Note
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).
Results < 0.2 % are not displayed.

Note
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.
