Input Impedance
Approx. 10MΩ in parallel with < 100pF, all ranges.
Maximum Input 450V dc or peak ac continuous on 500mV range.
1000Vrms on other range.
Crest Factor Range 3.0 at full scale.
dBm (ref 600Ω)
63.8dBm ~ -97.7dBm.
When the input exceeds the full scale of the selected range, the display will
indicate over-range: “—OL—“.
