The lower measuring ranges are only specied from 5% (does not apply to DC current / AC
current measurements with the current probe)
2
Frequency of AC voltage 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
+/- (2.5% of m.v. + 3 digits) for 400Hz to 750Hz / +/- (5.0% of m.v. + 3digits) for 750Hz to 1000Hz
