  • Page 10 4-10 Words AC Sensing Average RMS: 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 11 NMRR (Normal Mode Rejection Ratio) NMRR is the DMM's ability to reject unwanted AC noise effect, which causes inaccurate DC measurements. NMRR is typically specified in terms of dB (decibel). This series has a NMRR specification of >60 dB at 50 and 60 Hz, which means a good ability to reject the effect of AC noise in DC measurements.
