In "DC" mode, users can measure a direct current value or an alternating
current's direct component.
Rate Accuracy
500 µA 0.2% + 5D
5 mA 0.2% + 3D
50 mA 0.2% + 3D
500 mA 0.2% + 5D
10 A 0.5% + 5D
In "AC" and "AC+DC" modes, users can measure an alternating current's rms
value with/without its direct component (no capacitive coupling in "DC" mode).
Rate accuracy
500 µA 0.5% + 30D
5 mA 0.5% + 30D

500 mA 0.5% + 30D
10 A 2.5% + 30D
Results < 0.2 % are not displayed.

Specifications for direct current superimposed on a sinusoidal signal in the
40 Hz to 10 kHz band, valid from 10 to 100 % of rate.
For the mA and µA range, the "AUTO PK" mode is always active:
Additional error of 2 % for a peak factor between 1 and 1.5.
Additional error of 15 % for a peak factor between 1.5 and 2.
Peak factor is 5 for a 10 A range.
