AC Voltage (AC Coupling Mode/AC + DC Coupling Mode)
Measurement method: AC coupled true RMS - measure the AC
component with up to 400 VDC bias on any range.
Crest Factor: Maximum 3 at full scale.
Input Impedance: 1 MΩ ± 2% in parallel with <100 pF on all ranges.
Maximum input voltage: 750 Vrms on all ranges.
Input protection: 1200V peak on all ranges with gas discharge.

*The accuracy of ACV+DCV is equal to ACV’s with 10 more digits added.
[1] The accuracy of the AC voltage measurement is guaranteed only when the
signal being measured has frequencies higher than what is listed here.
