* Accuracies figures are statical ones such as static condition on table, neglecting effect of noise.
* Measuring limit is at the condition of D<0.5 at 1 kHz
  For example, in case of serial DCR is over 0.3ohm at 100microH, it is out of 1 limit (Near to D=1, accuracy is out of 1 limit though can be displayed.)
