Input Impedance
10 Me in parallel with <100 pF
Note
In the dual display mode, when the volts ac and volts dc functions are
selected, the 10 M
Ω
dc input divider is in parallel with the 1 M
Ω
ac
divider.
Normal Mode Rejection Ratio
>80 dB at 50 Hz or 60 Hz, slow and medium rates
>54 dB for frequencies between 50-440 Hz, slow and medium rates
>60 dB at 50 Hz, fast rate (Note: Fast rate has no filtering)
