The Meter screen gives an overview of voltages and currents in all phases. The rms
voltages are shown neutral-to-line and line-to-line. Also frequency and Crest Factors are
shown. The Crest Factor CF indicates the amount of distortion: a CF of 1.41 means no
distortion and higher than 1.8 means high distortion. Use this screen to get a first
impression of power system performance before examining the system in detail with
other measuring modes. The number of columns in the Meter screen depends on the
power system configuration. Use the up/down arrow keys to scroll the Meter screen.
