    (like voltage measurement function) is selected. 4-10 Words AC Sensing Average: RD700 When measurement is taken by "average", no error is caused as the input signal is shine wave with no distortion. However, if the input waveform is distorted sine cave or non-sinusoidal wave, conversion to root-mean -square values is very difficult, resulting in a large error.

  • Page 9: Measurement Procedure

    NMRR (Normal Mode Rejection Ratio) NMRR is the DMM's ability to reject unwanted AC noise effect, which can cause inaccurate DC measurements. NMRR is typically specified in terms of dB (decibel). This series has a NMRR specification of >60dB at 50 and 60Hz, which means a good ability to reject the effect of AC noise in DC measurements.
