AC Voltage:
• Five Ranges: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V, 750.00 V
• Measurement Method: AC coupled true rms - measures the AC component with
up to 400 VDC bias on any range.
• Crest Factor: Maximum 5:1 at full scale
• Input Impedance: 1 MΩ ± 2% in parallel with <100pF on all ranges
• Input Protection: 750V rms on all ranges (HI terminal)
DC Voltage:
• Five Ranges: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V, 1000.00 V
• Measurement Method: Sigma Delta A-to-D converter
• Input Impedance: ~10 MΩ all ranges (typical)
• Input Protection: 1000V on all ranges (HI terminal)
