Input Impedance

10 MW in parallel with <100 pF

Note

In the dual display mode, when the volts ac and volts dc functions are selected, the 10 MW dc input divider is in parallel with the 1 MW ac divider.

Normal Mode Rejection Ratio

>80 dB at 50 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)
