Current
Type
: 4 full differential, DC coupled.
Channels A, B, C, D Input Range
: 10 - 200% of Rated Probe Input (Dranetz
probes)
RMS Accuracy
:
±0.1% of Reading ±0.05% Full Scale plus Probe Accuracy, 3KHz bandwidth (1 second
rms readings)
Phase
Each voltage/current pair (i.e. Channel A voltage, Channel A current) are sampled
simultaneously to preserve phase relationship.
Frequency
Two ranges, user selectable.
For 4400:
• 30 - 70 Hz default, with up to 25% Vthd
• 15 - 30 Hz
Accuracy
: ±0.2% of reading
Environmental
All specifications are met over the operating range with influence factors as per IEC
61000-4-30 Class A.
