hz" column.
f = 45...70 Hz, I < 8 mA,
Utest = 2 kV...10 kV
0...10000 % error < 0.5 % of reading + 0.02 % Utest = 2 kV...10 kV
