AC measurement (TRMS)

20 A for max. 30 sec. at reduced accuracy

Frequency range 50 Hz...10 kHz

All AC voltage ranges are specified from 5% to 100% of the range
Measurement of AC+DC

Frequency range 0...1000 Hz

20 A for max. 30 sec. at reduced accuracy
Measurement of alternating voltage for frequency >5 kHz

Frequency band 5...100 kHz
Accuracy was determined in the temperature range from 18
below 75%. For distorted current, the error is increased by (2% m.v. + 2% of full scale) for a
crest factor <3.0.
