Measurement categories III 600 V (anticipated transient overvoltage 6000 V)
Measurement categories II 1000 V (anticipated transient overvoltage 6000 V)
Measurement method Simultaneous digital sampling of voltage and current, synchronous zero-crossing calculation method
Sampling 500 kHz/16 bit
Measurement frequency range DC, 0.5 Hz to 200 kHz
Synchronization frequency
range
0.5 Hz to 5 kHz
Selectable lower limit measurement frequency (0.5 Hz/1 Hz/2 Hz/5 Hz/10 Hz/20 Hz)
Synchronization source U1 to U4, I1 to I4, Ext (with the motor evaluation installed model and CH B set for pulse input),
DC (50 ms or 100 ms fixed)
Selectable for each measurement channel (U/I for each channel measured using the same synchroni-
zation source)
The zero-crossing filter automatically follows due to the digital LPF when U or I is selected.
Two filter levels for zero-crossing filter (strong or mild)
Operation and accuracy are undetermined when the zero-crossing filter is disabled (off).
Operation and accuracy are undetermined when U or I is selected and measured input is below 30% f.s.
