Keithley 2010 User Manual

Crest factor
AC voltage and current accuracies are affected by the crest factor of the waveform, the ratio
of the peak value to the RMS value. 500Hz is the maximum fundamental frequency at which the
corresponding crest factor must be taken into account for accuracy calculations.
Low level considerations
For sensitive measurements, external considerations beyond the Model 2010 affect the
accuracy. Effects not noticeable when working with higher voltages are significant in microvolt
signals. The Model 2010 reads only the signal received at its input; therefore, it is important that
this signal be properly transmitted from the source. The following paragraphs indicate factors
that affect accuracy, including stray signal pick-up and thermal offsets.
