300 mV - 300V ranges ≥3:1, 1000V range ≥3:1 decreasing to ≥1.41:1 as input voltage increases to 1000V (peak
voltage not to exceed 1414V).
Measurement Range: 300 mV range from 10% to 100% of range.
3V - 1000V ranges from 5% to 100% of range.
For frequencies > 100 kHz 30% to 100% of range (all ranges).
