- Input voltage (between 0 and U)
- Max 620 Vdc/460 Vac
- Input resistance Ri = 1 MW in all ranges
- Three?stage attenuator: MT = 1: 1; 1/10; 1/100
- Accuracy: ±2% of full scale range
- Input current (between 0 and I)
- Max: 10 A continuous; 16 A for t< 15 min; 20 A for t<2 min.
- Internal resistance: 30 mW in all ranges
- Two?stage attenuator: MT = 1 V/A; 1/3 V/A
- Accuracy: ±5% of full scale range
