The lower measuring ranges are only specified from 5% (does not apply
to DC current / AC current measurements with the current probe)
2
Signal bandwidth 40 Hz to 1 kHz
3
In the case of a mixed signal (AC + DC), only the purely AC component is
taken into account
4
As the frequency increases (over 400 Hz), the accuracy deteriorates
+/- (1.5% of m.v. + 3 digits) for 400Hz to 750Hz / +/- (2.0% of m.v. + 3digits)
for 750Hz to 1kHz
5
Frequency of AC current up to 400 Hz

Specification is valid for capacitances > 10 nF
